I think you should be patient by hodling your bitcoin or any other tokens rather than selling it in the wrong time. Investing bitcoin is for long run, you should be patient even if you can see the market that the price is falling down because we all know that it will rise again. And for the altcoins, there are altcoins that can be in the long run but most of it is for short term only. If you want to earn much more bigger than what you are earning now, then i suggest you to hold your bitcoins for long term investment.
