Feeleep are you there? Your pool has stolen my 200$! Can you help?

Hello feeleep. Yesterday I have been mining on your pool with top1 speed for ~1 hour. And no earnings have been credit. Can you check it? I have sent you an email from pool website with more details.

After changing pool to another one i getting stable more than with coinmine. 

My earnings with 4100-4300s/s are about 0.38-0.49 Zec/24h is it normal?
All calculators that i found across the internet shows me up to 0.57-0.62 zec per 24h.
There are more than ~25% difference What wrong with payouts?
pool nickname - andr15

SSL/TLS connection ?

You suck, it's not much. Renter cost hign over 30-40% normal ZEC mining cost with luck =100%, miners can dump for electric cost and go to another coins, but renters have to accept to lose by ZEC/BTC crash 10-20% rate(up to 30%/day). If you dont like, you can go to f2pool, flypool, nanopool

My earnings (and likely everyone else's except for the big pool-hopping scammer) in the past 24h now up by 85%. Partially due to pool luck of 57% in that period. The rest due to switch to PPLNS.
Win for 99.9% of miners, win for pool (miners like higher payouts), loss for the 2-3 scammers with the tens of thousands of GPUs.
Since these guys control appr. 10% of the global hashrate, they should make close to 600 ZEC per day. Until coinmine and suprnova dropped PROP yesterday/today those guys have scammed away from the loyal miners a couple hundred BTC total (or a couple of Tesla Model S P90D).

Thank you, I noticed that around block 24150-24160 things changed. Now earnings per round are much more consistent. Huge difference to before when they would scatter by a factor of 3. My daily earnings are already up by 60% and it is just 16h since changes were implemented. Part of this is obviosuly due to the fact that the pool runs at a sensational 60% for the past 24h. So in total I do expect revenues for loyal miners (that's probably the vast majority) to go up by 15-25%, while the three huge pool-hoppers (could have been just one splitting his hashpower on three accounts) will see their revenues go south.

Hi - I am currently testing PPLNS scheme as I noticed this miner as well.

EDIT: Payout scheme changed to PPLNS

@feeleep: I was wondering why my revenues on your pool are in total 15-25% less than what they should be. Until I noticed that on >100% rounds my revenues are just slightly below what they should be while on <100% rounds they are 2-3 times lower than what they should be! The further away from 100% the more discrepancy on both ends. So I monitored the situation and saw one huge farm pool-hopping.

They hop into your pool when a new round starts. If the rounds goes over 100% they hop to another pool. It is the miner which has appr. 3.5 MSol/s and is donating (so easy to spot even for outsiders, despite the anonymous handle). This means that once the round goes over 100% the hashrate of the pool drops from 7 MSol/s to 3.5 MSol/s and the rounds get very long. Once some loyal miner who stays in the pool finds the block and the round ends, the 3.5 MSol/s miner returns just to pump the shares on the new round, getting overproportional revenues on all short rounds, while letting others do the lifting on long rounds. Sucks, because everyone else is probably losing 15-25% on average since this pool-hopper has 50% of the total hashrate of the pool.

Any chance to switch from PROP to PPLNS to end this scam?

The pool works nicely otherwise, but this mega pool-hopper sucks and steals big time from the loyal miners. Don't tell me these are the GM scammers, because there are not many people out there able to do 3.5 MSol/s.

Can you explain in more detail on what port to connect legitimately?
At the moment, all of my farm go to port 7007:
Worker   Hashrate   Difficulty
001   1,441.68   21750.23
002   988.20   13005.43
003   930.12   13698.45
004   899.57   13248.45
005   502.54   12433.91
006   381.98   9087.54
Does it make sense to change the port in my case?

hi - it is only automatic at this moment, I really (REALLY) dont want to keep users coins on pool wallet

you should consider dropping payout limit to 0.001 like most other pools bro.

thanks guys!

Best zcash pool , actual hashrate, automatic payout 

Thanks for adding static ports, ur pool was one of the more stable to mine zcash, u did a great job. Thank you. 

Guys,

Small update and summary on changes in pool infrastructure:
I added several failover servers in US, EU and Asia to keep the best possible performance for users (no disconnections, no issues with authorizations, lowest ping possible). I had to restart stratum servers but it was last time
Because I had a lot of request I added two static ports and here is a summary:

Available addresses:
zec.coinmine.pl - geolocation, load balance, failover - use it to get the best possible ping for your location
zec-eu.coinmine.pl - load balance, failover - if for some reason you want to mine directly on EU servers
zec-us.coinmine.pl - load balance, failover - if for some reason you want to mine directly on US servers
zec-as.coinmine.pl - load balance, failover - if for some reason you want to mine directly on Asia servers

Available ports:
7007 - default vardiff port
7077 - default vardiff port for big hashpower
8008 - static port - diff 20
8088 - static port - diff 500

Any questions? please ask
