Simple, i usually use the profit to re-invest it in other crypto.
If you look at the crypto market now, the downtrend of coins has started, bitcoin price now around $34k.
This is a good opportunity to buy and accumulate some top coins in the market, and hold them until we get a decent profit.
Lucky those who already saved up for this season to buy at dip, as much as possible when I trade and make some profits I try to left some usdt before buying again new coins or start placing my bets ageain for times like these that the market seems going more at dip. We may not sure up to how low it will take but we must take our chances since it may not go that dip again. It’s better also to take all the trades we do whether we used up already the profit or there is no profit at all especially if trading with different exchanges to monitor and update our plans base on current market situation.
