Bitcoin Dominance Crashed on Paper — but the Altcoins Needed for a Party Never Arrived

TradingView’s Bitcoin dominance chart plunged from 60% to 24% on Monday because its crypto market total exceeded $6 trillion, falsely suggesting an imminent altcoin rally. Bitcoin itself did not move, while CoinMarketCap continued to report Bitcoin dominance at 60.3%.

TradingView calculates dominance by dividing Bitcoin’s value by a market total built from the 125 largest coins, according to its support page. The sudden increase in that total mechanically reduced Bitcoin’s displayed share, with the chart reaching 24.12%, down 60.30%. A post accompanying the chart asked, “Are the parameters glitched, or are market makers hinting at a MASSIVE altseason?” Crypto Rover remarked.

Other measures did not confirm an altcoin season. CoinMarketCap’s Altcoin Season Index stood at 40 out of 100, while CoinGlass reported 44. The index tracks how many of the top 100 coins outperformed Bitcoin over 90 days, with a score of 75 required for an altcoin season. BeInCrypto reported a year ago that Bitcoin dominance had passed 60% while fewer than 5% of altcoins beat Bitcoin.

TradingView had not publicly explained Monday’s error at the time of writing. Its help page says a large coin entering or leaving its top 125 can jolt the total, although that explanation for this incident remained unconfirmed, and it also states that major spikes can be smoothed out manually.

The apparent crash nevertheless drew speculation on social media.

The indices designed to identify broad altcoin strength did not indicate that such a rally had begun.
