How much do you think you'll be able to sell an Antminer S1 on ebay for in May/June ?
I'm starting to think I'm crazy for spending 2.9 bitcoins on two Antminers only to barely be able to make 2.9 bitcoins
Unless you live in part the world where its autumn in May or June they won't be worth much where atmospheric heat makes them less valuable as spot heaters that also provide some lunch money.
