Binance will adjust the tick sizes of some spot trading pairs: according to a Binance announcement, the minimum price increments for 15 trading pairs will be updated by 13:00 Beijing time on October 29. This changes the smallest interval by which order prices can increase or decrease; it is not a change in token prices, nor does it mean any trading pairs are being added or delisted.
These trading pairs cover TRY-, USDC-, and USDT-denominated markets, and each new tick size listed is one-tenth of the old one. For example, the USDT trading pair for $ANIME will change from 0.00001 to 0.000001; the USDT trading pair for $POLYX will change from 0.0001 to 0.00001; and the TRY trading pair for $RVN will change from 0.0001 to 0.00001. The change applies to the quoting rules of specific trading pairs and should not be applied automatically to other markets for the same token.

Binance adjusted a funding rate calculation for TradFi perpetual contracts based on U.S. stocks: premium index data from the affected period will be excluded. Note that the announcement concerns how the data used in the calculation is handled; it does not announce the cancellation of funding rates, nor does it disclose the specific rates for any contracts after the adjustment.
According to a Binance announcement, a major U.S. overnight alternative trading system (ATS) experienced intermittent network connectivity issues between 11:46 and 14:30 Beijing time on October 21. Binance therefore decided to exclude all premium index data from TradFi perpetual contracts based on U.S. stocks during that period from the funding rate calculation at 16:00 Beijing time on October 21. These two times refer respectively to the period when the network issues occurred and the time of the funding rate calculation; they should not be confused.

Binance has announced five new bStocks spot trading pairs. But before looking at the trading times, it is more important to understand that what is being traded here is not the shares of listed companies themselves.
According to Binance’s announcement, spot trading for BOTB/USDT, BRKBB/USDT, KSTRB/USDT, TMFB/USDT, and VSTB/USDT is scheduled to open on October 21 at 20:00 Beijing time. The products are linked to company shares and ETFs. At the time the announcement was checked, this was still a scheduled opening time in the future, and should not be treated as evidence that trades had already taken place.
Not all related services will be available at the same time. The spot algorithmic trading bot is scheduled to go live alongside the listings, while the rebalancing bot is scheduled to be enabled within 24 hours after listing. The announcement also says that within one hour after listing, users can exchange tokens such as $BTC and USDT for bStocks through Binance Convert under a zero-fee arrangement. The zero maker-fee promotion for the five spot trading pairs mentioned above is scheduled to run until October 31 at 23:59 (UTC). These arrangements apply separately to conversions and maker orders; they should not be summarized as meaning that every stage of trading is free.

Small liabilities in Binance Cross Margin accounts will soon be subject to a routine daily cleanup process. According to a Binance announcement, this will take effect from 00:00 (UTC) on October 27, 2026, and apply to accounts that meet both of the following conditions: their total outstanding liabilities across all assets are worth less than $1, and they have had no fund activity in the past six months.
“No fund activity” does not mean that absolutely no actions have been taken in the account. The announcement lists fund activity as including transfers into or out of a Margin account, borrowing and repayments, and using functions such as Close Position, Close All Positions, and Repay All. Unfilled orders placed more than six months ago do not count as fund activity. To determine whether an account falls within the scope of the cleanup, both the total liabilities and fund activity during this period must be considered—not just whether the account has a small outstanding loan.

Binance will adjust the collateral ratios for a group of assets starting at 14:00 Beijing Time on October 23. The changes are expected to take about 30 minutes to complete. They affect cross-margin borrowing and transfers, Portfolio Margin, and the tiered collateral ratios for Portfolio Margin Pro (PM Pro). The impact on an account cannot be determined by looking at a single percentage, as the same asset may have different ratios under different modes.
According to a Binance announcement, under Cross Margin and standard Portfolio Margin, the collateral ratios for $POL , $SHIB , and XLM will rise from 50% to 60%, while those for $COW , NEXO, RVN, and SAND will rise from 10% to 30%. The collateral ratio is a parameter the platform uses to calculate the value of collateral assets. It is not the market price of these assets, nor does it mean that an account's available borrowing limit will change by the same proportion.

