Through the bull and bear markets, there are two core principles. First, in terms of mindset, abandoning the idea of earning interest—it's a habit from the fiat currency world where we store savings and earn interest. But why interest? Because fiat currency is subject to inflation; interest only slows down the depreciation. Bitcoin is different. Its supply is fixed in the code, with no central bank to change monetary policy, and no one can print more. Its value model is gold, not bonds. It doesn't rely on paying interest to appreciate; it depends on consensus. Holding Bitcoin profits from price increases, not from issuance growth. So don't think about "earning interest"—that's a leftover mindset from fiat currency. Second, in practice, reduce the time funds stay on exchanges by using cold wallets. A little-known fact: cold wallets can store not only BTC and ETH but also stablecoins like USDT and USDC. Treat exchanges as tools, not banks. Keep all funds in your wallet normally; only deposit when you need to trade, and immediately withdraw after trading. Here's a calculation: assuming an exchange can operate stably for about four years on average, if you keep your holding time within one hour each time, the risk of a mishap is 1 in 35,000. This risk is acceptable.
