Crypto is just another private currency. Of which there have been many. And most folks have even used some of them. S&H green stamps, camel bucks, credit card points. It’s a long long list. The only real difference for crypto is that is uses the internet to be faster and less trackable. It is neither a dream nor a nightmare. It is simply there.
“Crypto is just another private currency.”
The millions of people all over the world who have lost their life savings to the scam would tend to disagree with you.
I don’t know anybody who went broke collecting green stamps.
