Hi all , thanks for reading my question.

i recently got very interested about mining and start reading forum/article to prepare my own rig.

i currently have a GTX 1080 & Radeon R9 290 , can anyone share how do you "Scan" which coin to mine will be the most profitable?
the only thing i came across that somewhat answers my question is nicehash benchmark system.

There are also many "profitability" calculator online....but it is not like you know what is your hash rate beforehand to calculate them (unless u try them 1 by 1)..

so yeah , i will be grateful if anyone can answer my doubt

Thanks in advance!
