Not so my friend. It all depends on how the strategy will be used even though the assets they have are Bitcoin and Ethereum. If the current price has reached the profit target, then choosing not to keep or choosing to sell can also be the right strategy to do.
This has indeed become a benchmark for everyone when they have seen good profits in the assets they have owned for a long time even though after selling them they will also expect another market correction to be able to enter optimally when the coin price starts to low.
