What is PTC?

PTC stands for Paid To Click. The basic idea is that you click on a link, wait an allotted amount of time, and then have some more money in your account on the PTC site you signed up with. The most common settings of this are that of $0.01 and $0.005 cents, and 10-30 seconds per ad. Usually there is either a confirmation code or some other means of showing that the click is done. Sometimes there isn't.
A good example of this format is bux.to. However, it is not recommended that you try and make money with bux.to.

Two other ways of making money online are through PTR (Paid To Read) and Paid To Chat (... this needs a different name so the acronym isn't PTC).

PTR is usually subscribing to having an email sent to your inbox, which you then click on the link to verify that you got the email, or to wait for a few seconds or minutes (like with the PTCs) and look at some website. You then have more money or credits or points to your account.

Paid To Chat is less common. myLot, however, is a good example of this.

I will not be posting my progress of PTRs and Paid To Chats on this blog; instead, I'll be making two seperate blogs for those.
Changed my mind. That would be unnecessarily fragmented. However, I will distinguish between them so as to avoid confusion.
