In a bull market, don't easily switch positions; the coins you hold will rise. Manage your hands well and don't act rashly!
What you need to do is not to switch positions upon seeing a rising coin, but to hold tightly onto those that haven't risen. Those who hoarded coins during the bear market and weren't left behind should be reaping the rewards now.
Buy when no one cares. Do not doubt this; it's an unchangeable rule. If you can accept the worst outcome of losing everything, then no one can hurt you, as long as you didn't buy a failing coin due to bad luck, it will definitely rise.
Trading coins is a test of human nature. Human nature thinks that the major coin is too expensive during a bear market and feels it can't rise several times, then turns to buy altcoins. When the major coin skyrockets, they start regretting not investing all in the major coin and question the altcoin season. Later, when the altcoins start selling, various altcoins dance wildly...
If you want to get rich from trading coins, you must understand human nature and even go against it. No one can succeed in investing casually; even the simplest act of holding without moving is something very few can persist in for four years.
Which will rise next? Which will fall? Only heaven knows, but definitely don't switch back and forth, and especially don't chase highs or sell low—it's a big taboo!
Investment requires a certain level of discipline. Otherwise, you will be ruthlessly squeezed by the market.
