Why you should focus more on saving bitcoin than selling it because bitcoin price is still increasing, and you can make more income in it. If you are selling now your bitcoin for no reason, Im sure after a week or month you will be disappointed. Even bitcoin price is unstable most of the time it is increasing, and you can gain profit.
Yes, I think short-term investments will be insured when investing in bitcoin, because the bitcoin market is volatile, and not the longer it is, the more valuable it is.
