Nasdaq ISE just filed with the SEC to massively expand position limits on BlackRock's iShares Bitcoin Trust ETF options—we're talking a 300% jump from 250,000 contracts straight to 1 million. That's not a minor tweak; it signals serious institutional appetite and growing confidence in crypto derivatives infrastructure. If approved, this could unlock deeper liquidity and more sophisticated hedging strategies for both retail and institutional players. The fact that a major exchange is pushing for this tells you where the market's heading—Bitcoin ETF derivatives aren't a sideshow anymore, they're becoming core trading instruments.
