ill be thanksfull if someone will explain to me :)

I entered this forum (and not only this forum, alot of forums of other ptc sites.
everyone shares there stats and its just making you understand its not worth the time.
I see people on every ptc sites saying they have 7000 - 10000 RRs and upgraded account and its giving them in the best case anywhere from 40 - 80 $ a month! is it worth it to spend months and months to get to this amount of RRs and big account for some bucks a month? am I missing anything? im reading it wrong, can you make good money with 500 - 2000 RRs?

I really like this site and this site is the site that I invested the most (im new to ptc) so I just want to know more.

thanks alot my friends! :)
