Ethereum has been outperforming Bitcoin recently and I thought this would mean Bitcoin’s dominance would be declining, but CoinMarketCap and TradingView show that it has not changed very significantly. Altcoins are starting to look bullish, but this is mostly a result of BTC and ETH pumping. I don’t expect to see much of a rotation, but projects with solid fundamentals will keep performing well as long as institutions keep pumping capital into the crypto market.
The main reason why you don't see the significant change in Bitcoin.D is that because Bitcoin is also pumping. Remember this, BTC.D will decrease significantly only if Bitcoin doin sideways while alts pumping. That's totally different with the current condition. It's because Bitcoin is keep pushing to break new ATH.
