A few years ago, “the flippening” was a hot topic - every altcoin bull run brought new headlines claiming ETH (or some other chain-of-the-month) was about to overtake Bitcoin in market cap, utility, or narrative.
Fast forward to today: ETH/BTC pair is in a multi-year downtrend, alt narratives are fading, and Bitcoin dominance is back above 60%. The ecosystem feels quiet. No more hype, no more retail. Altcoins aren’t leading anymore — they’re trailing.
Was the "flippening" idea always a meme born from bull market euphoria? Or is there still a real possibility that some crypto asset could overtake BTC in the long run - either in market cap or relevance?

There's always the probability and this shouldnt be that making up some conclusion since no one knows on what the future looks like. Bitcoin might be that father of all crypto but it doesnt mean that it wouldnt be that replaced into that top spot. The only thing that mattes here is about recognition and adoption on which it would be that totally depending or basing up into the community itself. If there would be some flippening then this do simply means that there's much more better with Bitcoin but honestly there are tons of altcoins which performs better than Bitcoin but since it was the origin of crypto and be the first then there's no doubt that it do get that extreme support and investment by the community.
