The problem with crypto is the same problem as always. Bad humans come along and destroy what could have been a good thing in an attempt to fill their bottomless empty pit of greed at the expense of everyone and everything else. Happens every time any human(s) try to create something that's meant to be beneficial for everyone - along come a few scammy ass-hats who decide they're gonna ruin it for everyone (by weaponizing it, turning it into a scam, or what-have-you), and inevitably a whole bunch more scammy ass-hats always gotta jump on that same bandwagon, increasing the momentum of the downfall. Yay, humans!
