Not worth it. The tasks pay $0.006 so if you manage to do 100 of them in one day (you won't) that would be $0.60. It would take you a month to earn $10.
But the worst is that most advertisers reject your submission and you get nothing. You can complain to Timebucks but they always side with advertisers (even if you have proof/screenshot that you've done everything correctly) and warn you that they will delete your account and keep your earnings if you keep complaining. I got cheated out of payment many times.
Don't waste your time with this.
