The flippening will happen as Bitcoin has its technical issues and people just like to keep forking it.
Ether or Ripple appear to be good candidates.
People don't like Ripple because it caters to the banks. That may actually be a strength for price stability and for the normies to feel confident enough to start adopting crypto.
Remember there are about 7 billion normies so they could really drive up the price when the pile in.
I am a hodler but let's face it, guarding your private keys is a bit of a pain in the ass. It would be nice to have an account in a main stream bank that holds your crypto for you and guarantees you in case of a hack.
