“By Lee’s personal logic, if utility is NOT going up, then ETH is in a loss of life spiral,” the report stated. “That is precisely what we imagine is going on.”
The quick thesis additionally focused BitMine (BMNR), one of many largest company consumers of ether.
Since July, the corporate has accrued roughly 4.4 million ETH as a part of its treasury technique. With ether costs down considerably from current highs, these holdings are estimated to be 45% underwater, with BitMine sitting on roughly $7.4 billion in unrealized losses, DropsTab information reveals.
