I was just listening to the part of @gladstein's book about Cuba. Hard to know what % are using it if they’re maintaining good opsec, but there are quite a few. I have mad respect for Cubans who have resisted their authoritarian leaders, given the severe penalties for doing so. 

 you do what you have to do when there is no other choice, i hope we don't get there but people are awesome when cornered 

 some but not a huge amount from last I read, internet/phone availability isn't as high as everywhere else:

What I mean is on the island you use everything available to you whether it gets you in hot water or not... some examples:

side businesses, illegal but most people tried to have them (selling tupperware, selling stuff other people can send you from outside, 

growing food, illegal, people tried to have gardens/connections/animals

using dollars: on and off illegal, everyone tried to get their hands on dollars at all times

outside news, illegal, everyone pirated satellite feeds from neighbors or used government accounts to try to access internet

This is why the more freedom tools we have the better off we will be. In case of censorship and government overreach we can continue to fight back and get creative as a people. Do I hope Bitcoin just wins and everyone uses it and the future is awesome, sure, but I lean less likely.
