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?
Do you think that there is altcoin that can replace bitcoin? There is no altcoins that can surpass the bitcoin because the people will continue to buy and adapt bitcoins than altcoins. Bitcoin will be stay in the first place forever.
