Arthur Hayes, co-founder of BitMEX, predicts Bitcoin could double in value in the coming months due to tightening exchange supply and expanding liquidity. He also forecasts Ethereum reaching $10,000, while identifying altcoins like Pendle, EtherFi, and Ethena as having real demand and cash flow. Hayes suggests that the traditional four-year crypto cycle may still be relevant, with a potential market peak in late 2026 or early 2027. He emphasizes that high-quality tokens with genuine use cases are likely to outperform speculative assets in the next rally.
