According to the source, Bitcoin's late-September rally pushed the overall crypto market into positive monthly territory, with BTC leading performance for September. The source adds that most altcoins lagged versus BTC, indicating relative underperformance in altcoin markets and a narrow breadth rally centered on large-cap Bitcoin.

According to @rovercrc, BTC has already rallied and ETH is currently rising, and he expects altcoins to move next as the crypto market cycle repeats, source: @rovercrc on X. For confirmation, traders commonly watch a sustained decline in Bitcoin dominance BTC.D and a rising ETHBTC pair, which are associated with phases when altcoins outperform, source: Binance Academy. If BTC dominance continues to rise, altcoins typically lag on a relative basis, source: Binance Academy.

According to Michaël van de Poppe (@CryptoMichNL), recent market action shows gold prices breaking downward while Bitcoin (BTC) and altcoins are moving upward, indicating a potential start to a new crypto bull market. Poppe notes that a further gold drop below $3,325 would confirm the erasure of the uptrend and signal deeper downside, which could further fuel risk-on sentiment and capital inflows into cryptocurrencies. Traders are advised to monitor gold’s support levels and crypto price action closely for confirmation of sustained momentum. (Source: @CryptoMichNL, Twitter, June 20, 2025)
