Wait, how do you get credit for your reservation fee?

you don't... the reservation fee doesn't apply to purchase price.

its just that, a reservation to be able to purchase at a certain price point

Well that's lame. OP should probably update the first post then, as the cost of the miner is not $500 and you cannot get two SP20's for $1000

Well, now that we published the link, you can "cheat" and buy direct, as long as the GB run.
It's unfair towards RoadStress.

Cant you just cross check orders made thru the GB link with a list from RoadStrees who reserved and paid the fee?

RoadStress deserves the fee small fee for setting this up, not to mention 60% will be donated.

We can, but we prefer to ask people nicely not to do it.
RoadStress definitely deserve the fees.

Sigh... I really want to, but I just can't. Even with the low prices it just doesn't make sense. Curse my expensive power. Tongue

But there is nothing available right now with a better power consumption. And nothing with a lower price. You just can't get anything better than this.

Well, the S5 does actually have better efficiency (if they hit their 0.51J/GH at the wall spec) unless you downclock the unit to ~1TH/s, at which point it's more expensive per GH/s than the S5. I won't get into that debate here though, as I actually do like the SP20 more.
I can only mine profitably at the current price of BTC until about 90B difficulty though, and I really have to massage the numbers to come up with a scenario where difficulty doesn't at least double before I pay off even a $500 (and $7 Wink

) purchase price.

I do want to get into it here.
Beside the obvious which is proven working design, you'll get the SP20 7-10 days before the S5. Do the math.

I also never said you'd get the S5 before the SP20, or that the S5 would be more profitable. Both those have too many factors to state absolutely. While I haven't actually attempted the math for a couple different difficulty curves, I would imagine running the SP20 full out now and downclocking it in response to difficulty would make it decently more profitable than the S5 almost all the time.

That doesn't change the fact that the spec of S5 is more efficient than the SP20, unless you underclock the SP20 to below the hashrate of the S5. I even gave you the caveat that they have to meet their spec for that to happen. Tongue

Fair enough.

Yes, and it is probably partially a miscommunication but I did ask if the deposit was refundable. A sentence that it isn't a deposit probably would have been appropriate, especially given the advertisement that the cost of two units is $1000.

It's very similar to RoadStress previous two GB.
Anyway, I don't know how he could have made it more clear:

So now that the product page has been posted, when is payment deadline? Because I didn't think this would be posted until the 28th. I'm not at home with access to my BTC wallet until after Christmas.

No problem. The sooner you'll pay, the sooner we'll ship.

Also, it's both disappointing, having sent my reservation fee, and unprofessional...

We do expect future participants to pay the reservation fee.
From past experience, once the link was up, there were some people that didn't.
RoadStress selected small, but meaningful reservation fee, a bit more than half percent, on purpose.

In a sense I agree but without RoadStress setting the GB up and most of us submitting a reservation fee then we wouldn't have access to this opportunity at all

yes it is

cost of the miner is $500 if you pay the reservation fee to be eligible to purchase at that price haha It would be nice to get a little extra off with the fee though
