The miner's self-mining hashrate rose to 79.9 EH/s and production was up about 249 percent from a year earlier, but its bitcoin balance ended the month at 61 coins, against 257 a month earlier and 1,934 a year ago. The company's own footnote says the figure counts coins pledged as collateral, which rules out one explanation for the drop.
The Ways and Means Committee marked up H.R. 10357 on Wednesday morning, a day after the CLARITY Act stalled in the Senate. The bill waives tax on network fees of $10 or less from 2028, but settles only that staking and mining rewards are ordinary income, not when they are taxed.
