The ETF will own the BTC not BR. The investors in the ETF control the buying and selling. BTC ETF’s, if successful, will pull in a large amount of passive money and potentially create a large pool of long-term holdings, increasing the floor and reducing vol, IMO. I see the value of BTC for me and self-custody. Many will see the value for others but not themselves and will happily allocate capital accordingly via ETF’s.
