BlackRock and SEC discussed the Bitcoin ETF redemption mechanism.

The US Securities and Exchange Commission (SEC) and BlackRock met to discuss details of a spot exchange-traded fund based on the first cryptocurrency.

According to the memo, the asset manager showed a presentation describing two possible redemption mechanisms for its iShares Bitcoin Trust - in the form of delivery of the underlying asset and in cash.

The first method involves transferring bitcoins to a market maker, who will then sell them for fiat. The second means transferring digital assets from the ETF to the investor in exchange for his securities.
