[UNRESPONSIVE POOL OPERATOR] 50BTC.com

[Acejam]

For some reason my cgminer client will crash whenever I try to mine with 50BTC. If I switch my connection string to BTCGuild, I can run for weeks without any issues. I'm mining with some BFL ASICs.

I am using the following command line in my batch file:
cgminer-nogpu.exe -o http://stratum.50btc.com:3333 -u myemail@goeshere -p mypass -G --no-submit-stale

(I have also tried pool.50btc.com:8332 as well, same problem)

Any idea why this happens? After about 3-4 hours last night I checked my mining machine and found cgminer-nogpu has crashed. I found that it crashed a few times last week as well. Then I finally realized it only happens when mining @ 50BTC. Thoughts?

In a post in the cointerra/bitmine thread, they mention the partnership with 50btc.  But they also mention in the same post that orders today will not be available until december.

How will orders at 50BTC get filled in october then?

I just tried that for the last couple hours. I then logged into my mining machine about an hour later and found this:

Acejam,

1) You will need to add the backup pool to your command line:
cgminer-nogpu.exe -o pool.50btc.com:8332 -u myemail@goeshere -p mypass -o pool2.50btc.com:8332 -u myemail@goeshere -p mypass

Every now and then one of the pools goes down. You might also set cgminer for pool load balance.

2) 50btc uses manual miner difficulty. Default is 1. At 74gh/s you should be 64 or more.
You can change it at https://50btc.com/worker/stats
The should be a small yellow box with a pencil in it. Clip on it and you can change difficulty. You can read more of this in the Help/FAQ section.

Good Luck

Thanks for the info. I have set my difficulty to 64 already and was able to see it coming down as 64 earlier - but when this disconnect problem happened it dropped back down to 1 somehow.

With that said, I'll try adding the second backup server - I didn't think of that! (Only thought about adding another pool as a backup)

Thanks!

any idea why both of my workers went offline?
no accepted shares either on 50btc.com, stratum.50btc.com or pool2.50btc.com
anybody with the same issue?

I use pool-de and pool-ru both are reporting 'Dead' in cgminer

I am struggling to understand the per share payout if the fee is 3%...

Per the 50BTC page...

1 = .00000027
2 = .00000054
4 = .00000108
8 = .00000216
16 = .00000432
...
1024 = .00027648

Assuming the 3% fee is taken from the top - 25 * .97 = 24.25 / Difficulty.  So the Calc for 1024 diff is here --> http://snipurl.com/50btcpps

That calc gets you 0.00028564

Something is not right here?!?

Ok, thats significant. I was using 512 and it appears that its off enough to count too.

50BTC admin, can you fix this?

It seems, since there are 8 digits to play with (but there doesn't have to be), that is they used diff1 and extended to 16 decimals (.0000002789503990) all would be fine.  If they rounded to .00000028 all would be fine (but then they would be paying slightly higher than 97% -- 97.365% to be more precise  ).

This is a simple fix and things will only get worse as the diff1 share approaches 1 Satoshi....

[JWU42]

Same issue with new diff  

Using only 8 digits diff1 is .00000021

Using 16 digits diff1 is .0000002153095310

We either need to round to .00000022 or start extending to 16 digits like other pools have.

Using .00000021 is paying 94.6% PPS and NOT 97% as they promote.  See--> http://goo.gl/VFwwiC

Pool Ops, whats the word on this? As of now you could almost do 100% PPS and just keep the rounding errors. You'd be getting almost the same fee judging by the above calculations.

Please extend to 16 decimals or feel free to round up.

3 days and no response

16 decimals patch is ready. It will be released soon.

[JWU42]

I am hoping soon is much faster than diff > 64 (that took weeks).

50BTC staff,

I see you have idle miner warnings....well, looks like you either had them or are planning to add them.

When I edit a worker I see:

Failure detection threshold (minutes)

However, that doesn't have a setting field. I've had miners go idle many times and I never get notified.

Please fix.

edit: yes, I have the check box checked in the account settings. Always have but it doesn't work.

Thank you.

[JWU42]

Payouts are locked?!?

[50BTC.com]

We're using 16 decimals now. You can test it yourself, simply multiply your share count on vardiff1 share price and you will be able to see the right result. (minus 3%)

Payouts are locked?!?

It's not. We were patching our servers with 16 decimals patch and you've probably encountered this problem because of this. It should be fine now.

This option is still in developing.

Thanks guys -- didn't look at the math yet but will now.  I was looking for the change shown in the PPS rate pop-up...

EDIT:  Confirmed it is using the 16 digit share value of .0000002153095310

Strange I have an auto payment sitting " In process " for about 6 hours.

edit: It just went to status " Refused "
