I think one of the main reasons that these 3rd world countries are investing so heavily into BTC is because of their value in currency. Bitcoin's value surpasses the currency value of their own country and with a weak government, they turn to BTC.
This of course is only my thought, and you may think I'm spilling bullshit. But almost everyone that invests in BTC right is in hopes that it will generate a 100x return and make them rich in the near future.
Lol! what are you babbling about? Bitcoin is already worth 11000 dollars! It has kicked the dollar in its ass already. So how come it won't be worth more than their local currency? Also *weak Government has nothing to do with it.
As for your second part, i disagree. People are not investing in bitcoin because it will make them rich, instead they are investing in bitcoin because it is the currency of future.
Actually in third world countries there is no job and the economy situation is not so good there and people have no good food to eat and education system is also very bad so bitcoin bring revaluation is these country because bitcoin is providing such a good opportunity for income and people are taking a very good advantage from it and some of them have changed their life just because of bitcoin and they wish that bitcoin will be legal soon in their country.
