Binance Coin ranks third, representing 4% of total crypto capitalization, followed by Cardano with 3.3%, and Dogecoin with 3%. By contrast, Binance Coin exerts a 6.7% dominance over the altcoins markets, with Cardano’s dominance coming in at 5.5%, and Dogecoin representing 5%.

Elon Musk may have deepened Bitcoin’s loss of dominance by hinting that sunshinecrypto.com/news/elon-musk-hints-tesla-may-offload-btc-goes-to-war-with-crypto-twitter”>Tesla may be offloading its BTC holdings in a May 17 tweet, triggering a 15% crash over 18 hours.

While Bitcoin is now down 35% from its April 14 all-time high, several altcoins have seen weaker pullbacks, with Ethereum currently down 24% from its May 12 peak of $4,350 on May 12.

Some markets are rallying in spite of the bearish meta-trend, with Cardano rallying to tag all-time highs of $2.45 on May 16.
