I’m not sure if you intended on having actual replies to your comment; actually I’m unsure of what your intention was when writing your comment at all. But to make a small distinction with what you said referring to crypto [blockchains, cryptocurrencies], the scams you’re referring to are mostly enabled by centralized currency exchanges (like Coinbase, Bitmart, etc) and trading assets on an actual blockchain should be far safer. The problem with using blockchain in this way is that it has a much higher barrier to entry, needing to know a lot more about your particular blockchain to participate with transactions outside of those centralized exchanges. Coinbase and the like make interacting with blockchain and their underlying currencies much simpler, but they also kind of defeat the whole purpose of having a decentralized ledger.
