Does anyone know how many bitcoin GBTC holds? Can they prove that they have that amount? Is it in line with the fund's market cap?
As of December 31st, it held 0.09181239 BTC per share. We're about to have a stock split, though, happening tomorrow, so this figure will no longer be accurate per share, but the amount of BTC will still be proportional to this after the 1 to 91 stock split.
