Lesson 5 is one lesson most people have to learn the hard way, including myself. Doing okay now (made a lot and lost a lot). Sometimes though, you do have to cash out profits. I'm sure many people wish they would of cashed out when it was green candle mania. I've made some 100X gains, but I've also had some 100-1000X losses (CarVertical, anyone?). Long term, though, I think your right. Be optimistic, see the mid-to-long term picture, gain blockchain knowledge, and be patient.
