Both Ethereum and Litecoin have not managed to breach the major resistance levels. Ethereum is still trading at 0.0198 BTC per coin, while Litecoin is trading at 0.0063 BTC per coin. XRP is performing well, and has reached a price of 3222 Sat. Out of these three coins, only XRP has managed to move forward during the last 1-2 months. Others have all lost their value against BTC.
I agree with your opinion that bitcoin always dominates the market. I think it's all because Bitcoin is still a favorite coin that can benefit investors. maybe investors assume that bitcoin has a more beautiful future than altcoin. and maybe also investors assume that altcoin is a lot of rubbish, so they will prioritize choosing bitcoin over altcoin, because surely they assume that holding altcoin carries a greater risk than bitcoin.
