Actually, the fear of crypto misuse is because they do not understand and do not have knowledge about crypto technology. In fact, illegal activities are not only in crypto, there are also FIAT money. Maybe because of the decentralization of this system that makes them afraid that crypto will be misused.
Crypto is only used as a tool for illegal activities and basically crypto technology is decentralized and no one can extract it,
especially on Blockchain, transactions that will be permanently recorded and no one can delete them.
Don't blame the underlying technology, but of course see what projects are being developed.
Now when Bitcoin reaches a new ATH, many say that Bitcoin is a replacement for Fiat and such,
whereas previously many were skeptical of Bitcoin and only considered Bitcoin a scam and would end up with ZERO.
