I think that selling when there's profit (at least 2x) is reasonable no matter what happens next. However, the market is still generally down with a hardly distinct tendency upwards. It is rather stable but still vulnerable to bad news. In fact, there weren't any recently and that might be the reason we don't see the prices going down, you know.
Op, if you're know just in zero or something close to that - keep looking at the prices and sell when it decreases about 5% within a day. You can buy it when it's down later again. But for now it seems better to let your funds grow by hodling.
