In one sentence: bitcoin is digital money that moves between people without a bank in the middle, with a supply capped at 21 million coins. In one paragraph: the record of who owns what is a public ledger copied across thousands of computers. New transactions are grouped into blocks roughly every ten minutes by miners, who compete to secure the network and are paid in newly issued bitcoin plus fees. No company runs it and nobody can issue more than the rules allow. Open ledger, fixed issuance, no central operator - that is the whole design. Everything else people argue about is built on top of it. 💬 How would you explain bitcoin to a friend in one sentence?

Free airdrops - and the ones that cost you everything
An airdrop is a distribution of free tokens to wallet addresses, used by projects to reward early users or spread ownership. Real airdrops exist, and some have been generous. That is exactly what makes fake ones work. The fake version arrives as an unexpected token in your wallet or a message saying you are eligible, with a link to "claim". The claim page asks you to connect and sign - and the signature hands over permission to move your assets. A genuine airdrop never requires you to send funds first or reveal your seed phrase. If you did not expect it, do not interact with it. 💬 Have you ever found a random token in your wallet? Did you touch it?

What a security audit promises - and what it can't
A security audit is a review of a smart contract's code by specialists looking for bugs, logic errors and exploitable flaws before real money depends on it. A serious project publishes the report, including what was found and what was fixed. Audits genuinely reduce risk, but they are often read as a guarantee, which they are not. An audit covers one version of the code at one point in time; changes afterwards are outside it. It checks the code, not the team's intentions or the project's economics. Read the summary of findings, check the date, and treat "audited" as the start of your research rather than the end. 💬 Do you read audit reports, or just look for the word "audited"?

A burner wallet for the things you don't fully trust
A burner wallet is a separate, temporary wallet holding just enough for one purpose - trying a new app, minting something, claiming from a site you do not know well. If that interaction turns out to be malicious, the damage stops at the burner's small balance. The logic is simple compartments. Your main wallet, the one with your savings, never connects to anything experimental and never signs approvals it does not need. The burner takes the risk; you move out only what you want to keep. It takes a few minutes to set up and is one of the cheapest habits for protecting serious money. 💬 Do you keep a separate wallet for trying new apps?

Wash trading is when the same person or group trades with itself - buying and selling the same asset back and forth - to create the look of activity. No ownership really changes. The goal is to inflate volume, attract attention, or make a market look deeper than it is. It matters because volume is one of the first numbers people use to judge whether a coin is healthy and whether they will be able to sell later. Fake volume lies about exactly that. Cross-check it: does the volume match the depth of the order book? Is it spread across venues or concentrated in one? Volume without liquidity is a stage set, not a market. 💬 How do you judge whether a coin's trading volume is real?

A honeypot token looks like a normal token with a rising chart. You can buy it without trouble. When you try to sell, the transaction fails, because the contract was written so that only certain addresses can sell. The chart rises because nobody else can get out. Unlike a rug pull, nothing dramatic happens - the trap was in the code from day one. Before buying an unfamiliar token, look for evidence that others have sold successfully, check whether the contract is verified and reviewed, and be wary of anything that only ever goes up. A chart without sellers is not strength. It may be a cage. 💬 Do you check a token's contract before buying, or trust the chart?

A pump and dump is a coordinated scheme: a group buys a thinly traded coin cheaply, hypes it in chats and social feeds, and sells into the rush of buyers it created. The chart looks like a rocket followed by a cliff, and most of the people who bought the rocket end up at the edge of the cliff. The tell is the combination of a small, illiquid coin and a sudden wave of promotion. Before buying anything that is trending hard, ask one plain question: who is selling to me right now, and why? If the answer is "the people who told me to buy", the trade was designed with you as the exit. 💬 Have you seen a coin pumped in a group chat? How did it end?

A rug pull is when the people behind a crypto project take the money and disappear. The classic version: launch a token, pair it with real coins in a liquidity pool, market it hard, and once buyers have poured in, withdraw the liquidity. The token is still in your wallet. There is just nothing left to sell it for. The warning signs repeat. An anonymous team with no track record. Liquidity that is not locked. A contract that lets the creator mint new tokens or change the rules. Returns no real business could pay. None of these proves a scam on its own, but each is a question that deserves a clear answer before your money goes in. 💬 Which warning sign do you think people ignore most often?

Phishing is impersonation designed to get you to hand over access: a login page copied from the real one, an email "from support", a message saying your withdrawal is on hold. The page looks perfect because it was copied. The address bar is where it slips. The defences are unglamorous. Type important addresses yourself or use saved bookmarks. Check the domain character by character before entering anything. Treat urgency as a red flag - "act within 30 minutes" is there to stop you thinking. And remember that a real platform never needs your password, seed phrase or verification code sent to it in a message. 💬 What's the most convincing phishing attempt you've ever received?
