Regrettably this month has been very bad for PTC. PPClix has had to announce a reset due to the amount of false accounts, people stealing money from the site, and just plain old problems. Also it seems that SmithBux has gone out of business right before I managed to cash out :(
Now I'm not saying that PTC is hopeless, but I am saying that, if you are going to invest be very carefull with how you spend. I know people that have made a lot of money with these programs, and there are a lot that don't make and even loose some. Just be careful.
