I'm not sure the flippening would actually happen, but people will start speculating about it again for sure.
It's possible too. The ETH supply is growing a lot faster than the BTC supply, so overtaking BTC's market cap is getting easier and easier in terms of price. Market cap is such a dumb metric......
Do you hear what you are saying at all, and do you have your facts? I think you are just basing your judgment here on assumption because I have not seen any much growth in the community of Ethereum, it was of recent that someone even complained that Ethereum fee is getting far higher than bitcoin which is the leverage that they have had over Ethereum, but with the introduction of lighting network, people no longer complain of bitcoin transaction that much again, and everyone still prefers to receive their payment with bitcoin.
Since I have been in this market, all my payments and all my received money has all been through bitcoin, which I have never for once thought of Ethereum because even this bitcoin fee that some people are complaining about it not that much to me, you can never compare the payment of fee in our local bank to that of bitcoin.
