Every $BTC new coin comes from a calculation, not a printing press.
Someone turns on a powerful computer and competes against thousands of others to solve a mathematical puzzle. The first to solve it adds the next block of transactions to the chain. And the network pays them for it—with coins that didn’t exist a second earlier.
That payment has a built-in limit. The protocol has a written rule: after a certain number of blocks, the payment is cut exactly in half. It doesn’t grow or change at anyone’s discretion; it’s simply cut. Again and again, always in half from the previous amount, approaching zero without ever quite reaching it.
The payment earned by whoever mines is called the block reward. And the cut that divides it in two is called a halving.
KEY CONCEPTS
- The reward isn’t fixed forever: it decreases according to a rule in the code, not anyone’s decision.
- Mining isn’t guaranteed profit: electricity, hardware, and competition all come into play.
- Halving isn’t exclusive to Bitcoin: other networks that use mining have similar adjustments.
- You can’t mine with just any laptop anymore: today it requires specialized equipment and a lot of computing power.
Just as a central bank decides how much money to print, the code of $BTC decides how much to issue. But that rule is set from the start, and no one can change it midway.

A blockchain doesn’t break on a whim: it breaks because people stop thinking alike.
Imagine a hundred nodes validating the same history. Seventy-five install a new rule. Twenty-five refuse. That’s where two paths begin.
On the first path, the change is so significant that the old software no longer recognizes the new blocks. Those who didn’t update are left on their own chain, with their own coin, and the two paths never come back together. That’s a hard fork.
On the second path, the rules become stricter. But the old nodes still accept the new blocks, even if they don’t understand every detail. Not everyone has to update on the same day. The chain remains one. That’s a soft fork.
Neither side is more right than the other when the network splits: each believes it’s following the correct rules, but they no longer speak the same language. $PAXG lives on a chain that never needed to fork: it was created as a new token, not as a branch of another project.
KEY CONCEPTS
- Not every fork creates a new coin: almost no soft fork changes anything users notice.
- A hard fork isn’t decided by one person: enough nodes need to install the change for the new chain to survive.
- Lots of users don’t guarantee real consensus: if only a few actors make the decisions, agreement is fragile, even when the community seems huge.
- Consensus isn’t a popularity vote: it’s a technical mechanism that requires all nodes to share the same ledger.
Next time you see two coins with similar names, you’ll know the order: first, people’s agreement broke down; then the chain did.

When someone sends $BTC, the transaction isn’t recorded instantly. First, it competes against thousands of computers trying to guess an exact number. It’s that simple. And that tough.
Those computers bundle pending transactions into a block and attach an arbitrary number called a nonce. They run the whole package through a function that turns any data into a fixed code of letters and numbers: a hash. If the code doesn’t meet the required rule (for example, starting with several zeros), they try another nonce. And another. And another. No elegant equations. Just brute force, attempt after attempt, nonstop. The first computer to find the right nonce earns the right to add that block to the chain and claim the reward.
This work of trying numbers until one is right, block after block, is called mining.
KEY CONCEPTS
- It’s not about solving an equation with pencil and paper. It’s pure trial and error: trying random numbers until one meets the condition.
- Not just any computer will do. You need hardware designed to repeat those attempts nonstop, at high speed.
- Mining doesn’t guarantee a profit. If another computer finds the number first, your work is worth nothing.
- Joining a mining pool improves your chances of earning a reward, but doesn’t guarantee a profit: the reward is shared among everyone who contributed computing power.
Each block in the chain carries the evidence of that real effort. That’s why changing old data would mean repeating that entire race from scratch, against the whole network.

Most wallets thought to be lost weren’t hacked: they were lost because of a backup that was never tested.
A typical case: someone stores 500 $USDC in a desktop wallet, sets a password, and considers the matter settled. They never copy the file containing their keys to another location. The drive fails. Access is lost, even though the funds remain intact on the network.
That file is called wallet.dat: it holds the key that moves the funds. Without a copy somewhere else, it’s the only thread connecting you to the money, and if it’s lost, no one can recover it. Keeping a separate copy is what backing up a wallet means.
There’s another feature that’s often confused with a backup. Setting a password that prevents funds from being spent, even if someone has the device in their hands, without making the rest of the drive invisible: that’s encryption. It solves a different problem.
KEY CONCEPTS
- Encryption protects against spending with a password, but it doesn’t encrypt the device’s other files: these are separate layers.
- A backup isn’t a one-time task when you switch wallets: it protects against any failure, and if you’ve never tested it by restoring from it, it isn’t a real backup.
- A cold wallet reduces the risk of online theft, but requires maintenance: connect it from time to time and check that the backup phrase is still readable.
- A web wallet manages the keys for you, but doesn’t provide complete anonymity or work like insurance that returns your funds if you lose access.
The wallet you use every day depends on a file or phrase that no one checks until it’s too late. Testing the backup before you need it can make the difference between a scare and a real loss.

