My experience is very similar to yours. I was never able to "hodl" my hard earned BTC, because I needed money for living, and I cashed out a lot at $3k-$4k, and what is even more painful, I cashed out more than 0.5 BTC, all I had at the time, when the price was below $300 in 2015. Did I really need that money, $150, back then? Yes I did.

So, I know how you feel, mate, but let's not blame anyone. Let's study hard so that we could earn good money with our knowledge, without relying on the rate of highly volatile assets.
