If you have that instinct inside you, then working on it for long-term goal is a good option.
Being optimistic added trust, from that everything turned into positive, it's very important not being move by any market downfall, it will only annoy you, keep your investment intact while waiting for your target goal, those who invested back in 2017 who still holding their assets are now enjoying. Bitcoin keeps bouncing it will depend from your perspectives.
These are the real things that we should be aiming at instead of selling but that is lost on so many people. Reality is that bitcoin could go down or up in small amounts in the short period, it could even have a big bear crash as well, there is really no reason to keep that going. However one thing is for sure, bitcoin will be going super high in the long run. Frankly I believe the same for ethereum as well.
So, I am working on getting 50% bitcoin, 40% ethereum and 10% junk coin portfolio, and I have been very decent at it, I used to have a lot more bitcoin and a lot less ethereum, now I am trying to exchange that but I believe that is going to help me in 10-20 years. Yet some people expect to get rich tonight, that is not going to happen it is not that easy and you will have to end up with a lot more drops before you can see 100k ever happening.
