The PreminePlus team is looking for a talented and knowledgeable altcoin developer to join its team, or provide assistance in windows-based QT wallet compilation.

Applicants must have a known track record for developing at least one altcoin, and have an excellent understanding of C++. Good experience with the QT library and IDE is also very much preferred. We're not looking for someone who just has the ability to compile QT wallets. They must also understand C++ to a competent level and be able to help in introducing additional planned wallet features.

There are two posts available, and while looking for a full time member to join our development team is preferable, we would also be willing to hire someone on a short term basis to pass on some necessary skills. All that would be required of this position would be the ability to help in windows QT wallet compilation of our altcoin. A good understanding of C++ is preferred, but not absolutely essential, provided the applicant has enough knowledge to compile windows QT wallets. This position is to pass on that knowledge, so again, payment would be dependent on the applicant's ability to successfully replicate their success with a highly competent member of our team. The applicant will also need experience with the GitHub repository.

The developer who wishes to join our team would receive a monthly stake of PMP along with the other developers. The stake amount would be decided upon based on experience and what they're able to bring to the table.

The developer who wishes to take on a short-term role of showing one of our developers how to compile QT wallets may receive a one-time stake of PMP, or a small one-time payment of 0.1 BTC, or a combination of the two. Payment will be made only if the applicant is successful in teaching our team member to compile the QT wallet. Our team member is a knowledgeable programmer so success is merely dependent on the skill of the applicant.

Interested applicants in either position can PM me directly. This is for serious offers only. If you need any further clarification, just drop me a PM.

I'm creating a service that will send out coins to users. The system that determines the payouts will be seperate to the one that sends them. (All due payouts will be stored in a mysql table and then retrieved by the secondary system for sending).

Aside from the obvious security concerns of ensuring my database can't be hacked/injected and so the payouts not be manipulated, or the service itself can't be exploited, are there any security considerations for the secondary system? As I'll be sending out a lot of coins, I feel having a cold wallet on a seperate machine would be ideal, however would the payouts be traceable to that machine in any way?

The wallet can be locked when not in use, however the secondary system will be online regularly, so I'm wondering what else I need to do to protect the coin storage.

Are they any good services around currently that offer the ability to create a scrypt altcoin for a fixed price? Or reputable devs?

I'm looking at developing a web-based game, and wish to use cryptocurrency as the in-game currency. I don't want it to be minable, however (although I suppose it would be minable through tx fees), and only obtainable through the game. At least initially.

What are some of the easiest ways of obtaining my own 100% premined currency? I'm not looking to "sell" this crypto, or even offer it on Bitcointalk. It's only going to be obtainable through the game itself as a payout.

The algo isn't a priority. Scrypt would be fine. Nothing fancy required. Just easy to launch, and easy to manage.

I'm guessing they ran off with the bitcoins? I haven't heard any developments on this theft for some time.

[market speculation]

I'm seeing more often lately threads saying "Coin x has a price target of $5, or $10, or whatever.

Don't be fooled. The only one who can determine the price is the market. Price targets don't mean anything. They may drive up the price for those who believe the price will get that high, but this is just an example of "fake it until you make it", and only serves to artificially drive up the price, because the only people supporting the higher price are the ones who believe in price targets. Those who don't are going to leave you holding the bag.

Unless the person giving you the price target is giving you solid reasons for their market speculation, treat it with a grain of salt.

I've done a fair bit of PHP scripting using the jsonRPCCLIENT library, but I've always ran my scripts locally. My intention is to run this for altcoins, not necessarily have a bitcoind command-line to work with, but will have to work with an open wallet.

What do I need to take into consideration? Is there a server mode for wallets? Any help would be appreciated. I'm pretty new to running wallets on servers.

I get there's a bit of drama right now, but do we really need so many seperate Monero threads? There's 8 threads on the first page of Alternate cryptocurrencies right now.

A bit much, no?

I can't be the only person here who is sick of the same old mantras and rhetoric.

Now's the time to buy.

Just hold. The price will go back up.

Very cheap right now.

That last one I really must emphasise. It is a fallacy. There is no such thing as "cheap" Whatever the price is, is fair, based on the current market conditions. Coins can be under-valued or over-valued, but saying a coin is cheap has no bearing on anything. We see the same kind of repetitious vacuous nonsense every day that tries to convince people to buy this altcoin or that altcoin, and very rarely do we get any sensible reasoning.

A lot of people are posting about Captcoin and Bitshares right now, for example. Neither of which I currently hold, I should point out. But every new thread I see tells me nothing about these coins, and in fact I would go as far to say that seeing a barrage of threads on particular coins devoid of any rational arguments is in fact turning genuine coin investors away, and merely appealing to newbies and those who are easily swayed.

I know it's all about who shouts the loudest, here, but it would be nice to see a bit more thoughtful technical analysis, don't you think? No wonder the scam coins thrive. The level of scrutiny is minimal at best.

I've got two rigs running, which work out at roughly 5 mhash/sec on Scrypt. That's two Corsair 1200 watt PSUs.

