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?
In time this is possible and probably likely, everything has their time at the top and is eventually replaced. Nothing can remain at the top for ever and bitcoin will be no different in this sense.