Validating a block no longer has to consume energy. It can simply require putting something at stake.
Imagine a validator who sets aside 100 coins as collateral before they can confirm transactions. If they approve a valid block, they receive a small reward, say 2 coins. But if they try to slip in a fraudulent transaction and the network detects it, they lose some or all of that collateral. There’s no need to solve a mathematical puzzle that consumes electricity on a massive scale. You just need to have something to lose.
This mechanism is called proof of stake. Ethereum, for example, switched to this model so validators can $ETH back the network with locked-up capital instead of computation.
KEY CONCEPTS
- The collateral isn’t just for show: if the validator misbehaves, they lose it. There’s still a cost; it’s just taken a different form.
- Depositing collateral doesn’t automatically make anyone honest. Without a clear penalty for backing an invalid chain, some validators might try to support several versions at once.
- Not every part of the industry uses this model, or adopted it at the same time. Other networks still use the previous method, spending electricity to validate.
- Agreement on which block is valid is a technical process among validators, not a popular vote among everyday users.
And that’s the real difference from the energy use of the past: electricity is no longer burned to prove commitment; instead, validators put their own capital at risk. Same problem, different collateral.

Twelve words can be worth more than everything in your bank account. Or they can lose it forever.
When a wallet is created, the software generates a list of twelve words in a specific order. They’re not a password you can change: they’re the master key to everything inside. With them, anyone can reconstruct the wallet and move the funds. Without them, if your phone breaks, there’s no tech support that can restore access.
Here’s a simple example. Someone installs a wallet to store $SOL. The app shows them the twelve words just once and asks them to write them down on paper. Instead, they take a screenshot and save it to the cloud. Months later, their email account is compromised. The attacker doesn’t guess any passwords: they search through the photos, find the twelve words, and move the $SOL in minutes. There was no sophisticated hack. There was a poorly stored copy.
That list of twelve words has a name: a seed phrase.
KEY CONCEPTS
- A seed phrase cannot be reset. If a platform offers to recover it for you, it keeps a copy on its servers, changing who controls the money.
- Storing it in the cloud, in email, or in a photo is like leaving it somewhere someone else can read it. Handwriting it on paper and keeping it offline is still the safest option.
- Never share the complete phrase with anyone, not even legitimate tech support. No legitimate platform needs it to help you.
The twelve words aren’t just another piece of account information. They’re the difference between owning your funds and depending on someone else’s goodwill.

Using electricity isn’t wasteful in Bitcoin. It’s the price of trying to cheat. And nobody pays it twice.
Here’s how it works. Thousands of computers around the world compete to guess a number that, when combined with the block’s data, produces a result with a certain number of zeros at the beginning. There’s no formula for skipping this step. It’s like rolling a giant die over and over until you get the number you’re looking for: there’s no trick, just repetition and energy consumption. It uses real electricity, real equipment, real money. That’s the underlying trick: rewriting the history of $BTC to spend the same coin twice would mean repeating all that work faster than the rest of the world combined. Extremely expensive. Slow. Almost nobody tries.
This computational expense that buys honesty is called proof of work.
KEY CONCEPTS
- Not every cryptocurrency uses proof of work. Ethereum left it behind in 2022 and now validates transactions with capital at stake, not electricity.
- Solving the puzzle doesn’t mean decrypting anything. The function that combines the data can’t be reversed, so there’s no way to guess without trying blindly.
- Using energy doesn’t make a network invulnerable forever. It makes attacking it extremely costly; it doesn’t offer an eternal guarantee.
- The fact that lots of people use a currency doesn’t mean the network agrees on anything. Consensus is built block by block, not by user count.
The idea behind $BTC was never to hide the electric bill. It was to turn it into proof that nobody lied without paying the price.

