Are HashFast chips/boards/system worth anything any more?
Assuming 0.80 Watts/GH, at 550 GH you consume 440 Watts and generate a decreasing return of 0.006 BTC per day ($1.46)
Even in the chip, board, power supply, fan and cooler were free, is there any place in the world where the power needed to run these chips/boards (10.56 KWh/day) costs significantly less than $1.46 per day?
That's 13.8c/kWh. There are plenty of places with power less than that.
Price of electricity of even half of that is available in many, many places which can provide server-friendly environment, but the problem is that transportation of the miners across half the world and eventual one-time customs' fees + VAT (up to 30% here where I live) my bring it to zero profitability again.
