This hypothetical event has its own name in the community: the Flippening. Ethereum has closed the gap with Bitcoin multiple times, particularly during DeFi summers and NFT booms when Ethereum's ecosystem was generating enormous fee revenue. The argument for it eventually happening rests on ETH's expanding use cases and deflationary supply dynamics. The argument against is that Bitcoin's brand recognition as digital gold has proven remarkably durable, and institutional products like Bitcoin ETFs continue to bring new capital specifically to BTC. Whether it happens or not, tracking the BTC/ETH ratio on YoloRates gives you a real-time read on how this long-running competition is evolving.
