![]() If you intend on getting one of these devices, adding a heatsync with some thermal paste will increase its lifespan drastically. 4 watts (a 20% decrease) most likely due to the temperature drop in the voltage regulator, increasing its efficiency and wasting less power in heat. Power cost per month: 19 cents (about 1 KW hour)Īfter adding a heatsync to the USB Block Erupter, it used less power by.BTC per day: not given (varies based on pool).Join the Scarce City Banter Telegram channel for auction updates, commentary, and sat giveaways.

Market value for 1.99 BTC was around $200-$225 USD at the time.
