that right ! i think so ! Bitcon is not money of the world in future !
In my opinion, it is not impossible. But to become a global currency, bitcoin will need changes and solve many problems in the future. Decentralized supply and legitimacy. The current volatility is transforming bitcoin into a highly profitable investment. But I do not think that is the goal of bitcoin.
Bitcoin is already changed enough and even for me it is already a global currency that it is highly acceptable now and we can use it anywhere in the world, almost every market has the exchangers that you can convert your bitcoin into fiat and use it to buy goods, now bitcoin is almost adopted worldwide as currency, our government is also trying to accept the importance of bitcoin as currency now.
