Bitcoin mining company Riot Platforms had a "historic month" in June, boosting its hash rate by 50% and mining 255 Bitcoin (BTC), a near 20% increase from May. The firm's hash rate rose from 14.7 exahashes per second (EH/s) to 22 EH/s, surpassing its mid-year target of 21.4 EH/s. This makes Riot the second largest Bitcoin miner by hash rate, trailing only Marathon Digital. The firm held all Bitcoin mined in June, bringing its total stash to 9,334 BTC, worth around $561.6 million. Riot is on track to increase its self-mining hash rate capacity to 31.5 EH/s by 2024's end, aiming for 100 EH/s by 2027.
