Trading cryptocurrencies is a human game, so it's important to think from different perspectives. If you always find that prices drop when you buy and rise when you sell, you might want to try this method: when you want to chase a high price to enter the market, assume you already have this stock and think about whether you would sell it; if you would, then there's no need to chase the high price. When you want to cut losses and exit the market, assume you don't have this stock and think about whether you would buy at the bottom; if you would, then there's no need to cut losses. Although this method cannot guarantee that every operation will be correct, you have learned an important strategy in the stock market: thinking from different perspectives.
