I have XMR withdrawal issue as well, it is already second time. Coins are NOT credited back to account, so I even can not repeat withdrawal attempt...

Can someone from MinerGate check the case or point to appropriate support channel?

Seems like MCN payments are staying unconfirmed for the whole day now. Is there an issue with it?

From Minergate's Terms of Service:

" Minergate.com is not a wallet or custody or any financial institution in any aspect. Pool operator is not responsible for any loss of caused by any reason while working with the pool. Cryptocurrencies carry a high level of risk, any kind of losses caused by the third party activities has to be handled by the user.

Once coins have been sent from the pool it is up to each user to track their coins and ensure payment details are correct on the site. Transactions can not be undone by the pool."

So yeah, say goodbye to your money...

anyone else getting : ssl_error_bad_cert_domain  ?

Well why is it that after mining for a day and a half. I am averaging about 0.0005MHASH/BTC/DAY about 1/10th of what other multipools are paying out.

Either that or my stats are frozen.

The owner is most likely skimming profits from everybody

Has anyone else lost his btc in hashcow. I had .07 confirmed and today i only had .005

Sigh, I'm not going to explain. Read this for example: http://coinshift.com/about/

Oh I forgot to mention, that my rig has been pointed to HC months already. It's just this week's a bad one I guess.

What you've just described is a 3 user pool.  Assuming you meant 1.5GHs instead of 1.5MHs, thats almost exactly what we're doing now (1.5GHs switches), which still can't keep up with coins under about 2-3 difficulty.

I have a conceptual question, following on from the observation that the profitability of any pool seems to be inversely proportional to its size..

First just want to say I have a huge amount of respect for PoolWaffle, I have no idea how to set up a pool, sort out the coin switching, keep track of the payments, ramp up the pool hash rate steadily and evenly to be I think the biggest switching pool on the planet now, keep on top of the support and be nice about it. Chapeau, as they say in cycling..

My question ...is there a "right size" for a coin switching pool ?

If you are small, you can hit very small profitable coins, run the risk of forks, orphans. A skilled operator has the potential to be extremely profitable. If you are very large then you can't hit the small coins instead go for a steady income on the larger ones. If you are too big then even if you try to hit the small coins as well, and you succeed, you won't actually make much difference to the overall profit per mh since the fraction you can devote to these is negligible in terms of the mh of the pool as a whole.

It seems pool size is a bit like an investment strategy. High risk of high return versus low risk of low return, and this is implicit in the pool total mh. To mitigate this perhaps PoolWaffle could make the risk selectable in terms of the mh submitted by a user, say a score of 1 to 10. This would make everybodys payment different, but would allow the risk profile of the pool to be set by the users. The whales need to be conservative because they consume enough electricity to power a small town, whereas the smaller hobby miners might like a flutter, some may not. Profitability versus mh risk score would be very interesting, and again mirror what goes on in the investment world.

There would be a limit on how much high risk mh there could be, but if we assume that people like sfire need to be conservative, it might actually work out..

(disclaimer - I'm not in the financial business !!!)

I'd rather not have 48 tiny transactions per day sent to my wallet please, it increases transaction fees when sending the bitcoins again to an exchange or buying things.

Also: As usual, we've got 2 withdrawals pending at Cryptsy, one from late last night, one from this morning.  As this has become a pretty standard thing, it looks like their hot wallet runs out overnight, and someone refills it mid-day.  I'm not nearly as worried about it anymore, and it just means that payouts on average will be later in the day (same as the last few days).  With me requesting withdrawals early in the day, them arriving later, and running payouts when they come through.

i agree with that after that guy came in eveything torn apart

im switching to clever mine till waffle sort things up...
this is not good nor profitble pool until fix it once and for all

Rejects should be fixed on other endpoints (was bugged, is fixed).

We've been trying a ton of changes to increase profitability without a ton of luck.  We've got another test running right now (specifically on eu servers), hopefully that gives us some movement...

Essentially the problem comes down to orphaned blocks.  I think a lot of it has to do with almost all of the profit-switching pools acting very similarly (we all see some coin as profitable, we all switch, and block times due to the increased hashrate are closer to 5 seconds instead of 60).  This causes everyone to get a ton of orphans.  I assume its a problem on the other pools as well, since we're almost all pretty close to the same profitability (within 10-15% usually).  And this is with us sitting at about 30% orphaned blocks.

We've tried better connectivity, but we're still seeing a lot of orphans.  I've got a few more tricks up my sleeves, but the problem is, each of them requires a couple of hours of coding, and a couple more hours of waiting to see the results (and the results can be skewed by luck).

Long story short, not a simple problem.

We've got a few more blockchains synced, should see a few new coins pop up here in a bit as a gap measure (manually traded).
