The Bitcoin dominance is down to 67.5%, which is around one percent lower than what we had 24 hours back. And surprisingly it is not established altcoins such as Ethereum or Litecoin that is giving the biggest challenge to Bitcoin in its quest to dominate the cryptocurrency market. The coin which had the highest 24 hour price change (among the top 10) was Bitcoin Cash, which went up by 7%.
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.
Bitcoin always dominance in coinmarketcap because almost investor just looking with bitcoin as investment than altcoin, they have big interested with investing on bitcoin than altcoin. Bitcoin can give higher chance profit than altcoin although every day with several percent for earning profit with bitcoin investing, with altcoin maybe waiting for long time to get profit and big risk when altcoin price down.
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.
