It's really an arms race between the people and the governments. Technology is like nuclear energy or just like AI. You can use it for anything. Only way we can make sure crypto is used for good is to make it impossible for the governments to do anything about it. They may persecute 1% of the population. They may even persecute 10% of the population. They will have a tough time with 25% of the population and they will never ever subdue 50% of the population without some alien mind control trick or some super weapon.
I hear lots of Dash adoption news regarding Venezuela (http://www.discoverdash.com/) I think this is the right thing to do. Crypto can save a lot of people from a lot of trouble. But people need to adopt using cheap, fast, private crypto like Dash, PIVX etc.
The devs should also make things easier to use for common people. Most mobile wallets are now in a good condition. If you can bring lots of people from Venezuela to STEEM, it'd be a great thing. Current prices are very low and little bits you make today can end up being worth a lot.
