The DGB-qubit issue seems to still persist?
over the last few weeks i tested mph in comparison to nicehash with baikal miners, mph is more profitable on the paper 99% of the time, but the real payout in btc is by far less than the expected return and nicehash payout is in fact more
in return i have switched back to nicehash
i tested that some time before and at that time dgb-qubit was the culprit: it displayed incorrect estimates which where far off and thus the miner often switched to it for some time and then back to "stable" coins, might be something else additionally as well, all i can tell is that the profit is off by much (tested for 48 hrs)
It's because digibyte's difficulty value goes up and down toooooo frequently.
Here you can see difficulty history from Blocks page.
https://digibyte-qubit.miningpoolhub.com/index.php?page=statistics&action=blocksIt goes up around 463 and crashes to 147 for last 30 minutes which means profitability goes up like x3 for very short period of time.
It doesn't mean that you earn less always. You would earn much more sometimes but much less sometimes.
