ABSOLUTE SCAM!
ABSOLUTE SCAM!! They only accept cash or Bitcoin and then rip you off.. Purchased A3 and X3 miners. When marketed theses miners had massive profit. By the time Bitmain finished mining with my miners and flooding the market with miners in one hit the difficulty went through the roof making these struggle to cover costs. It is an absolute scam. The create an ASIC for an AltCoin then market the huge profit potential based on the current difficulty. While you are waiting months for your miners, they are mining the hell out of the market with your miners. When the difficulty rate goes through the roof then they deliver you the miners worthless
