Guys i need help! Cant find anything on this... if im trading and sell a coin but want to buy back in 10 days later. Do you leave that money in btc or eth? For instance if i make $1000 on a coin but want to rebuy in when it dips, how to you keep that money safe, without risking btc drop in value while you wait to buy back in? I heard about keeping it in USDT but they've been involved with some controversy lately. Thanks!
