Whenever the price of Bitcoin is rising, it is a normal thing on the market to see the prices of alts going down. This is because everyone would be selling their altcoins to invest the proceeds in Bitcoin because they see BTC as the only reliable coin in the crypto space
and if we have enough profit then we sell it quickly, because waiting for a long time is not necessarily you can get big profits, so fast you have to sell it before it's too late, the market drops dramatically.
everyone has a different strategy and what they think is good so they are finished, but we have to be careful not to get stuck.
I was a little late in selling my altcoin so the results I got really couldn't be maximized. So, do not waste time when you are at the top, regardless of the profits to be earned, if the prediction is right, then you will not regret it, and immediately buy it back at a lower price. As you say that everyone must have a different strategy, what needs to be considered is not to be a greedy person.
