BlackRock's new interest-bearing Bitcoin is essentially the same as OKX's Dual Investment product. BITA holds Bitcoin, current price is $60K, and sells 'call options' every month to collect money: the buyer has the right to buy the Bitcoin at $66K. If Bitcoin doesn't go above $66K, the money is easy profit, distributed monthly as 'interest' of 8–12%. If Bitcoin surges to $80K, you still have to sell it at $66K, and you miss out on the excess gains. Perfect for @saylor to use for selling Bitcoin
