Viperatech is legit but takes patience. US company location. Can pay with cryptocurrency. Like all ASICs you generally have to prepay for a nonexistent product that doesn’t get drop-shipped from China for 2 to 3 months which does suck. That being said Viperatech is trustworthy and so is Jasminer which is a huge plus!

Ordered miner Ordered miner, told me its in stock and that they can send it as soon as they recieve the payment. They received it and 10 days later still did not sent the miner, say its a delay and offering refund. I need the miner and not a refund, if they were fair they should send a partial refund because of waiting that was not the deal.

Bitmain 9.4TH Hello, thank you very much for 9.4TH, it finally arrived. Communication by email and normal telephone was rather difficult, but I experienced very fast and good communication on WhatsApp. We received a tracking number via email, which to this day has the same status as "Shipment information received HONG KONG - HONG KONG SAR, CHINA", but we received the normal one on WhatsApp. For a week and a half, we were afraid that nothing would happen to our package, but then it arrived very quickly. Thanks Viperatech!
