He states that the ETH/BTC pair bottomed when the yuan bottomed in April, indicating a historical correlation between CNY inflection points and ETH relative performance, source: Michal van de Poppe on X, Dec 24, 2025. He expects that as CNY breaks upwards, ETH could see a strong upside breakout, making ETH price action a potential beneficiary if the correlation holds, source: Michal van de Poppe on X, Dec 24, 2025.

According to @AltcoinDaily, Tom Lee said Bitcoin (BTC) and Ethereum (ETH) are entering a supercycle because the business cycle is turning up with ISM above 50, adding that new highs could arrive early, like in January (source: Altcoin Daily on X, Dec 11, 2025). For trading, ISM Purchasing Managers’ Index readings above 50 indicate economic expansion and are commonly associated with improving risk appetite; monitoring upcoming ISM PMI releases may help time BTC and ETH momentum shifts (source: Institute for Supply Management).
