What if some decided to never return? I believe some people may not be able to have access to their money again all because they are not in the country no more. What I am just trying to pinpoint is the fact that Bitcoin and other legit cryptocurrencies can offer convenience, you have nothing to be worried about.
It is very possible to get access to your bank account from anywhere in the world via Mastered card and Visa card make we no condemn bank just because some of their customers are just stupid, these cards were implanted to solve problems like this one. Most of the Afghan wey get Mastered or Visa still get access to their money while those ignorance. Bitcoin is the new freedom but Bitcoin still need local bank to function because you still need to convert local fiat to Bitcoin.
