Iran and Venezuela would not have the crypto tool if it had not been for a free society in which they can operate. The fact they were tyrannical oppressive regimes before crypto came along is besides the point. They have them now and are proving useful for their citizens. I don't know how you say they haven't helped "much". I've heard they are proving very useful. Maybe not in overthrowing the regime, but at least in helping them to survive.

It's definitely useful in the hyperinflation environments happening in those countries.
