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.
