meanwhile good news a nice guide how to mine groestl algo with linux

and his impression:


update:

my own impression mining with two rigs 3x amd 290 and 6x amd280

with scrypt i did use 3000w all together
with groestl im at 1500w all together and silent

using windows 8.1 one one and windows 7 on other rig

how many blocks are left until we are pure pos , when we are at that point a multipool would be nice, especially because there is such a low amount of coins on cryptsy , once those are gone we could essentially dictate the price

I had to move my mining rig to the house extension as I couldn't stand the noise. For me profitability of mining has been consecutively falling, due to ever growing difficulty, dramatic fall in value of coins I used to mine, so I ended up with the situation that I was mining just for the sake of it. Electricity bills were getting bigger as well with price increases every now and then.

With this new algo, all the problems that led me to abandoning mining are becoming a thing of the past. At least for the time being difficulty will be at the alright level and not so ridiculous as with i.e Litecoin or Doge, value of the coin will be increasing so even if difficulty eventually rises it will compensate, the noise level will be way way down (which is a big factor for me). Diamond Coin with the newest implementations is a solution to many people's problems and if you add Proof-of-Stake into the mix it's really unique and becomes the most eco friendly, most energy efficient solution on the market that satisfies needs of most groups of people from miners, minters, long term holders, traders(for being fast and stable), etc.

In cooperation with Groestlcoin devs we'll promote all kinds of mining solutions and thanks to this algorithm properties people will be able mine with virtually any modern mobile device. Diamond Coin is a win-win coin and in my honest opinion should be named as such.

we are clear a 1st generartion coin because we are based on bitcoin code
which is by definition not bad the most valuable coins are 1st generation

BUT in my opinion we are a far advanced EVOLUTION of 1st generation coins

thats why we called this release:
[ANN] Diamond Coin (DMD) Evolution v 2.0

By the way, it would not have been bad idea for DMD to run with different PoW algorithms in parallel, each with it's own difficulty and pace. That way, if some algorithm suffers from ASICs etc, only that algorithm's share will be 'unfair'. Of course, PoS is an entirely different beast.

I looked into this more and it depends on which pool you mine from.  If you get too many accepts going on, you need to raise it.  If you don't see any accepts, you need to lower it.  I would guess you should see about 1 accept every 30 seconds would be good.  You don't want the pool to get overloaded with accepting shares and you want to submit your work at least once per block.

Well, at that rate why not set it up to automatically trigger a switch, when appropriate, to one randomly selected among a predefined set of algorithms?

At this point I would say you've got a lot of interest, not demand. That's not to say demand won't develop.

I started mining GroestlCoin in preparation they have some very good mining info. http://www.groestlcoin.org/pools and a spreadsheet with settings that people have submitted.