Since middlecoin went down, I've been looking at something else to keep the rigs profitable. Tried multipool. Doesn't even cover the electric costs. Just looked on Betarigs, and it doesn't even seem worth it either. 0.003 BTC per day on Scrypt, at best?

Anything else I should be looking at? I haven't had to touch the rigs for months as they've just been mining away at middlecoin, but now I need to make them profitable again.

Has anyone considered trying this?

So many coins out there which had potential that have fallen by the wayside, all in the name of the new "next big thing" to be released.

Collectively, I'm sure if enough members decided on one coin to revive, and focussed on it, it could be done. The coin would have to be old enough to essentially be dead and no longer listed on exchanges, with a fairly low difficulty and with as few coins as possible mined. Publicly available source in case a fork is ever needed. Little or zero premine, ideally, and enough members to work on promoting the coin.

A vote would be required to decide, with a large enough selection list to mitigate the chance of someone mining it in advance before a decision is made.

I think that would be the general criteria.

Starting to see the beginning of a horrible trend of 50% premined coins coming out. It's very disingenuous as you can bet there are going to be a lot of scam coins that will just get their premine dumped.

Soon everyone and their aunt are going to doing 50% Premined coins.

Basically, it's coin value x mined supply. If a coin has a declared premine, then the question is; should it be included in the market cap? a premine isn't the same as market supply, so I'm not sure why it's treated as such.

All well and good for legitimate coins, and provided coinmarketcap avoids the obvious scam coins, it will be fine, but it's just a matter of time before the community gets hit by one of these 50% dumps, and it's going to be devastating.

I'm not including AuroraCoin or MazaCoin in this. While questionable. they're certainly more credible than the garbage that's starting to follow in their wake.

How the hell will that work, then?

Coin Halving seems to be the age-old way of reducing supply over time, but I have seen a few slightly different approaches lately which decrease the amount slowly per block, or even based on a curve like with Stability Shares.

I've noticed that more often than not that when a coin halves, provided the level of interest remains the same, the difficulty also halves along with it. As this is the case, then what exactly has the halving achieved? If the reward has halved and so has the difficulty, then you'll still get coins at more or less the same rate.

Is the classic approach of Coin Halving just not suitable for fast moving altcoins? I quite like Foxcoin's block reward structure myself which slowly decreases the amount every block, or Mintcoin's weekly halving, which seemed to help with the coin's popularity.

I'd like to see more coins using curve-based block rewards, however rather than something to emulate how people expect coins are normally mined anyway, instead something to control the instamining that's rife with pump and dump scamcoins.

What would be wrong with low starting block reward, which gradually increases and then tapers off before then decreasing? Some coins do this in a crude way by making the first group of blocks low reward, which I think is quite a good approach, but it could certainly be better done with more advanced block reward adjustment.

So think Stability Shares, but instead of rewarding the earliest miners, start low and slowly ramp up the block rewards to give people time to adopt the currency. Then reward the early miners, and then taper off supply.

I have 2x Redeemable Origin voucher codes for Battlefield 4 for sale. Both came with my R9 280x cards.

I'm willing to accept most altcoins, provided I think they have any value. I do check exchange rates, so no lowball offers please.

PM or drop me an offer here for one or both vouchers.

I know the new rules state that giveaway threads are a big no no now, but I would like some clarification;

- Can giveaways/promotions be held in the main coin thread if the thread poster is OK with this?
- Would I be allowed to post a thread in the trading section enabling me to purchase signature space for coins?

Thank you very much.

Does anyone know any reputable sites that sell USB Antminers? preferably for BTC? I'm looking to buy a couple for mining SHA-256 altcoins, however would rather spent the BTC I've made from mining.

Also willing to buy from traders, provided they have a good rep.

Would:

Be sufficient for 4x: http://www.overclockers.co.uk/showproduct.php?prodid=GX-322-SP

So is 1200 Watts enough for 4x R9 280x cards? I hear these cards are power efficient.

Is there a web service that allows you to send multiple altcoin payments?

I'm sure I saw one mentioned a couple of weeks ago but can't find the link now.

I basically need a method of sending out automated altcoin payments at regular intervals. If there is a web service I can write a script to do it.

I was just authoring a DVD from a video file, and while it was running, I noticed my hashrate actually increased in CGminer by 40Khash.

Is it possible the software has some sort of hardware acceleration that can speed up Scrypt mining? I don't quite understand why it went up as the authoring software uses CPU, not GPU, but usually anything I use that is CPU intensive causes my hashrate to go down, but this actually caused it to go up.

Anyone else experienced this?

I can post the results if anyone would be interested. I'm not sure if it's a misreading in CGminer, but it seemed to be mining away as normal.

It's shifted it.

The amount of shill accounts I've seen asking for donations today in Alternate cryptocurrencies for one altcoin alone has been amazing.

Necessary evil, or something that needs to be addressed? I don't know. I guess you'll never make it completely fair no matter what do you, but it is a little annoying seeing one person carrying 20 begging bowls instead of 1.

Is it something we could potentially report if we suspected someone of extreme shillery?
