the reason why crypto is dangerous is because it's very, very easy to get a piece of it. it is open to anyone and you can buy for just a dollar. this drives up price unlike anything out there. yes anything can be a store of value with enough people believing in it. bitcoin succeeded in generating large enough followers to drive up its price like crazy. if it continues, it will suck up capital from all other asset classes - which in turn create a huge global inflation. losing value is one problem and the global inflation crypto will bring, if left unregulated, is another problem.
