Butterfly labs has been a long running and very established company that had been running a business selling a huge variety of Bitcoin mining hardware with a price range of $150 to $30k and over. However recent events have suggested that Butterfly labs has been a fraudulent company ripping off thousands of customers of over $30 million.
