It's useless if the price goes up but the share doesn't!
In this situation, for a novice,
it seems a bit helpless.
I'm afraid of standing guard if I chase in,
and I'm afraid that the price will go up and the share will be more expensive if I withdraw.
I still have to stop profit and change to U,
and cover the position at any time, or ambush other coins.
As for transaction costs, it's not a big problem.
Withdraw 15-20%,
even if you withdraw 10%, you can cover it.
