No.

300MH/s = .67BTC/day
= $5.70/day
= $171/month

And anyone with that kind of MH/s is probably using no more than 250w of electricity, so 180kwh/month, or about $18 more in electricity per month. Well, if you get decent rates on electricity, anyway. $72/month at most though.

Mining is far from being unprofitable. When difficulty hits 4M, then we'll talk about it being unprofitable for a good portion of hobbyist miners.

My margins are much lower but yes i see there is still some profit my power rate is almost double what you quoted for yours and my mhash is more in the range of 240mhash.

Thanks for breaking it down, i feel like it will force some people out but we will see.

You're certainly right that some people will choose to shut down because of it (as evidenced by this thread), but I think just the worst efficiency cards are being forced out at this point. NVIDIA cards, certainly CPU mining, and a few of the really low-end ATI cards.

The worst ATI card for Mhash/watt is the 4550, which gets 7.23mhash for 25w.
7.23MH/s = 0.016147 BTC/day
= $0.14/day
= $4.21/month

These numbers are making me lol.

Anyway, electricity usage would be 18kwh, which would be roughly $1.80 at $0.10/kwh. At $0.40/kwh though, you're looking at $7.20/month, so you're definitely losing money.

So if you live in California and are mining on a 4550, STOP. Tongue
