Hello , i have a gaming pc and i used to spend around 3-4 hours using it daily , i want to try using it for mining when i am not around ...
my PC specs  -GTX1080 8GB
                    -intel i7-5930k
                    -16GB corsair ram
                    -samsung evo 840 ssd 250GB x 3
                    -mobo sabertooth x99s
                    -PSU 1200W cooler master
i know some of these specs doesn't matter for mining , just to make sure .
single GPU is earning slow but as long as it's profitable , im in .
i would like to ask for some advice ,  what coin should i mine ( with better profit ) , where & how ...
i am only in crypto world for half years & have lost some money during trading .
Thanks for all reply and advice , appreciate !  

i've been in crypto world for just about half year . (i am not an expert on crypto)
normally i buy coins low and sell them when it reach higher value .
i'd make some profit but lost too
personally , i do not have much capital to invest , i am more to hard work for payoff
so i'd like to understand more about cryptocurrency bounty campaign & airdrop ... how does it work ? how to make profit from it ? where can i find these task ?
i am here to learn  , Appreciate for every reply , thanks alot .
