Per Thielen, buyers in Grayscale’s ETF, the Grayscale Bitcoin Belief (GBTC), switching to different low-fee choices will doubtless weigh over bitcoin’s value. Whereas Grayscale prices 1.5%, different asset managers like BlackRock cost 0.25%. GBTC, previously a close-ended belief, is among the largest bitcoin holders, with a coin stash of over $27 billion. GBTC shares started buying and selling in 2013 and have become redeemable on Jan. 11.
