I sell my 5 Aorus TI xtrem.
There's so better and profitable things to do rather than mining today in crypto..

PS : It's really not so hard to find
Mining today in crypto is very very good profit.
But on one condition - if it's wise to approach the matter! But of course if you mining zec then any cards fool shit!!!
So in my opinion you made a mistake
Oh, you sure ?
We have not the same definition of the 'profit' term

How can I make 2500% ROI per year, and 6000$ month, without my PC powered on, and the heat of the cards ?

How many 1080Ti's give you 6000$ month ? An entire farm ? ^^
I repeat : there is VERY more profitable options than mining nowadays...
