Bitmain.com has lots of negative reviews on https://www.trustpilot.com/review/bitmain.com and with more people wishing to enter the mining industry Bitmain profits grew to over $3billion in 2017. Bitmain is one of the biggest manufacturers of the Bitcoin mining machines and many individuals reported they they god scammed by this company with the puerchased miners never being delivered even if the clients made the payment on time as requested by Bitmain.
The evolution of Bitcoin as a perfect solution for the financial system of the future has driven a sudden interest in a lot of people and urged them to enter the mining industry but unfortunally Bitmain prooved to be a Scam who tricks its customers. Bitmain.com practice a dishonest no refunds policy and it's dishonest because a legit no refunds policy can't be aplied to products that were in fact never delivered. Any serious company would give refunds if the purchased merchandise is not delivered, maybe not for shipping costs but the product's price must be refunded. You can't take the money and not deliver the product, this would be a Scam.
There are other risks involved when purchasing from Bitmain.com
Order Shipment - The fact that your order doesn’t ship for 2+ months. With the changes in difficulty, the “as advertised” earnings at the time of purchase are not the earnings to be expected once the rig makes it to your house.
Payment method - Payments must be made in crytpo and sometimes Bitmain accepts wire transfer but lately Bitmain.com decided to accept only Bitcoin Cash. We all want crypto to be the new form of payment, however, sending crytpo overseas to a company whose country is restricting the use of cryptos is cause for concern. Pay now and wait 2+ months to get it… This makes it difficult to start a legal procedure for example the Chinese government doesn’t recognize foreign courts so the scammed client must have a Chinese representative (you can read more on http://bitcoinmoneynews.com/how-to-sue-chinese-company about how to sue a Chinese company).
Faulty products - Many people accuse Bitmain that the Antminers they have purchased are faulty. Bitmain says it has a "No refunds" policy so the clients have no chance to get working mining hardware. Many clients scammed by Bitmain reported that the broken miners they received were actually used by Bitmain to mine Bitcoin for Bitmain's profits before shipping that same miner to scammed clients.
Warranty - Many people accuse Bitmain that the Antminers they have purchased are faulty. Bitmain says it has a "No refunds" policy so the clients have no chance to get working mining hardware. Some sent the faulty products back for Bitmain to repair it but never got a working miner back. Clients also need to invest a lot of money because the mining hardware is very expensive and also the maintenance cost is too high. So definitely, there is a very high risk to lose your money.
Customs - I’m sure getting this unit through US customs is not a problem for some poeple but the potential for it being rejected and sent back is concerning. If you will want to contact Bitmain about these matters or problems they will reply you with the same message again and again. They really have extremely poor support.
