I find that many people have a habit of holding ETH, BTC, altcoin for a long time and always hoping that it will rise again. If you are a trader, you will lose money for that. Set small target and sell them when you see profits. I only need 3-5% profit when trading.
If you see the market going down, stop loss before it's too late. You may lose 5-10% of the capital but when the market goes down you can buy more btc, eth when you hold btc, eth, altcoin.
Sell all ETH, BTC into Stable Coin when the market goes down
maybe to get a small profit when market prices experience a slight increase can only be felt by daily traders, in contrast to long-term swords they certainly can take advantage of market conditions that are always decreasing by buying more potential coins to hold, so they can get bigger profits and of course it can minimize the risk of losses because they believe that some of the coins they have will increase in value in the future
