i do this question because i´ve read in this website issues with bitcoin, slow mining process, high fees, etc. and i´ve read too good reviews of some altcoins, ethereum (smart contracts), ripple (for transfers between banks), dash and nem. these altcoins called 2.0. could bitcoin become just in future virtual gold reserved to companies and rich people?
Perhaps yes, because one of the example of it was Sweden, were they are planning to extinct their paper money/fiat to their country for the coming 2023, meaning they will use digital and credit card as payment or to buy anything.
