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 it could be bitcoin replaced with other crypto currency, especially if other crypto currency is better than bitcoin. However, for now the prima donna in the crypto world is bitcoin, since bitcoin is the oldest crypto currency and invests heavily in bitcoin, but someday maybe people will switch to other crypto currencies if better than bitcoin.
