Collection and calculation of miscellaneous expenses

Product Warranty Period:

Bitmain and other product manufacturers generally provide a 6-month warranty.

Return shipping fee:

Equal to the actual amounts incurred, we usually cooperate with either Deppon Express or SF Express for every shipment.

Electricity cost :

All machines would be hosted in our data centers in either Sichuan, which utilize only clean and renewable hydro-power (electricity price is around 0.05 USD per KWH in dry season, 0.039 USD per KWH in wet season) or the Chinese provinces Xinjiang or Inner Mongolia, which utilize thermal powers (average electricity price 0.043~0.057 USD per KWH throughout the year). These prices are for guidance only, and the actual electricity cost incurred may be different.