Binance will adjust the leverage and margin tiers for several USDT-margined perpetual contracts. The changes are scheduled to begin at 14:30 Beijing time on October 30 and are expected to be completed within about an hour. The announcement specifically notes that positions opened before the adjustment will also be affected, and that running Futures Grid bots may be terminated due to changes in the tiers.
This change cannot be simply summed up as a “uniform leverage reduction.” Take the perpetual contracts for $APR and $AIO as examples: for the first tier, covering notional positions of up to 5,000 USDT, maximum leverage will be reduced from 50x to 25x, while the maintenance margin rate will rise from 1.50% to 2.00%. The maximums for some larger position tiers in the same groups will also be lowered. This means the changes affect not only the available leverage multiples; the tier your position falls into matters as well.

bStocks collateral valuations will no longer depend solely on trading hours in traditional regional markets. According to a Binance announcement, starting at 08:00 Beijing time on October 24, its collateral index price mechanism is set to support dynamic updates around the clock. The change applies to the index price used for collateral valuation; it does not mean that traditional markets will also begin trading around the clock.
During non-trading hours, such as weekends, holidays, and daily maintenance windows, the index price will be based on Binance trading prices and calculated using an order-book EWMA model. To limit unusual volatility during these periods, the mechanism also sets a price-movement cap specifically for collateral valuation. When switching out of this mode, it will transition gradually through a weighted blend of the old and new calculation methods, reducing the risk of a sudden price jump caused by the switch.

Binance has brought “describe an idea in natural language, generate a strategy, run a simulated test, then approve it for live trading” into a single product workflow. According to Binance’s October 19 announcement, Binance AI Pro began rolling out on the web and in the app that day. This is the product rollout plan announced by the platform and does not mean that it is already available to users in every region.
The announcement says users can describe a strategy idea in a conversation, review the generated workflow, and continue to revise it. On the web, users can view the conversation and workflow side by side; in the app, they can build and adjust strategies through chat. Before committing real funds, the product offers simulated testing with hypothetical funds. But being able to test a strategy does not mean it has been proven effective, and the announcement provided no independently verifiable performance data for strategies.

If you’re an ordinary person with just 300U and not much experience, you can use this approach as a guide. Experienced traders can move on; the rest of this is about how to lose less money learning with a small account.
First, accept this reality: if you buy spot with 300U, even if your assets double, you’ll only make 300U. But with high leverage, even a small move in the wrong direction can quickly wipe out your entire stake.
So, the best way to think of 300U isn't as “capital to turn your life around,” but as a ticket into the market. There’s only one goal: learn about the market at a limited cost while staying in the game for as long as possible.

Have you ever been confused by claims of “one million TPS”? When evaluating a high-performance public blockchain, don’t start with its theoretical lab maximum—look at whether people are actually using it on the live network.
$SOL ’s theoretical speed isn’t what makes it most noteworthy. The data shows that its actual TPS has remained in the thousands for an extended period, while many public blockchains claiming hundreds of thousands or even millions of TPS may only achieve a few hundred in real-world operation. For everyday users, this makes for a simple rule of thumb: no matter how impressive the specs look, if real transactions can’t be processed, speed is just a marketing number.
I use just three metrics to evaluate high-performance public blockchains.

Do you also feel like more and more people around you are talking about $BTC , yet hardly anyone actually holds their own private keys?
By the standards of self-custody, the amount of crypto shown in an exchange account isn’t the same as the amount you truly control. The test is simple: Do you have your own wallet? Can you independently back up your seed phrase or private keys? Can you make on-chain transfers without the platform’s approval? Even if you hold only a small amount, it’s truly self-custody only when you control the private keys yourself.
There’s a classic example in my family. More than a decade ago, my sister-in-law followed the trend and spent over 20,000 yuan on a set of used mining rigs. According to family members, they came with 2 bitcoins. She hired people to mine, providing room, board, and wages, but the neighbors downstairs complained about the noise almost every day, so in the end she had to sell the rigs. When she bought them, one bitcoin was worth about 4,200 yuan; when she sold them, it was about 4,700 yuan. My dad later remarked, “The profit didn’t even cover the electricity bill.”

Are you like this too: after selling $BTC , you’re relieved when the price drops, but frustrated when it rises? Even though you’ve already exited, do you find yourself checking the market more often than when you were holding?
That was me. I bought a few bitcoins in 2019, made about 100%, and got out. Later, when I saw people holding on for years, even decades, I couldn't help wondering: Why can they hold on, but I can't?
The problem often isn't your judgment, but not having an exit strategy in place before you sell. When ordinary investors are sitting on a profit, they're most afraid of watching it vanish. After selling, a rising price can tempt them back in, potentially exposing them to volatility all over again.

