How exactly does the money making process work? You buy some cryptocurrency for a certain price then sell it for a higher price and the difference is the money you've made? This would mean that the money you've made is still in terms of cryptocurrency. Then can that money be converted into the whatever kind of cash your country uses? How does it work?
Depends on the Country if there is a local exchange for BTC to their local currency but if there's none, there are other ways to cash out you BTC since USD is acceptable world wide. There are exchange sites out there that accepts BTC to be converted to USD, then USD to Western Union, Money Gram or Paypal.
