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?
It would be possible at any aspect but for now it's only a bluff or a hoax , cause as you can see now bitcoin is expanding and becoming larger and larger by the suddenly increase of bitcoin last year many people notice it and it become popular. So as the ethereum and the ripple , but still depend so for me it can't , bitcoin cannot be replaced by another crypto or coins , he's still the king though.
