So I think the real crypto users are just a few millions. The technology is still too complex for ordinary users and mass adoption. You grandma could use a CC, but crypto? Or even your parents?
If you think about it, it's not that complex. All you need to do in most situations is copy + paste. It's certainly a little more inconvenient than the technology we're used to, but I wouldn't say it's
complex. Even a grandma who could operate a computer should be able to get the hang of sending and receiving transactions in just a few hours.
But yeah, that being said, the current generation and the succeeding ones should fare far better, and is more likely to be attracted to Bitcoin. Maybe all it really takes is time.
