Everyone would like the bitcoin is accepted in all online and real stores and, as as mentioned in the title, what would happen if Bitcoin became a legal currency?
I think there's a large possibility that bitcoin would become legalized worldwide since the influence of it has been improving a lot since there are different ways to dessiminate the news about it already since technology has improved a lot lately. If ever bitcoin became legalized worldwide, it will surely end up being prioritized by many and it would surely bring great convenience to many which will attract more users and investors.
First of all, we need to find the interesting point of Bitcoin can attract the "normal" user, not only investor, trader are the user of Bitcoin if it can becomes one of currenecies for the world someday. Transaction fees is useful for global transfer money, but for national transaction, it is useless. The value is unstable with strong volatility everyday. Only two factors are enough to make Bitcoin can not become the best option for the normal user.
