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.
this is the way we will growth our crypto balance massively. take profits and take our initial balance in our investment and let the rest running. this is simplest way that used by alot investors in crypto market, sometimes taking our initial balance to avoid big dump happen , eventhough it happen we safe our money yet. for long term current price was good enough if we start buying with small amount, maybe pump will come soon.