If you find the AI crypto narrative too abstract and can only focus on token prices, I feel the same way. The change worth paying attention to isn’t just another new concept—it’s that AI is moving from being a “chat tool” to becoming a real user of on-chain protocols.
Uniswap has released seven skill documents for AI agents, covering areas such as V4 security fundamentals, configuration, deployment, swap integration, liquidity planning, and swap planning.
Here, “skills” can be understood as instruction manuals for AI. After reading the documentation, AI can learn how to use protocol features and, with the necessary permissions, carry out tasks such as swapping, deploying, and planning liquidity.

Have you run into this too? The same meme, the same name, but one version on each of two chains—and both communities claim theirs is the “official” one?
Don’t rush to see which one is rising faster. When evaluating these split-token projects, first look at who owns the IP—it often matters more than the chart.
The dispute over $ASTEROID is a typical example. The ETH version had been active earlier, and its community had organized charitable efforts. Before Musk made the related remarks, its market cap had already topped $160 million. The SOL version launched through Bags, and its creator Liv Perrotto’s mother, Rebecca Perrotto, received about 2,013 SOL in fee revenue. She said the platform’s proceeds would go toward establishing a memorial foundation.

If you only have a few tens of thousands in spare cash and keep jumping back and forth between U.S. stocks and crypto, don’t rush to ask which one will rise more.
The real question is: which market has a clearer structure right now and better suits your trading skills?
I judge whether a market is worth trading based on just three things: whether key levels are clear, whether trading volume and liquidity are stable, and whether I can calculate my stop-loss in advance. Getting the direction wrong isn’t scary; what’s worst is getting whipsawed by prices, seeing the order book suddenly thin out, and then not even being able to explain why I lost money.
Based on how the market is behaving right now, I think trading $BTC is quite challenging. It may look like it’s constantly moving, but there aren’t many opportunities to get in and out smoothly. When liquidity drops, false breakouts, sharp pullbacks, and slippage all get worse. $ETH has similar issues: you can spend plenty of time watching the market without necessarily getting more certainty.

Are you like this too: when Bitcoin drops, you’re afraid to look, but when it rises, you’re quick to ask, “Can I still buy now?”
If you’re also an everyday investor who doesn’t have time to watch the market and is afraid of making the wrong move, feel free to skip this. Here’s just one practical method: don’t try to guess the exact price point for $BTC , write down your own buying rules first.
“Can I still buy?” isn’t really a complete question. At the same price, the answer will be completely different for someone who can handle volatility and plans to hold long term than for someone eager to make a quick profit. The first thing to figure out is how long you can leave this money invested—and how much of a drop would keep you up at night.

Do you get this feeling too? When ETH surges, you’re afraid of missing out; when BTC reaches a key level, you worry it could suddenly pull back.
What really matters this time isn’t which asset rises more sharply, but whether the rebound can hold.
The market picture is clear: $ETH ETH climbed to around 1,982 intraday, clearly outperforming $BTC over the same period. Bitcoin, meanwhile, rose to around 65,700, tested the 65,500 area several times, then came under pressure and pulled back.
This means ETH’s strength still looks more like a move driven by localized buying for now; it shouldn’t be taken as confirmation that the broader market has broken out. Chasing the rally based on gains alone can make it easy to overlook Bitcoin’s continued struggle around a key resistance zone.

Do you also think that the more you monitor, the faster your arbitrage bot will be?
Quite the opposite: on Solana, where thousands of transactions are generated every second, monitoring everything can quickly overwhelm your bandwidth and CPU and increase latency. By the time you’ve handled the real price difference, the opportunity may already be gone.
A more practical approach is called “inventory-driven monitoring”: instead of watching the entire network, you only monitor high-value liquidity pools selected in advance. For ordinary developers, this means you don’t need to start by piling on expensive nodes; first, narrow the monitoring scope.
There are three steps.
1. Build a comprehensive index
Get pool lists from protocols such as Raydium and Orca, then compile the pool addresses, token mints, decimals, vaults, and other information in a consistent format. For example, if the same trading pair on $SOL appears on two protocols, it’s worth considering for the next round of filtering.
