I think it would be best if you are going to wait first for now, the price of bitcoin has already recovered but not yet to the fullest but still it wouldn't be a good idea to buy bitcoin right now. Selling can be a good thing, it can be considered as a good strategy knowing that if ever the price falls down back again, you will not feel any regret for you have already sold your bitcoin before the price fell down. We should be careful on making decision on such things, always monitor the changes in the price to know what's best to do.
