Not going to happen. As bitcoin gets more expensive, altcoins will provide the supply needed for the utility of bitcoin (doing business) which will reduce the demand and thus price of bitcoin.
Newcomers to crypto-currency aren't going to want to be part of a system where a select few have incredible wealth, hence why they will opt for altcoins instead of bitcoin.
Whats the point? It seems the concept of Bitcoin divisible a lot is not grasped by most people when big ass prices are predicted or proposed as hypothetical scenareos. If you can divice a bitcoin by 0.0000001 times, then whats the problem?
