I sell all my S9 miners (13.5)
Miners are a year old but working on full hash, not damaged or broken and never overclocked.
0.035 BTC for each miner.
Reason I sell is I had for a year almost free electricity but now that stopped
it is not worth it for me anymore and already made enough profit. I have 19 miners for sale.
I only reply to emails: radirodr@gmail.com
