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 think for the future altcoin will also be able to rival the bitcoin glory because now it is very much altcoin that attract people one of them ethereum and nxt, so I'm sure both will be able to compete with bitcoin in the future .
