ETH accumulation fluctuates
However, BlackRock’s ETH accumulation has lost some steam towards the end of Q3, compared to BTC. For BTC, it ramped up its stash from 698K BTC to over 740K, about 6% surge in the past two months.

However, it remains to be seen how the potential staking approval could improve the overall demand for ETH ETFs.
That said, Spot BTC ETFs remain the keyholders of BTC. As of September, this category of investors controls about 7% (1.4 million) of BTC’s total 21 million supply of coins.
In contrast, corporate treasuries, led by Strategy (formerly MicroStrategy), command 4.6% (1 million BTC) of the overall supply.
