zpool is notorious for paying 30% less, you will make less than whattomine known coin, it's better to mine lbry or zcash with your card, also skein2 is bugged with the diff retarget that don't work in case you want to know
ok, you say this, based on what evidence?
The estimates given that are based off the market which has serious swings in coins (let's say an average of 10-30%?) seem like just a coincidence?
Also; zpool only uses only a few exchanges, so it doesn't have the error of other exchanges that could or couldn't get that sale, plus the human factor involved as well....
Just because your early-on "ESTIMATED EARNINGS" wasn't what you got paid in the end; doesn't mean the pool is ripping you off man. The pool will see its generated coins for whatever price it can get to pay its miners; which means fufilling buy orders at lower than market rate sometimes.
You have to think deeper into what you don't fully understand.....
I personally have yet to be shorted by zpool. Any time a payout never made it or was delayed; it was handled.... as long as it was a controllable aspect. Obviously if you chose an altcoin for a payout and didn't tell the pool that in the password field... and the pool sends a payment to the BTC network instead because of this; it's not the pools fault, nor can the TX be reversed. That's just logic.
When I see dips in my earnings (such as a few days ago) you could clearly see that DGB and AUR lost nearly half their value in the matter of hours. is the pool supposed to magically credit you for the losses in the exchange ESTIMATES? That's silly to think that way.....
There's logical explanations if you do the legwork to find out why; instead of just randomly speculating and pointing a finger at the closest person/thing.
