Bitcoin price starts to fall from the beginning of the year, and it's no bad we keep our bitcoin. In the long term, the price of bitcoin is not like the last year, need to restore confidence to everyone. If the bitcoin price goes down, I'm sure the price of the other coins is also down. If there are other alternative coins that are more profitable why not, but we should not choose the wrong ones. My advice is always update the development of cryptocurrency, so we know better what we should do.
