Big “market plumbing” day: Nasdaq BX removed the 25k position/exercise caps for options on several spot BTC & ETH ETFs - SEC notice published Jan 21 and it’s effective immediately (SEC can still suspend within 60 days). Meanwhile Binance removed multiple spot trading pairs at 03:00 UTC (Jan 23) due to review factors like liquidity/volume. Context: wider derivatives rails + tighter spot pair hygiene can amplify headline-driven moves. Sources: SEC, Binance. #BTC #ETH #ETF #Binance
