Could this be happening? For example with an institution like BlackRock?

Controlling Bitcoin Price within a Range Using Spot ETFs & Options?

1. Spot ETFs:

   - Buy to raise price: Accumulate Bitcoin in the ETF to reduce market supply and drive up prices.
   - Sell to lower price: Distribute Bitcoin to increase supply and put downward pressure on prices.
   - Issuance/redemption: Redeem ETF shares to remove Bitcoin from circulation (raising prices) or issue more shares to add supply (lowering prices).

2. Options:

   - Call options to push price up: Buy deep in-the-money calls, forcing market makers to buy Bitcoin to hedge, creating upward pressure.
   - Put options to push price down: Buy deep in-the-money puts, forcing market makers to sell Bitcoin to hedge, driving the price down.
   - Short calls/puts: Selling calls adds downward pressure, while selling puts adds upward pressure.

3. Maintaining price range:

   - Upper limit: Near the upper limit, sell Bitcoin from the ETF and buy puts or sell calls to prevent further price rise.
   - Lower limit: Near the lower limit, buy Bitcoin in the ETF and buy calls or sell puts to push the price up.

4. Market sentiment: Large options trades influence market sentiment, driving participants to follow your price direction.

5. Hedging and rollovers: Continuously roll over options contracts and hedge positions to sustain control over the price range.
