That's the truth about crypto - No matter the amount of conviction/belief and no matter the amount of understanding of the blockchain technology, I think that some people are just not meant for this. The volatility of this market is not just a roller coaster but it is crazy in a lot of sense.
That being said, I will also say that some people are just actually built for this. But I also feel that even if one is either side of the spectrum of 'whether they have the stomach for it or not', they can still participate. For this to happen, one probably needs to keep in check the amount or percentage of what they are willing to invest.
For me I went all in around November-December of 2017 and right now its mostly bags that I hold. Nevertheless, my technical background helps to understand the technology involved ..... at least to some extent. On the other hand I also know that although I put in all the money that I had, it was not a life chaining amount by any means, and this factor is perhaps the one that has allowed me to keep my perspective objective.
