In my opinion, 40% is the very small amount, I think that if there is only 40 percent, then you have to leave it. On the other hand, 200% increased in value is a big opportunity to get much profit. If the project pumped, then it's bad decision to wait for the top, it is worth sell, dividing into several parts. We should always think wisely in terms of profit because bitcoin and altcoin are very volatile and unpredictable in condition.
