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?
I thought about this, I think bitcoin will be replaced by alternative altcoin but it's not Ethereum or Bitcoin Cash. In the future I think there will be a altcoin replace bitcoin.
