I wouldn't say crypto is responsible for the world's greatest scams, but it is a growing trend whenever there is new cryptocurrencies introduced. There is a lot of scams within the crypto scene, and it will continue to happen unless there's some way to vet these new currencies, which at the rate things are going, I doubt that would ever happen. We've seen too many cryptos start up and the creators use it to get money and then when the market fails, they bounce with their earnings and leave the people who invested in the dust.
It's going to be responsible for more scams in the future, that is a given. You just need to be responsible as an investor and research any crypto you are interested in, because at this point, I wouldn't trust most new cryptocurrencies right out of the gate.
