ETH - Different Earning Estimations?

[virtualgoods]

My estimated monthly profit result of 22004 MH/s on cryptocompare.com is $62005 but in ethermine.org ( where I am actually mining via claymores) it says: $45006.97
( no electricity added)

Can you also compare and verify this? Or is there a problem with my rigs? I don't know.

I constantly get these warnings on logs every minute. Maybe this is the reason?

Ethermine is a really weird pool, try to switch to Nanopool. This is the one I use. Moreover there you will get an estimation based on what hashrate you are sending, so this is the most precise you can get.

Do not trust estimates, today you are earning $456 per month, tomorrow you will be earning $400 per month, the following day, you might be earning $320 per month, in the end of the month you end up with $150 or so. Difficulty increases too much every day.

I just wanted to understand if i have an problem in my rigs.

That is just a watchdog, it checks if all gpu's are doing okay, that is not a warning.
