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.
In my opinion doing re-investment is indeed very appropriate but you must know that not all coins can make a profit quickly, when you look at the condition of the exchange as it is today, it should be able to provide information that not always cryptocurrencies can provide a lot of profit, so you still have to be careful when investing in cryptocurrencies.
