Bitcoin mining machines took a major leap in 2025, with top ASIC rigs crossing the 1 PH/s mark and energy efficiency improving sharply through hydro cooling and advanced system design.
Bitcoin mining hardware took a major leap in 2025, with petahash-class machines, hydro cooling, and tighter J/TH ratios reshaping competition among industrial ASIC makers.
A long-dormant holder redeemed two rare 100 BTC Casascius bars in April, moving 200 BTC for the first time since late 2012. The event highlights the shrinking supply of unopened physical bitcoin collectibles and the billions still locked inside sealed Casascius pieces.
Bitcoin.com's Jamie Redman tested the Ledger Nano S with his 7-year-old son. The $65 device supports Bitcoin and Ethereum, features a 4-digit PIN and 24-word seed, and boasts an intuitive Chrome extension interface. It rivals Trezor in ease of use at half the price.
Bitcoin's 14.6% rally over 30 days pushes hashprice to $60.49/PH/s. The leading ASIC miner, Antminer S21e XP Hydro 3U, nets $35.66/day. Even micro miners earn pocket change, while aging S9s revive under cheap power.
Bitcoin's 30-day rally (+14.6%) has lifted hashprice to $60.49/PH/s, boosting miner profits. Bitmain's S21e XP Hydro leads with $35.66 daily profit, while legacy S9 series are underwater at $0.06/kWh but can still turn a profit at $0.02/kWh.
With Bitcoin surging 14.6% in 30 days, the hashprice for 1 PH/s climbed to $60.49. The Bitmain Antminer S21e XP Hydro leads with $35.66 daily profit, while micro-miners like the NerdQaxe++ earn ~$0.18. Vintage S9s lose money at standard power costs but turn profitable at $0.02/kWh.
Bitcoin’s recent climb has improved ASIC miner economics, with leading rigs generating more than $35 in daily profit at $0.06/kWh. New-generation machines are benefiting most, while older S9 models remain unprofitable unless power costs fall sharply.
