Hi guys! I want to start mining bitcoinBTC and I found on ebay used Antminers S1 with 180-200 Gh/s for $80-100. I think it's a good price for that hash rate. What do you think about it 
?
?What are you trying to do?
Do you pay for electricy?
$80 is a little high for an S1 but not too bad, I see tons of them for $50 on kijiji in my area. I would HIGHLY suggest looking on kijijij, screw Ebay.
Situation A:
You are trying to make money and you are paying for electricty.
Answer A: BAD BAD idea you will lose money daily in power costs.
Situation B:
You are trying to make money and you do not pay for electricty.
Answer B: Not a bad idea you won't make much a day but without eletricty costs you will pay off your miner and make money.
Situation C:
You want to learn and get into mining
Answer C: Buying an S1 might be the best idea there is, very cheap per Ghash and hashes pretty quickly. You will lose money though.. Well unless the BTC price explodes.
