Cryptocurrency seems to be infecting everything now and this new heater from a French startup seems to be a natural evolution of this infection. The heater is manufactured using two Sapphire Nitro+ RX 580 GPU's (has normal heating conductors as well) and mines Ethereum by default. Put your wallet address into the mobile app and off you go to mining and heating your home. You can buy this device for the low, low, low, price of just $3,600. Did I say low price? My bad. The company thinks they'll sell hundreds of these in the next year. I'm not so sure about that. However, the saying a fool and his money are soon parted comes to mind. You can set it up in a few minutes by plugging an Ethernet cable and putting your Ethereum wallet address in the mobile app. You’ll then gradually receive ethers on this address - Qarnot doesn’t receive any coin, you keep 100 percent of your cryptocurrencies.
