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.
