Title: Be careful with Zenmine.pro, the pool has payment issues! Not the first time Post by: cryptoyes on January 14, 2018, 03:22:53 AM I've used http://zenmine.pro since July, on and off (lately I mainly use different pools for Zen). Zenmine.pro had 3 Msol/s, and lately 2 Msol/s. It's the 2nd largest Zen pool. Avg block time is about 25 minutes, so no shortage for payments.
I stopped using this pool and I'm leaving this here as a warning. If the pool OP wishes to do something about it then fine. He now has the opportunity to address it. There have been long time payment issues with Zenmine.pro which have gone unfixed, despite repeated reports. 1. if you're lucky, you can see that the pool doesn't pay because the reported hashrate graph for your miner shows zero, even though you can see your miner submitting shares and that they are being accepted (I even checked with tcpdump). You can then contact the pool OP and ask to be refunded. Good luck with that. It worked once for me about 2 months ago but I had to insist. Other times I just let it go. Happened about 4 times since August to me alone. Once was for a full day, on some hefty hashrate. 2. a far bigger problem is when both graph and tcpdump/miner show valid submitted shares and correctly reported hashrate, but the pay is below what you should obtain. This is what happened to me in the past 7 days. I decided to test Zenmine.pro again, and so I pointed ~10 Ksol/s for the first 4.5 days then ~5 Ksol/s for the last 2.5 days. Difficulty in the past 7 days has been between roughly stable 500k and 600k (you can check this easily if you install the Zen node software). Below is a screenshot of the miner on the pool. Sadly it only shows the last 3 days or so, but you can see I had ~10 Ksol/s, then ~5 Ksol/s. You can also see that the pool reported 0 hashrate for about 5h yesterday, which is again false, see point 1. above. I should have been paid an average of 10000/550000/2^13*11*86400 = 2.10 zen/day for the first 4.5 days, and then 1.05 zen/day for the remaining 2.5 days. In total I should have received about 12 zen for the last 7 days. Let's say 10 zen. As you can see in the screenshot below, I got 2.4 zen for the last 7 days, and 0.4 zen for the past 1 day (I note that in the last 24h difficulty was lowest, below 500k). Before you ask about "luck", keep reading. Some facts:
The pool OP should have fixed these payment issues ages ago and should have credited the miners without the miners having to come crawling asking for refunds and insisting there is a problem. Some got nowhere and took losses, then moved on. That's not fair! We, the mining community, have started to get used to being ripped off because "well, that's the game". We don't have to take it! Pool OPs hide behind anonymity yet want our money. They have the possibility and the means to rip us off but there is no trust system - no identity, no verifiable achievements, no verifiable references. Sometimes they have a few "loyal" fans or folks who claim they personally know the pool OP, yet they are all equally anonymous. Sometime they ask you to try their pool and decide for yourself, swearing they won't rip you off, and that they're different to the other pools ... just like all other pool OPs. Then it can be fine for the first month or few months, and payment issues appear later, and you may not even notice. Let's put pressure on pool OPs to start showing something more for themselves if they want our money. It's much too easy to be ripped off by these guys. I'm tired of it. https://i.gyazo.com/5fb083a584ad1aa52e9e4d143b14ab86.png Title: Re: Be careful with Zenmine.pro, the pool has payment issues! Not the first time Post by: cryptoyes on January 20, 2018, 03:14:01 PM 6.5 days later and the pool OP (Ivan) has still not replied any further to my DMs or done anything. I also have some unpaid balance on his pool which I cannot credit to my account as he does not give you that option. There is also STILL some immature balance too from 6.5 days.
I just asked him once again to credit my account with the unpaid and immature balance and will not be using zenmine.pro again. Title: Re: Be careful with Zenmine.pro, the pool has payment issues! Not the first time Post by: cryptoyes on February 12, 2018, 12:36:49 AM A month later and nothing from the pool OP, despite contact messages on Telegram.
Stay away from this pool. In fact, unless you see evidence the operators are making money via other public means, stay away from all pools that charge 0% fees .. they are likely skimming hashrate.

I just mined ZEN on Suprnova 58109.22 h/s for 24 hours... Result: 6.24 ZEN earned Expected results: 7.86 ZEN earnings (source : whattomine) I know about the luck factor, but -20.6% is not bad luck anymore, neither PPLNS reward scheme... Moreover, this is not the first time I notice this on Suprnova pool, but this time I wanted measures straight! Sorry, I did stoploss and did not wait for a week... Conclusion: STAY AWAY from Suprnova as well!!! Any idea on a reliable and honnest ZEN pool ? |
