What you have to do is to calculate the risks, so you can decide if those risks are worthful to be taken or not. Not every risks are worth to be taken, and as an example I can mention the largest part of altcoins' market, which is full of opportunities and risks, but still not worthful for a long term investor like you who have been holding since BTC was pricing 17,000$.

The possibility of gaining something valuable is what really matters when making an investment, and in order to understand that, you have to measure what are the chances of that possibility becoming true and what you are going to lose and its implications, if something doesn't happen as you firstly expected.

When the possibility is too low, don't put much expectation or hopes on it. Focus on solid and concrete projects for your life.
