A lot of 2 satoshis sell order were filled while only a few of 1 satoshi buy order was filled. Why ?

OK, I'm a miner and not a trader, so I'll let you in on the secret. Anyone buying at 1 satoshi can make a round trip through litecoin for profit. Suppose you spend .001 BTC to buy 100000 MRC for 1 satoshi each (.001 BTC /.00000001 BTC/LTC = 100,000 MRC). Now you convert to litecoin at the rate of .00000055 LTC at poloniex. Now you have 100,000 MRC * .00000055 LTC/MRC = .055 LTC . Then sell the LTC back to BTC: .055 LTC*.032 BTC/LTC = .00176 BTC. That's 76% profit in one round trip, and that's why so many people leave a standing order for 1 satoshi.

The .15% fee essentially doesn't matter. The only limit is the small volume of people too impatient (or not knowing the trick) to convert it themselves.

Lol. MRC to the moon indeed.

I also mined microcoin for the last 6 days until early yesterday. It was peaking in coins per block, network hash rate was down after the difficulty increase, and it had a nice exchange rate at poloniex. It's also a nice coin because transactions seem so much faster than BTC, scrypt jane doesn't slow down my PC nor does it attract the scrypt miner middle pools of the world. The trick was to sell for litecoin on poloniex MRC->LTC and then sell litecoin for bitcoin LTC-BTC. The recent litecoin runup made it more profitable than selling in btc (even at 2 satoshis), but with the low volume I would put in an order and wait sometimes a few hours to get a transaction.

5 days ago 195 khash/sec yielded close to 500,000 MRC/day, which converted to .018 BTC/day. Now it's only about .006 BTC/day even with the high LTC->BTC exchange rate. Alas I moved on to take a chance on the galleon launch after MRC fell below .00000055 LTC.

let's hope alcurex attracts some attention to it...

Sure. This config gives the best hash (up to 60Khs with some good 750Ti (Gigabyte or MSI brand)). If you use Win you should able to do more because you could overclock it. I use Linux so it is still impossible, except Christian gives us the ability to overclock with cudaminer soon. Grin

cudaminer -l T15x4 -C 0 -m 1 -H 2 --algo=scrypt-jane:MRC -o stratum+tcp://

I just finished up the math in my calculator. The reward structure for MRC makes it really hard to say how much one would be making day in and day out, but I managed to average that arithmetic series reward structure.

The N-factor is going to change to 12 on 4/12/2014.
With ~480kh/s (~60kh/s per 750 Ti) the average per day coin accumulation is around 1.1 million from now till 4/12. At the current price on Mintpal of 1 Satoshi that would be about 0.01 BTC/day. The current day accumulation rate might be closer to 1.5-1.7 million though which would be 0.015 BTC/day. Not too attractive at 1 satoshi, but if you can manage to sell at 2 satoshis that can easily be 0.02-0.03 BTC/day which is attractive. These rates will only persist for another month though. Profitability disappears after 4/12 unless exchange rate prices go up.

My calculations are in-line with yours if we could sell at 2 satoshis. Have you had any difficulty in the past doing so?

Exactly. And think yourself: if a coin is very profitable why only you know about it and nobody else? MRC is out of radar of whale miners because of its arithmetic series reward structure, big miners think they got a lot of coins and sell. Why keep while you can have another millions tomorrow? But look at the buy & sell order at mintpal. A lot of 2 satoshis sell order were filled while only a few of 1 satoshi buy order was filled. Why ?

Last but not least, FYI:

I also mined microcoin. I CPU mined HVC at the same time on 8 threads without much slow down before the GPU miners were out.

Sorry I misread this information. If lspci shows your card ID and dmesg won't tell anything, it's maybe because of your nVidia-driver? What kind of version did you install ?

I suggest to reinstall ubuntu and only install nvidia-driver from nVidia site. It is much faster to determine what causes your trouble now.

i recommend you got with Ubuntu 12.04
yes it doesn't look nice but its also the most supported for drivers and cuda.

We need bamt 2.0 64bit for NVIDIA. Cool

Can you specify which cards to run in ccminer? I tried the -d 1,2 and stuff from cudaminer but it was a no go. Would like to get 670 on one and 2x750s on the other. Seems to be a bit slow otherwise.

Thanks, but with two cards it's working without problems. But as soon as I plug in the 3rd card, I get the described error, and nothing works anymore until I remove the card (tested with 3 different 750Ti, so it's not a defective card)

show me your nvidia-smi output

As I already stated in my posting, nvidia-smi does NOT work anymore after the 3rd card has been plugged in. All I get is:

Code:

Unable to determine the device handle for GPU 0000:03:00.0: Unknown Error

Still don't like it much but it works. I will a shot at Debian when I have time and I will report it here. Btw if you prefer a BAMT-like solution for nVidia, here is it:

Interesting about MRC. I will definitely need to look into that coin for my calculations. What card do you mine MRC with right now?

For YAC I am getting 28kh/s total. 3.3-3.5kh/s per card.
For scrypt I am getting 2344kh/s total. 293kh/s per card average.
For HVC I am getting 28mh/s total. 3500kh/s per card. Weird that some of the cards go as high as 4400kh/s while this increased performance is not seen in other algos on those "faster" cards. Maybe CPU related?

For YAC my settings are
cudaminer.exe --algo=scrypt-jane -H 2 -L 2 -i 0 -l t64x1 -b 4096 -m 1

For scrypt:
cudaminer.exe -H 2 -i 0 -m 1 -l T5x24

It should also be noted that my calculations do include a marginal 9th 750 Ti in my main computer that mines once in a while when I'm not using my main computer for work or games. The impact on the bottom line of this 9th card is nominal. Maybe $0.50-$0.70 per day.

I have a bunch of AMD, from nVidia some 780, 680 and old 580. Just built 2 rigs of 5x750Ti to test and I'm amazed how cool it was and so little is the power consumption, so I have order 10 more. Maybe I will build a farm of 750Ti Cheesy

.
nVidia now has only upper hand vs AMD in scrypt-jane high factor (N>12), so no wonder you can't compete HVC hashrates with AMD people.

I always think scrypt coins are so lame so I refuse to mine them Cheesy

. And according to my calculation, you can always find a scrypt-jane or N-scrypt coin which is more profitable than normal scrypt coins.

To be honest I don't have time now to check every new coins which popping everyday so I decided to stick with MRCs for a while. Have mined over 100mil MRCs and still mine like crazy. Wink

I still mine MRCs for days because I like this coin. Btw the diff is low and my tips: don't let the exchange rate fools you. You could always sell MRC for at least 2 satoshis.

What is MRC? Microcoin?
Looking at poloniex tells me that selling @2satoshi is next to impossible...

I don't use poloniex much, so I don't know. The exchange I used for MRC is mintpal. Of course you can't sell immediately, if you do the diff will be not so low now. Just set a sell order of 2 satoshis at mintpal and wait. Wink

Mind if I ask you what your launchconfig is for MRC on the 750s? When I try to run this cudaminer is showing me Nfactor 14? Not sure why it isn't showing me 11?

I'm having a problem with ccminer. It crashes right after connecting to stratum (on any pool).
I've tested multiple versions of the ccminer and each one crashes.
The error log points to MSVCR100.dll. I have updated 2012 and 2013 c++ Redistributables.
I'm running on gtx 770, i7 and win 8, Any help?
