1,500 MHash/s for 8.35 BTC - This works out to 0.795 BTC per day per 1 GHash/s
3,000 MHash/s for 16 BTC - This works out to 0.762 BTC per day per 1 GHash/s
But with 1ghas u can generate ~0.65 btc/day, why someone is going to pay 0.762 ?? I dont get it.
Ease of use, avoid electricity cost, etc.
The math is not as simple as: $ cost of GPU/MH/s = cost per hash!
Ok with that.
But if i want 10 BTC, i will need 1 GHas/day for 15,4 days, so i had to pay u 15 x 0.762 = 11,72 BTC (about 58,26 USD). But i can buy it directly in MTgox for about 50 (and about %5 less if i buy with cash to a local BTC seller...) and without waiting more than 15 days...
Still dont get it...
