> Well, the one good idea is using it as money The major component of crypto being distributed consensus it has absolutely no way to work with external world, therefore it can only work with blockchain-borne stuff. The only thing dreamed up yet are cryptotokens. Since blockchains have no way to interact with external world it can only be used to exchange cryptotokens between wallets - there is no way to ensure that other side of the transaction involving anything else but cryptotokens is upheld. So it CANNOT be used as money by probably any sane definition of money. Crypto scams are natural consequence of this inherent property.
