I don't believe in crypto either because it's current value is solely derived on how much you can exchange it for real money. Outside of a few edge cases, nobody buys anything with crypto outside of the black market.
I'm sure crypto is a great solution to some finance problems related to centralized banking that I'm too lazy or dumb to care about, but I look at the energy consumption to calculate these massive chains for little tangible benefit, and the scammers and hypemen who are profiting off of other people's hopes and desires to get rich quick on the next big boom, and I can't help but feel like it's an actively harmful element of society. At the very least, whatever regulations are currently in place that are attempting to reign in crypto are insufficient at reducing harm.
