Bitcoin Forum

As some of you may know, recently there has been several break-thru in GPU mining for several CPU coins, such as Protoshares, Quark etc...

This got me interested in developing a GPU miner for Primecoin, and after spending much time on it, I have done it, I have developed a GPU miner for Primecoin. The performance is about 8-10 times of a similarly priced CPU. My single AMD R9 270 gets 4.5 chains/day, compared to a i7 4770k only 0.6 chains/day

I don't own a GPU mining farm, therefore I'd like to recoup my development time cost by distributing this GPU miner to any interested person, with a cost.

The cost is 1 BTC

The miner binary will be distributed to buyers, but no source will be provided. Also the miner will be IP restricted, so you can't easily distribute to others.

Purchase procedure:
1. send 1 BTC to 1Mh5oXgXwRnd4AMr2wXimKtN4Fp8utiwnh  (you should include your forum id with your transaction if you could)
2. PM me your transaction, please do so immediately after you sent the transaction, so no other person can claim your transaction.
3. with the PM, please give me the external IP address your miners will be mining from, and I will compile a version with this IP address just for you.
4. if you need to change the IP address later, PM me again.

I will open source this GPU miner after 3 months, so you have 3 months to mine exclusively using GPU (along with any other buyer).

While some may think it is not expensive , most of us wouldn't spend 1 btc on this . I think that in the long term you would benefit more if you implement some kind of mining fee (reasonable % of coins going to you) into software and give it for free.

With a single rig of four R9 270, you can get 40 XPM per day, you will make your investment back in a week.

If you what you're selling is actually true....

buy some account with more posts, or use your real account, then maybe some ppl would believe you

first copy has been sold, transaction has confirmed at my address, the buyer wish to remain anonymous.

Why wouldn't you urge the "buyer" to vet/confirm on here for your sake?

I did, but the buyer do not wish to reveal his identity here.

shocker

I volunteer my services to verify. I have like... the worst hardware so I can definitely test it and will post my review for free! ;)

I will test with an i7 compared to a gtx560. I will even go the extra mile and post a picture of my hash rates! WHOAAAAA

Who is this guy out of left field offering his services like a gentleman?! I am exactly that sir. A gentleman offering his assistance to a fellow forum member in need of some guidance. Contact me posthaste!

So why do you sell it? Buy 2 R9 270 for 1btc and start. You will make your investmet back in a week.

@btcinvest

Are you sure you even know how to mine Primecoins? Your numbers do not even make sense.  ;D

Agree! He somehow doesn't know how to calculate with the profits. 4.5 chains/day with R9 270. 4xR9 270 get you 18 chains/day which could yield for you at least 120XPM/day = 0.5 BTC (roughly).
So 1BTC is too cheap for this. Why don't you charge 10BTC or 20BTC?

Did he put his phone number in the transaction?

Windows binary or Linux binary?

Additionally, if you are willing to use escrow...

Can you post few screenshots?

Still too good to be true. Will wait for a proper review from a trusted source.

I think this is scam... 4.5 CPD for today very much power, top CPU have only 0.2-0.3 CPD..... SCAM!

Lets Use Escrow, You have the power to control IP so if i will not pay you you could control my IP or close my service but if i will pay you in advance what will be guarantee that you are telling truth? Can you come in this point? I will get it so i will use atleast 6 Hrs then i will relese fund.
I believe every member will love this Idea.

I'm up for a test and/or escrow. I got a whole bunch v GPUs so I can test and give proper results

looks like scam you must provide with a video

If it was no scam, he would provide it anyway. And I am pretty sure the received 1 BTC was his own. And if it was really true, here in this thread would be 40 pages within a day...

probably SCAM

Would love to see proof, video of system mining and the beeeeer.org user page.  According to your stats..... you should see it raise with every page refresh.  TBH, I really doubt this is legit.  Specifics on the implementation would be cool too. 

its been shown GPU XPM mining is not currently feasible, what do you have that others do not?

if this was really happening he wouldnt be on here sharing his money making software with others, hed be rolling in it himself. either that or it would be selling for a bare minimum of 20btc. just my 2 cents worth. make your own decisions.

How about you give me a copy and I'll *promise* to send you 1BTC when I convert it from the XPM earned using your miner.

This is 100% SCAM
I gave him a good offer but dont want to reply my post even others
That was my Offer for OP

If you were actually a competent developer you'd know how retarded it its to use public IPs as the limiting factor. Scam.

you guys are wasting your time on this thread. obvious scam

No reputable confirmation miner exists. No screenshots, no evidence. First buyer wishes to remain "anonymous".

Advise extreme caution. Looks like a scam until proven otherwise.
