Not entirely sure, but I would still power them even if you don't think you need to.

It's still worth it imo.
It's gonna be some time still before asics hit the market, and even when they do, they'll only be about twice as good hash per $ and not 10+ times like with sha-256.

Short answer: No it's not worth it.

At 3K TH mining bitcoins, you'll make it back in like 25-30 days, and that's if you had it right NOW.
You probably won't be getting yourself a Neptune until at least May... by that time the difficulty would probably have risen 16+ times.
So you probably won't ever make back what you put in - maybe if you mined some and resold you could make some profit... barely.

I think it's pushing it, I wouldn't. Especially since the 290 draws a lot of power.

Yeah, maybe you plugged the 1x riser into the motherboard backwards?

It's weird that it would be the PSU imo.

Are you using powered risers?

Thanks, I'll be sure to check it out.

Edit: Fuuuu- not available in California. For peet's sake, California has nearly 40 million people. Oh well.

This is incorrect. The CEO of PayPal David Marcus has already denied these claims:

    To clarify: we have no policies against using PayPal to sell Bitcoin mining rigs.
    We don't support any currency txn whether fiat or BTC for a host of regulatory
    issues. But we treat BTC and any FX txn the same way. We're believers in
    BTC though.

There was a communication error in January but it was retracted within hours: http://i.imgur.com/GMC0fsd.png

So at the very least mining rigs are okay to sell.

Mt.Gox has had shitty cash withdraws for many, many months. Hence why the price is always higher on that exchange than any other.

Right now I'm using Coinbase. Ever since they changed the instant deposit limit from 10BTC to 1BTC, it's been a drag buying BTC in a timely manner.

Are there any sites that let you transfer from a bank and you can get funds/BTC instantly?
I know local BTC is one option but I'm not sure how convenient that would be - seems like there's quite a bit of markup as well.

Markets with higher prices almost always have a reason for it.
Low trade volume, large delays in cashing out (weeks to even over a month), caps on how much you can cash out per day/month, etc.
Some exchanges also impose fees on cashing out (1-2%).

With such large delays in between reinvestments, there's also a chance that bitcoins could go up or down 20%+.
Meaning a lot of missed chances at potential huge profits that you would've had otherwise.

As quoted, arbitrage is like picking up nickels in front of steamrollers. You can make some small profits, but there's a chance you'll be crushed.

Ehhh, starts in May. Don't think that's worth it.

Jesus, that's one expensive lesson. Really sucks man.

End of Feb shipment is awfully close to when TH miners become available.

No, and I don't advise that anyone should.

Any idea on price and when units will start shipping?

In chargeback cases, usually if you have a tracking # that you've shipped a physical product to the buyer it's enough to fight the case.

That's perfect, I think I'll go that route.

Thanks guys, closing this.