- Using energy doesn’t make a network invulnerable forever. It makes attacking it extremely costly; it doesn’t offer an eternal guarantee.
- The fact that lots of people use a currency doesn’t mean the network agrees on anything. Consensus is built block by block, not by user count.
The idea behind $BTC was never to hide the electric bill. It was to turn it into proof that nobody lied without paying the price.

Thousands of computers scattered across the planet manage to agree on every transaction, without anyone directing them from a central office. No one is in charge up there.
Let’s think about a simple example. Someone has 10 coins and tries to send them to two different people at the same time. With thousands of nodes watching, each one checks the balance before accepting the operation. And the second transaction is rejected. No one spends the same coin twice. The majority of the network has already validated the first one.
Networks like the one that supports $BNB work in a similar way. A group of validators reviews each new block and only accepts it if the majority agrees. Without that agreement, the block is not added to the chain. It’s that simple.
That collective agreement among independent machines, with no boss and no popular vote, is called consensus.
KEY CONCEPTS
- Consensus is not a popular vote or an opinion poll. It is a technical rule that is enforced automatically, without asking anyone for permission.
- Having many nodes does not guarantee real decentralization. If almost all of them run the same program, a single bug in that software affects them all equally.
- A high amount of computing power also does not mean a fair distribution of power. If that power is concentrated in a few hands, the network remains vulnerable.
- Social consensus, the community’s support for the rules of a currency, is not the same as technical consensus, which validates each transaction.
Understanding consensus helps explain why a network with no boss can be harder to manipulate than a bank with a single person in charge.

A smart contract is neither a contract nor smart. It’s a marketing phrase awkwardly slapped onto it.
Let’s imagine something simple: if A deposits 20 $ETH before Friday, the code releases those funds to B. Nobody signs paperwork or calls a notary. The code checks the condition and acts on its own.
What if the condition isn’t met? The code doesn’t need anyone to decide: it simply doesn’t release the funds.
Under the hood, the code lives as copies on thousands of computers that agree on each block of data, linked together with a cryptographic signature that’s almost impossible to break. Each node runs the same copy, so the result is the same for everyone.
This is what they call a smart contract.
But here’s what almost nobody tells you: the code does what it says, not what the team meant. If there’s a bug, it still executes. And since it’s already been published on the network, nobody can go in and fix a line. Fixing it means publishing a new contract or migrating the entire network, and that’s neither quick nor free.
KEY CONCEPTS
- It isn’t a legal contract signed in front of lawyers. It’s code that runs on its own, without traditional legal recourse.
- It doesn’t need a person to check every step. By design, it executes without constant human supervision.
- A programming error doesn’t stop the code from running. It executes anyway, because it can’t distinguish intention from outcome.
- Many contracts rely on oracles to read external data. If the oracle fails, the contract fails—even if its code is perfect.
When people talk about a DeFi hack, this is almost always the cause: a line of code doing exactly what it said, not what someone imagined.

Two people buy $BTC in the same minute and end up paying different prices. One asked that the order be executed immediately, without setting a number. The other set a limit and waited until the market reached it.
The order book moves quickly. Ana asks for her purchase to be executed right away. The exchange gives her the best available price at that moment: she pays 84,700 USDT. That is a market order. It prioritizes speed over price.
Bruno is in no rush. He sets the maximum price he will pay: he puts 84,500 USDT and waits. If $BTC drops to that level, he buys. If it doesn’t, nothing happens. His order may remain unexecuted all day.
As of October 3, 2026, 11:45 UTC, BTC was trading at 84,659.46 USDT and had fallen 2.13% over the last 24 hours.
What Bruno did has a name: a limit order. You set the price. You give up execution certainty.
KEY CONCEPTS
- A market order prioritizes speed, not the price you see on the screen. The number can move while the order is being filled.
- A limit order fixes the price you’re willing to pay or receive. It may go unfilled if the market never reaches that level.
- Not all exchanges work the same. Standard ones match orders in a central order book. Peer-to-peer connects the counterparties directly, without holding the funds.
- Leaving $BTC stored on an exchange for years is not the same as having your own control. A hack won’t return your balance the way a bank would.
This difference explains why the price on the screen almost never matches the final price you pay. But the order’s mechanics matter as much as the decision to buy or sell.

