Hi,
i don't know which pool are you using and how much are your earnings, but i feel that either the pool scammed me or it's not worth the struggle to mine this coin.

Pool: xmg.suprnova.cc
My hash rate: 30-35 KH/s
Earnings: 0.01941802 XMG in 2 hours
Current XMG/BTC value on Bittrex: 0.00004747 BTC
BTC value: 2300 USD roughly

So i've got 0.00212 USD in 2 hours which is like 0.0254 USD/day

Just 2-3 cents a day??  Angry
I would probably consume 10x more money in electricity for each processor.
Am i missing something here? Probably i got scammed

Which pool are you using and what earnings and hashrate did you got?

HAshrate:


Mining client: wolf-m7m-cpuminer-V2-x64-0204 on Windows 10 x64


Processor: i5-6200U @2.30 Ghz , i was using all the 4 threads


I have been using Zpool for awhile and it's one of their top coins to mine now.:
Pool Stats (m7m)


 2% fee. Still end up for some good numbers at the end of the day. Granted, I'm one of those "IT Guys" that have a lot of miners, but still profitable for 2-3 miners.

I mine it with all of my rigs, with G3930 Celerons.
No hash decrease on EWBFs miner, runs almost for a month like that without a problem.
I don't know if it's the miner, or the OS, but the OS, or any other app have always higher priority than the miner. So your XMG hash will decrease if the OS needs some CPU power, and then when it's done, it will give all the CPU to the miner again.

You can really mine some XMG on your regular desktop too, not just on a mining rig.

Just keep on mining, and hope the price will raise. Smiley
Yes thats it. Btw with lots currencies it is: You have  money? You can make more money! For mining Magi you dont need money to mine some. Just a simple cpu can do it.

That sounds about right.

It's really not profitable at all right now, so if you like the coin, it's much better to just get it off the market for much cheaper Smiley I think the competition consists mainly of IT workers that have massive server farms where they can run this on for nothing, but a personal guy wouldn't really be able to compete against this, unless you're happy with hurting your CPU 24/7 for next to nothing Wink



When talking about CPU mining some people here say that it is done mainly by botnets , so 0 elecrticity cost.
But i wonder how the infected PC users do not even notice that their CPU and fan are working at full speed ... hence i don't believe that botnets are used for this task

30% speed boost.  Still part of that same original offer, but if I get it fast enough to be profitable on AWS before anyone takes me up on it, the offer disappears. Smiley

I should stop.  But it's too much fun. Smiley

45% speed boost

[2015-07-04 16:07:11] accepted: 59/59 (100.00%), 141.65 khash/s (yay!!!)

Finally hit 50% speed boost.  Cool beans, though it's now AVX2 (haswell and later)-specific.  Any takers yet? ;-)

This is at 45W package on the i7-4770 (up from 43, but a large gain in perf/watt).  Still not thermally throttled - CPU is at 82 degC.

Wonder if it's more profitable than Monero at this point.  Hmmm...

82°C for the CPU is really high ! Even when I had a CPU fan I never went so high !

Also, can I just say:  What the hell is with that weird Gauss-Legendre numerical integration that doesn't involve any variables from the block?

I personally think it looks much nicer this way - not that it reduces the runtime much, but getting rid of unnecessary complexity in a hash function always brings a bit of sunshine to my day:

Code:
double GaussianQuad_N2(const double x1, const double x2)
(blah blah blah)

---->
uint32_t sw2_(int nnounce)
{
    double xm = (sqrt((double)(nnounce)))/900 + 50;
    double x[4], w[4];
    double z;

    double s =  0x1.23456789abcdfp-1 * xm * swit2_(xm);

    z = 0x1.cff6ce0533a69p-1;
    x[0] = xm - xm*z;
    x[1] = xm+xm*z;
    w[1] = w[0] = 0x1.e539ec36e028ap-3 * xm;

    z = 0x1.13b23fd99b705p-1;
    x[2]=xm-xm*z;
    x[3]=xm+xm*z;
    w[3] = w[2] = 0x1.ea1da25aaa962p-2 * xm;
    
    for(int j=0; j<=3; j++) s += w[j]*swit2_(x[j]);

    return ((uint32_t)(s*2277.4239655685828));
}

There you go.  Much nicer to not have any of that silly for loop garbage in there when you're just multiplying through by some constants.

But next month will be funny for Magi when the first Skylake CPUs come out
Skylake is going to be quiet game-changer for X11, Quark and other non memory hungry algorithms. Just imagine AVX512 rented on demand! Well, the market already priced that in with Litecoin Smiley

the problem with that coin is that if the hashrate goes beyond certain values the block reward decrease to very low value

I know.  There's a great prisoners dilemma in coins with this type of inverse-hashrate block reward (Primecoin, too).  It's quite funny.
Yes, the question of how and when attack the blockchain is game-theoretic Cheesy

may-be I should buy it  Grin
... just to pull underpriced offer from the market Wink

Indeed.  I don't think I've seen quite as poorly-thought-out a design choice in an altcoin in a while.

Attacking this blockchain would be trivial.  This is *one* machine using my code:

Code:
[2015-07-06 11:33:26] accepted: 407/408 (99.75%), 793.46 khash/s (yay!!!)

A single AWS c4.8xlarge is a little faster than this.  One could double-spend Magi for about $30USD/hour.
which is rather expensive considering you won't make that much

It's true.  But the design discourages the hash rate from going up as the value of the coin increases, which is exactly the source of security in bitcoin -- one might suspect that this would just as likely cap the value of the coin as anything else.

At least it helps answer the question of whether it's worth implementing it on a GPU. Wink

But next month will be funny for Magi when the first Skylake CPUs come out with Intel's SHA extensions.  Easy ~2-3x speed boost to the miner once again.  Pretty soon there will only be enough hash rate headroom for a single machine to do all the mining.  And then we can rename it "central bank coin".  Has a nice ring to it. :-)

I'm happy to raise the price if that makes it more interesting. Wink

I've found two blocks thus far on my little i7-4770.  Not too bad - it's actually power-profitable, though not hugely so.

Oh thats nice with the i7
Nice to hear that Magi is power-profitable.
Magi likes to grow step by step.
Value will raise in time.
