Here's another one, probably the last cashout of the year.

According to my calculations, I made an out-of-pocket investment of $15590.85.
With this cashout, the amount withdrawn was...
$15750!!

100% ROI achieved

Of course, I have to consider the taxes Payza will charged to turn those $ back to € in my account. On the other hand, the dollar rose in value between the time I invested and the time I started cashing out, which means I'm probably in profit anyway.

Since I didn't take notes of the exchange rates during the various deposits I made through the years, I have no way to accurately calculate that, but it doesn't really matter.
It was my first PTC and the one where I invested more. While it was not the first site where I reached 100% ROI, reaching it brings me a special degree of satisfaction.