Every computer that stores a complete copy of the transaction history has a say in which transaction is valid. That’s it.
Imagine a network with ten computers storing that complete copy. If six of them run exactly the same program, that program decides what happens when there’s an error or a controversial update. It doesn’t matter how many computers are connected. But if the majority follows the same code, real control lies with whoever writes that code—not with the total number of participants.
Those computers that store the history and validate every transaction are called a node. Bitcoin works this way: thousands of nodes spread around the world. No one commands. No one asks for permission. A token like $PAXG also lives on a network of nodes, and its gold backing matters little if those nodes are concentrated in a few hands.
KEY CONCEPTS
- Not all nodes do the same thing. Some store the full history, others only part of it, and some additionally compete to create new blocks.
- Having thousands of nodes doesn’t guarantee decentralization. If the majority responds to the same few organizations, that number is just decorative.
- The program each node runs matters as much as the number of nodes. A single type of software concentrates decision-making power in the hands of whoever programs it.
- Bitcoin has no owner and no central headquarters. It’s thousands of independent computers agreeing with each other—not a company issuing orders.
Counting nodes tells you little. Asking who controls them and with what software says almost everything.

Hardly anyone reads the document a project publishes before asking you for money. And the people who want you to read it the least are precisely those who don’t have anything solid behind it.
That document should explain, in detail, what problem the project solves, how it works internally, and where every dollar comes from. It’s not a sales brochure. It’s the technical and financial foundation on which someone asks you to trust your money.
A simple example. A project promises to return $100 for every 100 tokens, backed by $USDC held in a custody account. If that document doesn’t say which account the money is in or who reviewed it, the promise is worth no more than a tweet. A number without a verifiable destination is just a pretty figure tucked into a PDF.
In crypto jargon, that document has a name of its own: a whitepaper.
KEY CONCEPTS
- A whitepaper is not a contract. No one owes you anything legally just because they promised it there.
- Lots of pages and graphs are not synonymous with a serious project. Sometimes it’s exactly the opposite.
- If there’s no public code repository or real names for the team, that’s already a signal—not a minor detail.
- Reading it all helps, but it doesn’t replace checking whether an external party audited that code or those reserves.
No one will warn you when a whitepaper is empty inside. That reading is up to you—just as calmly as you would review a contract before signing it.

A single password no longer suffices to protect your cryptocurrency account.
For years, the code that arrived by text message seemed enough. It isn’t anymore. It travels over the phone carrier’s network, and that network can be hijacked without touching your phone. What does hold up is a code generated within the device itself, without going through any carrier: it can be an app or a physical key.
Think of an account with $BNB saved there. With just one key, the thief steals one thing. With a well-chosen second factor, they have to steal two—and one of them never leaves your pocket.
That’s two-factor authentication: a second lock that doesn’t share a key with the first.
KEY CONCEPTS
- A text-message code no longer counts as a reliable second factor: it travels over a network that can be hijacked without touching your phone.
- A code generated inside the device—whether an app or a physical key—doesn’t depend on the phone carrier. That’s why it resists better.
- Using the same key for email and for the second factor isn’t double protection. It’s the same door painted twice.
- No method is invulnerable, but each different layer forces the attacker to solve a new problem, not the same one twice.
The same care you already use to store your private keys is what you should use to choose your second factor: not everything that promises to protect does so equally.

When you buy an NFT, you don’t buy the image.
You’re buying a record that says who owns that image. That’s it. The file almost never lives inside the chain; it’s too heavy. The token stores a link that points to it, stored on another server. If that server goes down, the token is still there. The image, not so much.
And here comes the same old mistake: thinking that “unique” is the same as “valuable.” It isn’t. Imagine someone mints the same photo ten times. Each copy has its own token number. That’s ten unique records, but the photo is identical in all ten. Uniqueness is set by the code. The price is set by someone else.
That—the record that distinguishes one piece from all the others—is what’s known as a non-fungible token, or NFT.
On Ethereum, most follow the ERC-721 standard: each piece has its own identifier, and you can’t swap one for another as easily as you can with $ETH.
KEY CONCEPTS
- An NFT is not the file: almost always, it’s a link pointing to a file stored off-chain.
- “Unique” is not synonymous with “valuable.” Uniqueness is guaranteed by the contract; the price is decided by demand.
- An NFT is not the same as a governance or utility token: those give voting power or access, but they don’t prove ownership of a piece.
- Not every NFT collection is 100% non-reproducible. Standards like ERC-1155 mix unique pieces with repeatable ones in the same contract.
It’s like having the certificate for a painting without the painting: the paper is real, but the artwork is still hanging on another wall.

