Hi HN,Since Binance being the worlds biggest exchange for cryptocurrencies is now under investigation from almost every regulator worldwide it got me thinking about all 'crypto' industry as a whole.I've also seen many crypto detractors call for them to be banned, shut down, due to scams, ransomware, fraud, pump & dump schemes, etc.Is it possible to completely ban or destroy cryptocurrencies completely?I'm not talking about the theoretical case. I mean practically, is this in any way possible at all?
