Bitcoins is a good source of income for those who can't find a job. If this would be introduced to other countries other people would have the opportunity to earn even while at home thus making them more capable of having a better life.
This is totally right point that bitcoin has not reached to all the people around the globe due to some interference of the governments or the banks or the propaganda, but the thing is that bitcoin can only turn the lives of people to better mode once it will be available to everyone without the fear of doing some illegal activity. Right now the governments of third world countries have turned their blind eye towards this issue, which means that the people will be held accountable if the governments start discussing it today, so there is a bit of insecurity among those people.
Exactly, the government want to make the cryptocurrency user accept the risk of the price fluctuation in this field. They also remind everyone do not forget the ability of cryptocurrency to make the investor lose money. Profit is just available for those who are good investor, noob investor and newbie usually have loss.
