* The rich people could earn more in investing bitcoin while poor people could lose more. (vice versa the rich people may lose more and poor people can earn more)
What? Instead, Bitcoin investment allows people with a small amount of money can try to earn money as well. It is much different from the conventional investment, there are complicated requirements and you should have much money to join. Why don't you compare with invest in Forex? You deny the fact that Bitcoin makes everybody able to join even if you are a poor man. You can trade or invest even only have a small amount of money.
* the use of bitcoin to travel spending outside in the country is more like selling your country asset and that could destroy the economy of that certain country.
How can? Is the money I got from trading or investing in Bitcoin basically the money from my country? Or it is the money of my government?
No, the money got from trading or investing in Bitcoin is from all places in this world, it is global. Please open your mind and your eyes!!
