If btc is legally accepted in all countries then huge number of investors will increase. and the use of btc in various fields will increase.
what is your opinion about this?
well this is too much to handle when world wide adopt bitcoin as their legal currency maybe it will not only double the price it self maybe more than what you are expecting from it. as you can see if bitcoin can be use as a payment method by buying and paying some other bills etc. But in reality we had so called blind government that only wants fiat which they can easily benefit from people or others that can make them more rich what a greedy nonsense.
