Bitcoin mining company MARA just bought 10,000 BTC for $66.7 million, and BlackRock launched the covered call ETF BITA on the same day. Looking at these two events together, institutional capital is diverging: on one side, miners are using cash flow to directly accumulate coins, betting on spot appreciation; on the other side, Wall Street is packaging strategies with options, earning volatility premiums rather than directional gains.

MARA’s increased holdings are not an isolated case. Previously, BitMine’s holdings approached $10 billion, and miners have been accumulating during the bear market without pause. But BlackRock’s BITA strategy is more worth examining—it holds Bitcoin while selling call options, targeting an annualized return of 15-25%, with investors enjoying at least 70% of the upside gains. This indicates that traditional funds are beginning to accept Bitcoin as an underlying asset but prefer to manage tail risk with structured products.
Behind this divergence is a difference in the nature of the funds. Miner purchases are balance sheet actions, deeply tied to price cycles; whereas products like BITA target yield-seeking fixed income funds, with Bitcoin exposure being indirect and limited. When both types of capital flow into the market simultaneously, liquidity structures become more complex: spot buying comes from miners and long-term holders, while derivatives are hedged through options strategies, reducing some upside elasticity.
The risk is that the covered call strategy of BITA may underperform spot during a one-sided market rally, and while it can buffer some losses with premiums during downturns, it cannot fully hedge against principal loss. If Bitcoin enters a deep bear market, redemption pressures on these products could actually accelerate selling. The leverage risk for miners is also significant—MARA’s increased holdings are funded by FalconX, and if the coin price falls below their cost basis, collateral liquidation could create a negative feedback loop.
The way institutional entry is becoming more refined, but the transparency of capital flows is actually decreasing.
