What exchange inflows are. Coins sitting in a personal wallet can't be sold - first they need to be sent to an exchange. That's why a rise in transfers to exchange addresses is read as a signal: some holders are preparing to sell. It's not a guarantee of a sale, but it is a supply reserve already sitting next to the order book.
Why now. According to CryptoQuant, these are primarily short-term players looking to lock in profit after a sharp and strong altcoin market rally. Long-term holders usually don't rush during such moves.
Why the analogy with October 2025 is dangerous. Back then, exchange inflows also peaked, and a fresh correction in BTC followed. But the difference is in the market phase: a year ago the market was bearish, now analysts describe it as bullish.
What this means for a trader. CryptoQuant's base case is a mild correction or sideways movement in altcoins, not a collapse like the one a year ago. The practical takeaway is simple: supply on exchanges has grown, so sharp dumps in alts become more likely, and thin order books in small coins move faster. It's worth watching the inflow dynamics themselves: if they keep rising, seller pressure will persist.
Holding alts and watching these inflows?
Familiar: you didn't fully capture the rally, and now you're sitting there wondering whether to take profit or wait. And on your own deposit, even a good altcoin entry is just a few hundred dollars, not a result. Prop trading closes the gap between your trading and your account size: you pass a challenge and trade the company's notional capital. But every prop firm has its own coin list, its own limits, and its own drawdown calculation. It makes more sense to figure this out before the next altcoin move, not after it.
