This is really important if you are concerned about the bitcoin price in the short run. Because of the ridiculous 1.5% management fee, there is going to be mass dumping of GBTC shares (which represent 600k+ bitcoin) and Grayscale as I understand it will then have to redeem large amounts of shares and sell the bitcoin representing those shares.
My guess is most of the GBTC holders will buy bitcoin or another ETF with lower fees, but there may be a time lag and some GBTC holders may not invest back into bitcoin at all. nostr:note1hchem5eyr8mtyngp0vre376vnkux54yct7al0wzc9v94pe7mahmsh4nelk
