There is no such thing as the "Flippening".
For now, I agree ... but that could change in the distant future. We don't know it. My point was that e.g. if Ethereum (or any other altcoin that F2Pool doesn't support) manages to get 40-50% of BTC's market cap F2Pool could change their opinion and support Segwit to ensure BTC conserves its leadership. (At the moment ETH is on 20% of BTC's marketcap so it looks not completely impossible, although I wouldn't bet on it).
Stop with this doomsday propaganda. There is a possibility in the distant future that an asteroid wipes us all. We don't make decision today just based on this remote possibility. No altcoin comes near to anything what Bitcoin offers. The top players right now (besides Monero and LTC) are all scam coins (ETH, DASH, Ripple, et. al.). A centralized, banker and corporation funded coin like ETH or a system (backed by the same groups) such as Ripple can easily overthrow the Bitcoin market cap within a week.
Moving on:
