For altcoins, buy low and sell high, and you will make a profit. Although this statement is correct, it does not go for all coins. Some people think that when the market rebounds, their altcoins will rise with it. But the result was leaving the market at a loss.
So choose wisely and follow up the project. See what their developers are doing, or just hiding behind the prevailing saying.
This has been discussed many times and we all now, not all project are good and most of them is just a hype project, look at the new meme tokens before, they are slowly dying and some of them turn into scam so for me, not all altcoins are worth to hold so if you have a chance to take profit, do it as early as possible or else you’ll be trap on that.
