Well as I already said, there are multiple ways to earn online.
Ptc, Payed to click:
You become free member on a site and you click and read link.
After some time, 10 to 180 seconds you get money on your account.
By buying a membership this amount each click can be increased.
Ptrm, Payed to read mails:
You become a free member and you will get e-mails to your e-mail account.
This usually is the account you used to subscribe, but this can be changed.
The mails contain a link where you have to go to. Wait until the timer is 0, and click the next mail.
Advise
Create another e-mail account. Some sites will send spam or won't stop when you have deleted your account.
So just to be certain, it might be smart.
Also, especially Ptrm are mailing a lot.
I am with at least 5 Ptrm and I get around 300 mails a week.
Surveys:
Surveys are lists with questions. Depending on answers and the time you took you get money or points.
Points are also worth money. This is the best to do if you live in the USA.
They get more mails and most sites are only possible for US citizens.
And revenue share:
Revenue share is the only program which requires investing.
This is also a lot of profit without a lot of work.
You are capable of creating a free account, but to stay active you have to surf an X amount of sites a day or a week.
If you have invested something, each week you will get a percentage of money which you earn.
Usually this is around the 13%. You have to surf some sites a day, and if u don't you will earn less.
90% if you surf 6 days, 80% if you surf 5 days etc. Until 10% if u don't surf at all.
Each week it is possible to take 50% of your earnings from your account without penalty.
If you take more next week you will earn less.
Example:
You invest 200$.
You surf 7 days a week for 2 weeks.
200x1.13=226$ after one week.
After the second week it is: 226x1.13=255.38$.