You’re buying a record that says who owns that image. That’s it. The file almost never lives inside the chain; it’s too heavy. The token stores a link that points to it, stored on another server. If that server goes down, the token is still there. The image, not so much.
And here comes the same old mistake: thinking that “unique” is the same as “valuable.” It isn’t. Imagine someone mints the same photo ten times. Each copy has its own token number. That’s ten unique records, but the photo is identical in all ten. Uniqueness is set by the code. The price is set by someone else.
That—the record that distinguishes one piece from all the others—is what’s known as a non-fungible token, or NFT.
On Ethereum, most follow the ERC-721 standard: each piece has its own identifier, and you can’t swap one for another as easily as you can with $ETH .
KEY CONCEPTS
- An NFT is not the file: almost always, it’s a link pointing to a file stored off-chain.
- “Unique” is not synonymous with “valuable.” Uniqueness is guaranteed by the contract; the price is decided by demand.
- An NFT is not the same as a governance or utility token: those give voting power or access, but they don’t prove ownership of a piece.
- Not every NFT collection is 100% non-reproducible. Standards like ERC-1155 mix unique pieces with repeatable ones in the same contract.

On the $BTC network, changing a single character in an old transaction breaks every block that came after it.
Think of three consecutive blocks. The first stores some transactions and generates a unique fingerprint from that content. The second adds that fingerprint to its own data and creates a new fingerprint. The third does the same with the fingerprint from the second. Each block carries the summary of the previous one.
What if someone changes a digit in the first block? Its fingerprint changes completely, character by character. The second block, which stores the old fingerprint, no longer matches. And since the third depends on the second, the break continues onward. Modifying the past means rewriting everything that came after it. Simple, but lethal.
That fingerprint that summarizes a block and is passed on to the next is what’s known as a hash.
KEY CONCEPTS
- A hash can’t be reversed. No one can recover the original data from the result. It’s only used to verify that the content hasn’t changed.
- A hash doesn’t resemble the source data. Changing a comma alters the entire result.
- The chain isn’t a single database. It’s a network of copies that must match before a change is accepted.
- A hybrid blockchain leaves some information public and another restricted, but the link between blocks works the same way.
That’s why an old block becomes almost frozen as soon as new blocks are added on top. Understanding this explains why rewriting the history of a large network is almost impossible in practice.

There is no perfect wallet. Each one covers a gap and opens another.
So which one do you use? It depends. Are you going to spend today or save for years.
Imagine you have 1 $BTC. You leave 0.05 in a wallet that lives connected to the internet, ready to spend quickly. The rest, 0.95, is kept somewhere that never touches the network unless you need it.
And that gap between what’s within reach and what’s stored away is, at the end of the day, the whole custody game.
KEY CONCEPTS
- Hot wallet: it stays connected, always ready for whatever you move. But being online all the time also means being exposed all the time.
- Cold wallet: it connects only at the moment of signing. The rest of the time it stays offline, which slows down remote theft. That said, it’s not automatic: you still need to back it up and take care of it.
- Hardware wallet: a physical device stores the keys away from any computer and connects by cable only to sign. It blocks attacks that come in over the internet, but it doesn’t prevent you from losing it or having it taken from you in person.
- Paper wallet: the keys are written or printed, with no cable and no chip involved. No hacker can touch it remotely, but fire, water, or a careless move can erase it forever.
Storing crypto is like storing cash. A little in your pocket for everyday life, the rest locked away where only you can reach.

Many people think that buying an asset on a network is the same as buying the network’s coin.
That’s not the case. Each network has a single native currency, the one that pays transaction fees and powers smart contracts. Anything else circulating there is something different.
Think about $BTC. Bitcoin has a single real coin: bitcoin, and it can be divided into tiny parts. You buy a little piece without taking the whole unit.
Now think about another network, where a project launches its own asset. That asset pays fees using the network’s native currency, but it isn’t that currency. It’s a passenger, not the owner of the vehicle.
That’s what’s called a token.
It can represent a vote within a protocol, ownership of a unique digital artwork, or a coin that was born as a joke on social media. None of those assets is the native currency of the network where it lives.
KEY CONCEPTS
- Just because a token runs on the same network as the native currency doesn’t make it that currency: these are different assets.
- A governance token gives you a vote in protocol decisions, not an assured profit.
- A native coin like $BTC is divided into very small parts. A non-fungible token doesn’t get divided: you either have it in full or you don’t.
- A meme coin goes up and down based on attention on social media, not because it has guaranteed utility within the network.
The next time you read the word token, check which network it depends on and whether that network already has its own native currency. That information changes everything.

