156
I just don't understand, you'll never get your money back at a price like that... There is a reason why BFL sold them for $1225 (later raised to 2500). Today it will make 35 BTC per month, in 10 days it will make 30, 11 days later it will make 23, 11 days later it will make 18, after that other companies will release large ASIC units and this machine will produce maybe 4 per month then 2...
How could someone spend 156 BTC on it? The current value should be 30 BTC.
Man.. You don't have to buy these items for this high amount of
BTC . Maybe he sells it ulterior for more money. You don't know. Or he wants it as a collector item..
Deal with it. It happened.
