Well, it's a novel way to bash on BTC, I'll give you that. I mean this in the least hostile way, but if you really don't believe in BTC or any crypto then why spend time in a bitcoin/crypto forum? I am truly curious as to the answer. I personally find it hard to believe that the so called haters are all here out of the kindness of their hearts to try and warn people off losing their funds.
I am, I know someone that does nothing else than go on about btc all day, he doesn't have a lot of money but he believes one day he'll be a millionaire so he doesn't work.
I know of others who are similar, the sooner all crypto dies the better.
Well why not spend your time and energy trying to convince him to do different with his money instead of using it here? I know you may feel as if it is your moral responsibility but all of us are grown adults and we are capable of making our own decisions. At the same time we are responsible for dealing with the consequences of those decisions. If crypto does die (as per your wishes) then we are the ones that have to continue to live and enjoy our lives following that.
