If Bitcoin became universal that also means we live in a decentralised economy.
That would be very great, i hope i'm still alive to experience the situation.
It seems to me that now if you go anywhere, where Bitcoin and the cryptocurrency are not banned, you can use it easily. Just have the Internet access.
yes indeed we can use bitcoin wherever and whenever, but we can only use it in the digital world and transact there with other people. maybe if it's used in the real world I don't know if anyone accepts it.
