At this pace IBIT is going to surpass GBTC very shortly.
Well not taking into account their new mini ETF.
IBIT has close to $16 billion in assets currently.

The mini ETF will be interesting from GBTC to see how it impacts things.
I suspect much of that IBIT total is rotated funds from GBTC, but how much, impossible to know.
