It depends on your idea of profitable. If you can not hold on to it anymore, you can cash in on it and invest it into another coins. One thing I do believe is, there are coins out there with real value and could help in this kind of situations as investments. You can trade your Bitcoin or ETH for some of these coins. Just do your research on which worth it, and you are good to go. Holding on to the coins is still profitable, only that it is not so in few weeks, but,  months.
