3  Alternate cryptocurrencies / Altcoin Discussion / [XPM] Why Primecoin is Useless, Doomed to Fail? on: August 14, 2013, 06:23:01 AM
[XPM] Investment Analysis: Why Primecoin is Useless, Doomed to Fail?

1) Primecoin is not a Commodity

Unlike Bitcoin, there is no cap to how many Primecoins will be made. What determines XPM production rate is the demand. XPM is not scarce – this is what drives BTC prices up constantly.

Due to difficulty algorithm of Prime, here is what happens:

Demand Increase -> Supply Decrease

Demand Decrease -> Supply Increase

 (higher demand -> higher difficulty -> less reward per block, but the rate of block generation per day is dynamically adjusted by the client to be stable at approximately 1400 blocks per day. => that means higher demands leads to less Primecoins production rate per day).

Primecoin:
- 1 block per minute.....How often is difficulty retargetting?
- Reward is 999 divided by the square of the difficulty....So,

diff    reward
8   15.609375
9   12.33333333
10   9.99

==========
That means when demand plummets, Primecoin price can bottom out to zero, but when demand rises fast, its price can sky rocket above BTC's level very easily.

This characteristic, while appealing to day traders, because of huge price swings as we have observed, is a bad element for long term investors - unlike bitcoin, there is no guarantee or a logical prediction that each XPM you hold will gain value in the future .

Put it this way: when demand decreases, the difficulty will drop, that means there will be more Primecoins mined everyday, but since no one wants them anymore, it will be unprofitable for miner to keep mining, so they give up, leading to more difficulty drop, which means even more Primecoins will be generated, and so on... until everyone have a huge stash of Prime worth exactly nothing (by which time your investment has evaporated). This is why it's a very bad idea to invest in Primecoin.

2) Primecoin is not a Currency

Prime is less secure than bitcoin, more prone to 51% attack (attack can happen with even less than 50% priming power) as stated in white paper.

Prime still takes minutes to confirm, not 3-4 seconds like Visa => no average Joe will ever use it, even if Sunny has plans to promote it, speaking of which...

There is no plan for any further development. This start to look like PPC - pump and dump scheme, just waiting for the next Primecoin alt to be released with a few parameters changed, like different difficulty algo, for example.

Besides that, Primecoin is pretty much a Bitcoin clone with different hashing algorithm.

3) Conclusion

If you release a new PrimeClone that is exactly the same as Primecoin but with limited, lets say, 20M coins cap, it will quickly get more interest than Primecoin, because your PrimeClone will be scarce and will attract long term investors.

Demand is simply perception,

Perception is based on believes,

When people stop believing all the crap talk about Primecoin, such as usefulness for scientific research (because some smart mathematicians have spoken out in this forum confirming no validity of such arguments, but pure speculations) the demand will fall. Shortly followed by price drop and VPS mining farms down.

By the time only botnet scammers remain operating, Primecoin is over, paving way for PrimeClone or something else, or perhaps Sunny can make a new coin based on new innovative hashing algorithm!

Even his supporters got pissed when he announced Primecoin last month!
This is hilarious, check it out.

========
Rumor/Truth? (you decide!)

Primecoin does have purpose other than solving for primes. It's meant as an attack for mining market share. The plan is that this will help gain acceptance of PPCoin in the long term. Whether this actually happens we'll have to wait and see.

4  Alternate cryptocurrencies / Altcoin Discussion / [WTS] GPU MINER RIG 2.2MH/s 750W - Sapphire 3x7970s - $2,195 NZD on: August 05, 2013, 11:28:47 AM
Only selling to Aucklanders (or within New Zealand).

Up for sale is 4 x fabulous mining rigs I built myself with love and passion!


You can buy just one or all 4 of them.

The miners are only 2 months old, built from brand new parts bought from PBTech with original packaging and copy of receipts for warranty purpose (warranty will be fully transferable to you).
Exception- two or three hdds where bought as second hand.

REASON FOR SELLING:
Currently in my apartment there is no balcony or secure backyeard that I can just leave these rigs, so it's getting a little hot here to run 24 x 7970s inside our my living room, (getting complaints from room mates) so selling half of it.



SPECS (each mining rig):
Cost: $2,195 NZD (inc. GST)
Hashing: 2.15MH/s (I underclocked it minimize Power consumption, can easily do 2.25MH/s)
Power ratings: 750W (measured at the wall)
Setup: automatic mining with CGwatcher (just change you mining pool info)
Automatic mining restart in case of power failure - simply switch power on and it mines!
Been running for two months straight perfectly smooth with zero failure, no manual monitoring is required.
OS: Windows 8 (unactivated, but as a miner you don't really need an activated Windows machine)
Remote Monitoring: VNC installed for easy monitoring through another computer.



PARTS:
CPU: Intel Pentium G2020 2 Core
RAM: STONGTIUM HYNIX 2GB DDR3 (one of them has KINGSTON 4GB)
MOBO: Asus P8B75-M LX
HDD: second hand, varies: Seagate, Western Digital, about 40-80GB (one rig has brand new HDD 300GB)
PSU: InWin Glacier 900W Modular 80 Plus Gold 7 Years Warranty
GPU: 3 x Sapphire Dual-x 7970 3G OC
(two rigs have 1 x Sapphire Vapor-X 7970 and 2 x Dual-x OC 7970 - will cost extra $50 each for these two rigs, or I can swap them with Dual-x to keep prices the same).
FANS: 2 x Cooler Master SickleFlowX

Full article describing how I built this rig.

