Cash is widely used for nonscammy purposes and I had plenty of good contacts with it.

My sole contact with cryptocurrencies is endless spam in mailbox, endless scam attempts in communities that I moderate and information about ICO and other scams. And <s>investments</s> gambling. And very rare cases of cryptocurrencies being useful for something.

And repeated info about being utter failure for payments. For comparison cash/credit card payment is done within 20 seconds for cc and within minute for cash. Both at cost of below 0.01 $ for payment.

Not taking sides here, just to nitpick that payment settlement takes a lot longer than that with credit card. It's like calling a bitcoin transfer with 0 confirmations "done", and which case it's actually faster than credit cards.