When you see 0.1 $BTC in your exchange balance, you assume that bitcoin is already yours.
It isn’t. Not yet.
That number lives in the platform’s database, not in a blockchain address that only you control. Most exchanges pool money from thousands of users into a few big wallets. Your balance is an accounting entry. Not a bitcoin set aside with your name on it.
You deposit 0.1 $BTC. The platform records 0.1 in your account, mixed in with other users’ deposits. But if that company goes bankrupt, you don’t claim “my bitcoin”: that bitcoin no longer exists as a separate asset that is yours. You’re just one more creditor, in line with thousands of others. And whoever decides how what’s left gets distributed is a judge—not you.
That’s what custodial balances are: someone else holds the asset, and you trust their word.
KEY CONCEPTS
- An exchange isn’t a bank. There’s no deposit insurance that will return your bitcoin if the platform fails or gets hacked.
- Not all exchanges operate the same way. Some centralize orders in a central order book and hold your funds during the transaction. Others connect buyers directly with sellers.
- Just because a platform is large or has been around for years doesn’t make it secure by default. Crypto history has seen exchanges that looked solid and ended up being hacked.
- Having bitcoin “on the exchange” means having a claim against a company—not the asset itself.
Buying and selling there makes sense. Keeping your savings there for years means giving someone else the final say over something that belongs to you.

One wrong character and the $BTC ends up at an address that isn’t yours. No going back.
Not because someone intercepts it. But because the network reads exactly what you sent it. If the string is incorrect, that’s the destination. There’s no one to validate whether the recipient was the person you intended.
An address is a string of between 26 and 35 characters, case-sensitive. It’s not an account. It has no owner and no contract behind it. It’s the result of compressing your public key, which in turn is generated from a secret number that never leaves your wallet.
That secret number is the private key. Whoever has it can authorize a transfer of funds. They do so by producing a mathematical proof that the network verifies without seeing the secret. That’s called a digital signature.
KEY CONCEPTS
- An address is not an account: it has no registered owner, just mathematics.
- The address and the public key are not the same: the address is the compressed version of the public key.
- Generating an address doesn’t require an internet connection: the process happens inside your wallet.
- Losing the private key means losing the funds: there’s no recovery without that number.
The network can’t tell the difference between a typo and an intentional transfer. It reads the string and executes.

Three crypto scams wipe out wallets every day. And all three work the same way: they rush you and ask for a key.
The first arrives by email or message. It looks like an official notice from a platform. There’s a problem with your account, they say. You have to click right now. The link takes you to a fake page that steals your password. This is called phishing.
The second is someone who pretends to be technical support. They tell you they detected suspicious activity. To "protect you," they need your seed phrase. No legitimate support team ever asks for that.
The third promises free crypto. A celebrity recommends it, or a giveaway says they’ll double the $BTC you send. If you send anything, it disappears. The “gift” was the bait.
KEY CONCEPTS
- No real platform asks you for your seed phrase via message. If someone asks for it, it’s a scam, no matter how convincing it sounds.
- Urgency is a tactic. Scammers create urgency because it overwhelms good judgment.
- A link can look legitimate and still lead to a fake page. Before entering any information, check the full site address.
- Celebrities don’t hand out free crypto on social media. Those posts are always fake.
If something rushes you and asks for a key, close the window. You don’t need any further signs.

WarshPushesToScaleBackForwardGuidanceAndDotPlot

🚨 THIS COULD BE BAD NEWS FOR $BTC !
I think Warsh’s push to scale back forward guidance and the Dot Plot could create another source of pressure for the crypto market.
Without clear signals from the Fed, investors will have a harder time predicting future interest rates, making riskier assets less attractive during periods of uncertainty. #WarshPushesToScaleBackForwardGuidanceAndDotPlot
For me, the biggest concern is that rates could remain higher for longer than the market expects. This would limit liquidity and make it harder for Bitcoin and especially altcoins to sustain a strong rally. With investors forced to react to every new inflation and employment report, volatility could increase significantly.
In my view, this is a bearish development for crypto in the short term. If uncertainty grows and rate-cut expectations weaken, I believe the market could face renewed selling pressure, with altcoins likely to be more vulnerable than Bitcoin.
