I want to try my luck too good luck to everyone and happy holidays .  
Edit.: My bad I think i didnt really read full option B . I started mining at july 2017 and got bunch of mixed cards as gtx 10xx series - basically 1063,1070,1070ti,1080,1080ti. I bought some of them few months ago when btc was still arround 6k ^^ but got them somewhat cheap. (Will post further later)
