I'm not a maximalist, I've seen the arguments, but I don't agree with the idea that all cryptocurrencies are a scam and can't ever be used as money. This is refusing competition from my point of view.
However, I decided to give up investing in crypto because I just don't want to be on the loser's side in the end. I want to put my money on something that I can forget about for like 10 years and then have a nice surprise when I finally remember I've bought it. I believe only Bitcoin is capable of doing that.