Due to nature of mining rigs, all sales are final and there will be no refund or returns from me. If anything goes wrong after the sale you can just go to PBtech and get it returned or fixed (you'll have copies of all original receipts and signature from me stating warranty transfer to you directly, so you can get full benefits of warranty from the retailer that sold parts to me.)

The price is pretty much non-negotiable, as I already set it as low as I possibly can. Can arrange some shipping if you are outside of Auckland (cost TBC).
5  Alternate cryptocurrencies / Altcoin Discussion / [XPM] Why Primecoin Price Has Bottomed Out on: July 31, 2013, 10:41:06 PM
Original article here:
http://ecoinomist.com/xpm-primecoin-price-bottomed

Ever since Primecoin has been on exchange, we have seen quite a radical price swing from as low as 0.0019 to as high as 0.019 (x10 times fluctuation) just within the space of one week.

This is by the far the most profitable altcoin to date for speculators to trade with the typical price swing of 10-20% per day if sold/bought in the right time, with huge initial volume of trading that no other crypto has matched for such an early release stage.

So why has the price hit the floor recently?

Some possible explanations:

A)
While it's not profitable to mine with VPS, such as DigitalOcean or Amazon EC2 any more, the early miners like myself, who mined XPM in the first few weeks were able to mine at a profit even at the current exchange rate of 0.0061, mainly because the difficulty back then was way lower than now. But just like many miners, I saw a very rapid price increase x10 times just within the space of one week, thus suspected XPM might be on big exchanges like BTC-e soon. So I held on and did not sell much.

Now many VPS miners end up with a stash of XPM that they have paid hard cold real world cash for, which for some, due to economical reasons, they might have to sell some in order to recoup back the initial investment.

These are the kind of reluctant sellers, who would only sell just enough to cover his/her overhead -> thus we observe low volume of Primecoin trading lately.
The major Primecoin exchange mcxNow has hit the lowest XPM trading volume ever at ~170 BTC per day.

B)
The only people remain mining XPM right now are the botnets (zero overhead) and VPN operators who have access to server computers at much cheaper prices.
For botnets, obviously the is no need for price consideration when it comes to selling - they make profit at any rate.
This might well be what the current reality is, if we look at the infrequent trading volume that tends to spike out of nowhere:

Whereas in the peak period the trading volume was spread quite evenly between all hours of the day.

In Conclusion

The current Primecoin market is dominated by a few big XPM holders and speculative buyers.
But we shall see some changes very soon, when a working GPU miner comes out, which will certainly even out the playing field for everyone.

Dus tot he difficulty machenics of Primecoins, higher mining power means higher difficulty, which results in fewer XPM rewards per block. And because Primecoin has dynamic difficulty adjustment that changes on a per block basis, it means Primecoin will become a lot more scarce then it is now.

The question is...

How well will Primecoin be received by the GPU community?
Based on this thread, the interest seems to be astronomical.

Also, considering that fact that Litecoin has become increasingly hard to mine, and all the other altcoins really have no true innovation or future, besides pure hype and speculation, Primecoin is the only one at the moment to fill that gap for large and small GPU rig owners.
6  Alternate cryptocurrencies / Altcoin Discussion / [XPM] Primecoin Huge Drop in PPS on: July 21, 2013, 05:59:49 PM
Anyone noticed a huge drop by 40% in PPS mining?

I just noticed this thing taking place at exactly 16:24 UTC July 21.

First I thought it was the VPS provider that did something to my account, but upon inspection with other services (I use three different VPS instance providers) and including my local rig, the drop was indeed confirmed to be client related.

I use mikaelh's HP5 client, but this drop has been confirmed on HP4 as well.


As you can see, PPS dropped from 14k to 8k pps.

CAUSE?
I predict it has something to do with new difficulty increase to 9.0?

Anyone got any other findings?
7  Alternate cryptocurrencies / Altcoin Discussion / [XPM] Primecoin GPU Miner on: July 16, 2013, 01:56:52 PM
I know some of you here have already begun mining Primecoin with GPUs and may still be holding on to them to collect your stash before announcing the miner script.

What I'm proposing, is if you are among those few who managed to alter CGminer or similar scripts to mine on GPU but you don't have good hardware, I'd be keen to rent out 1/3 of my rig for free in exchange for you to share the script with me. I will not be sharing this code with anyone else, for obvious reasons - this will be between us two, you and me until you are happy to release it to the world wild west.

The opportunity to stash XPM with GPU won't last long, as I'm sure you are not the only one who found a way to GPU mine by now (though I don't personally know how). That's why you might as well maximize your chance by partnering with someone who has good hardware like me.

My rig is 24 x 7970- that means you will get 8 x 7970 worth of mining for free for at least one week or until you get 10K XPM (amount is negotiable), which ever yields more XPM for you, providing your code is efficient enough for me to keep mining it by then, and not switching back to LTC. Here is the picture of my rig as proof that I actually own it (click here to see the article):
