Well, i havent been on this thread in a long time. The company i made a $6,000 purchase from is in the process of finally declaring bankruptcy - according to his letter to the federal court I am suing him in. The company i dealt with was called AMT miners and the owner is a real scumbag called Joshua Zipkin. This man, I believe, is or has been trying to start other companies. This is just a friendly note to those of you out there with large amounts of cash and a willingness to purchase a bitcoin miner... "stay away from any business with Joshua Zipkin" i wont bore everyone with the details but suffice to say the man is a pathological liar and a terrible businessman. Last told he fled to Bulgaria to essentially escape prosecution here in the United States. Be warned. I paid him $6,000 cash and he never sent me a thing. he even bragged about not sending me anything. please folks do not make the same mistake I did. he will not change. he intentionally defrauded a LOT of people. I was just one of his victims. there are many more. happy mining folks - i dont think i will ever try to get back into biotcoin mining. too much deceit.
