BlackRock’s iShares Bitcoin Trust has had better months — in fact, every other month has been better.

After suffering its worst November on record, the world’s largest Bitcoin ETF is now staring down a six-week outflow streak that suggests investors are fleeing fast.

Once hailed as the ultimate bridge between Wall Street’s deep pockets and crypto’s boundless promise, BlackRock Inc.’s iShares Bitcoin Trust (IBIT) is suddenly looking more like a monument to fading enthusiasm.

More than $2.7 billion has been pulled from the fund in the five weeks through Nov. 28, with another $113 million yanked on Thursday, Dec. 4, alone, Bloomberg reports.
