It's the usefulness
Cryptocurrency is useful only for illegal transactions such as buying drugs or weapons, money laundering and ransomware payments to organised crime. Society doesn't need cryptocurrencies or their users. Banks around the World should be forbidden to trade Bitcoin, Etherium, Litecoin, Zcash, Dash, Ripple and others like them for cash. Its novelty would fade fast if it couldn't be converted into real currency. As a bonus, criminal gangs would lose the fortunes they have tucked away in digital wallets, which would be a great outcome for the common good.
