Assuming you complete your daily checklist, receive your activity bonus and receive the clixgrid add-on bonus, you will get a 16% total bonus on your earnings for the day.
If you get the 16% every day, all you need to do is earn $0.30 in a day and you will make $17.508 as you bonus for the year (which is a $0.508 profit)
And that's if you make THIRTY cents a day. More than likely, you already earn more than that daily.
If you earn $1 a day, you will earn a bonus of $58.36, which leaves you with a profit of $41.36.
If you can commit to earn $1 a day, in 1 year, you will have earned yourself a nice dinner out, a tank of gas, whatever you would use $41 for.
I believe it's worth it.
I upgraded on September 25th I believe and at the rate I'm earning, I will have earned my original $17 back by the end of this month - any bonus after that until Sept 25 2016 will be pure profit.
