[do not]

url: dicedice.net

this site does not pay out as it seems. i didn't wanted to deposit, so i used the faucet to gamble to 0.01 (minimum wd), and tried to withdraw the coins. the transaction process did not finish, and after refreshing the site my balance was 0 again, and no coins have been sent to my wallet.

there were similar problems reported in the chat box, but somehow they are gone now (deleted?). So, I would suggest that you do not deposit coins to this site. most likely you will never see them again.

Ok,

I wrote my own profit calculator for different alt-coins. But today, I realized that it might not be correct 100%. I checked a lot of alt-coins against public profit calculators, and it wsa always the same result, but one coin is different, and I don't know why. The formula for the calculation is simple:

Code:

diff.f = DIFFICULTY
hps = HASHRATE_IN_HASH_PER_SECOND
blocks.f =  (diff * 2^32) / hps / (24*60*60)
blocksperday.f = 1 / blocks
coinperday.f = blocksperday * BLOCK_REWARD

It's pretty much self explaining, except for the "2^32" which basicly means 1 in 2^32 hashes will result in a share. Now, this formula is taken from bitexchange, but it also works for nearly every alt-coin I tested.
Why nearly? Because as I already wrote it does not work for BitQuark. If you calculate with the current BitQuark values, it will result in a very low coinperday value:

Code:

diff.f = 630.30597469
hps = 14000000
blocks.f =  (diff * 2^32) / hps / (24*60*60)
blocksperday.f = 1 / blocks
coinperday.f = blocksperday * 2.5

This would mean, that I would get 1.1170445699 coins per day with 14MH and a block reward of 2.5 coins per block. But when you check low frequented pools (I found one with 17MH) you can see that they get several blocks per day. So what is wrong with my calculation? The only thing I can image is, that the 2^32 value does not fit all alt-coins (maybe due to block time etc.)

Is anyone here able to explain to me, what's wrong with my calculations?

hi,

I'm currently planning on buying my first scrypt mining rig, and need some tips with the hardware. so far, I have the following components in mind:

ASRock 970 Extreme4, Mainboard
AMD Sempron 145 AM3
G.Skill DIMM 4 GB DDR3-1600
3 x SAPPHIRE Radeon HD 7950

OS: BAMT from USB stick

alright, and here are my questions:

1. What PSU do I need? would a Xilence Gaming Series 800W PSU be enough for all three cards? Or do I need more? I was also thinking about 2 x 500WATT PSU and use them both with a dual PSU adapter cable.
2. Do I need powered risers? Or can I use normal ones?
3. Does anyone know if I can undervolt those cards with BAMT, and how much?
4. Is 1.8MH/s realistic?

Thanks in advance

Moin,

ich wollte mir erstmal ein bissel Geld in BTC tauschen, um mal ein Gefühl dafür zu bekommen. Auf meiner Suche anch Möglichkeiten das Ganze mit PayPal abzuwickeln, stiess ich dann auch auf die Seite VirWox.com
Nun klingt das für den unbedarften User ja gar nicht soooo schlecht, aber was letztlich wirklich daraus wird macht mich echt wütend. Hier einfach mal die einzelnen Schritte die nöltig waren, und vor allem, was man dabei alles verliert!

1. 50€ per PayPal aufladen. Es kommen 47.95€ an, der Rest ist Gebühr. Ich kann nicht prüfen was VirWox wirklich an Gebühr bezahlen muss, muss das also erstmal so glauben
2. 47.95€ nach SLL tauschen. Hoppla, gehen plötzlich nur ganze Euro-Beträge. Ergo 47€ werden getauscht in 14.864 SLL. VirWox greift nochmals 495,43 SLL ab!
3. SLL nun nach BTC tauschen. Das tolle: Es werden einfach Nachkommastellen ignoriert beim Kauf. Anstatt komplett im Nachkommabereich handeln zu können gibt es 0,074 BTC für 14.708,03 SLL. Achso, Gebühr wiedermal 463,10 SLL
4. Na, jetzt haben wir endlich unsere Bruchteil-BTC, wollen wir die auch gerne aufm Konto haben. Also rüber mit an unsere Addresse. Aber halt! Was ist das? Es wird gar nicht ausgezahlt! Das dauert bis zu 48h. Und ganz nebenbei kassiert VirWox nochmal 0.002 BTC für diesen großartigen Service!

Was bedeuted das also im Ganzen?

Wir haben 50€ eingezahlt, bekommen dafür (vieleicht irgendwann dann) 0.072 BTC. Auf unserem Konto bleiben Überhänge:

0.95€
~ 150 SLL

Wir bezahlen an Gebühren:

1. 2.05€
2. 958.53 SLL
3. 0.002 BTC

Total verlieren wir also durch die Aktion:

3€, 1108,53 SLL, 0.002 BTC und ne Ganze Menge Zeit! Ganz abgesehen von den Kursen die höchstwahrscheinlich nicht gerade zu meinem Vorteil sind.

Mein Fazit: Sollte ich auf die glorreiche Idee kommen nochmals BTC zu kaufen, gehe ich lieber das Risiko ein von nem Wildfremden verarscht zu werden. Da bekomm ich das Zeug dann wenigstens instant (sofern ich es denn bekomme). Aber ich hab grad echt nen Hals und würd am liebsten alles komplett Rückgängig machen!

Hi

I have a CubieBoard2 running cubian here, and I already have litecoind/litecoin-qt and dogecoind/dogecoin-qt installed. Hoewever, today I tried compiling the bitcoind and bitcoin-qt from github, but that didn't work. So I downloaded the tar.gz file, and I was able to compile bitcoind. But I still have problems with bitcoin-qt. After about 15mins of compiling the make process failed, and now I always geht the same errors spammed all over the screen when trying to run make:

I installed all pre-requisites as far as I know. Anyone had the same problem yet? Or any advice? thx a lot.

Hi,

is it just REALLY bad luck or is the doge coin system a bit messed up? Since three days I'm trying to get some coins, but all I get are orphaned blocks. The first pool I joined went down after a few hours, but at least I was able to withdraw my coins. So I switched to another pool. But even after 10h mining not a single coin showed up. All I saw was orphaned blocks and I got nothing.

So again I switched the pool and guess what? There are also a lot of orphaned blocks. My system isn't very good, and I only get around 130kh/s. So it really hurts when you keep getting nothing out of the pools.
Anyone else has such probloms?

Feel free to throw some coins at me, but at this point it seems a bit pointless for me letting my system run 24/7 if there is no reward :/

Hi,

I tried compiling cgminer 3.5.1 under cubian (based on debian) on my cubieboard2. However, compiling seemed to work, but now I can't start it. Nothing happens at all, I don't even get an error message.
After checking the file with the "file" command, I got the following info:

Code:

cgminer: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0x86184836c6cb8db8cc9cda04936e542c8da2abe2, not stripped

Anyone knows why it doesn't work? Or maybe someone also already had that problem?
