Traders needs their balance to grow in usdt and not in any altcoins unless you are only trading to increase the amount of that altcoins that you want to have in preparation for the bull market. When I take my profits from my trade, I keep them in usdt because that is what my goals are for as I want to grow my fiats balance to the extent I would not have to trade to have money to use. I am also investing in Bitcoin but I am doing that not when I am trading. Taking profits is very important in trading and that is what I always do. I do not think we have to only trade the no risky coin like memecoins, I think we should trade every cryptocurrency that we can make profits from.and make that profits because every coin can be used to make profits.
