no 6990? Weak.

[mellowhead]

Payment up front, or at the end of each month?

[nakowa]

no 6990? Weak.

sorry, that's a typo. the gpu is 6990. otherwise, 2 cards cannot generate speed more 1gH/s...

[nakowa]

Payment up front, I think you should know btc value will be rise up too soon sometimes...

[Scientician!]

no 6990? Weak.

The cards he's using should make no difference to you whatsoever (even though he IS using 6990s). 1 Ghash = 1Ghash whether or not it came from 1.5 6990s worth of flops or a hundred 1900XTs..

At current exchange rates, it looks like Vladimir might have some serious competition in the newly emergent mercenary miner market!

Nakowa is more than $100/mo. cheaper!

Cool service, but I don't see how I could make a profit with this unless I'm banking on bitcoin prices rising dramatically. If I'm counting on the raise in price, I feel like I would make the choice to invest directly in bitcoins.

$1900 could buy me about 95 bitcoins today. 1 Gh/s would give me about 1 bitcoin a day at the new difficulty taking effect in about 3 hours (about 868,000). So if the difficulty stays _completely_flat_ for the next three months, I'll only make 90 bitcoins. But we know that the difficulty is rising, so the most we could count on is about 50, and even that is pushing it.

I don't mean to disparage your services on your own thread, I'm sorry. But the numbers just don't add up for me. Does this make sense for anyone else? Unlike investing in mining equipment, you don't even get resell money. Am I missing anything? Can anyone give insight on why you would choose to do this?

Direct buying is clearly an option, but that doesn't necessarily mean no one wants to mine, albeit the difficulty is rising.

One other point:in many countries outside US, buying BTC is not as easy as you can imagine, at least not easier than direct mining.

Ah, thank you. That is a good point. The price is a lot higher in some other currencies too, when converted. I didn't take that into account.

I would say that the cost for this service (the three month plan at least), at this exact moment, seems to be about $45 a bitcoin. It depends heavily on future difficulty rises and only applies right now. I'm estimating at about 35% rises in difficulty, which might be low. If difficulties goes up slower, the price goes down. More difficulty? The price goes up.

Again, cool service.

It doesn't make sense to me either. I'm fairly sure he's pricing it just below the bitcoin costs.

He can't go too low because then it's just more profitable for him to mine the coins himself, and the risk just isn't worth the reward for the buyer in my humble opinion.

agreed. maybe a change in terms could make this more attractive, such as a guarantee to at least get your money back. if bitcoin goes down, op will at least have his equipment.

low risk low reward

Now _that_ is a good idea. The offer seems much more appealing now. Makes sense to me. Low risk, low gain, unless bitcoins go way up, then gain for everyone.
