This is really easy and one picture will take you 1 or 2 seconds. I actually can make $1.5 per day using only phone. With PC you can do this fast as hell using keyboard! I recommend this very much.

Remember, when your accuracy drops lower than 95% they can ban you so don't make mistakes. You will have to pass tutorial and exam first so do t worry. After first day you will be able to di it very fast.
