The nature of traffic exchanges have changed drastically these days. They bring more and more traffic to your sites provided you view and spend some time on their websites too.
I do not deny the fact that traffic exchanges are good. They are good in the beginning of the career of an online marketer. As and when his business grows it is better it he discards them keeping in view the potential buyers that do the trick.
actually I really don't have any idea about link exchange.
I dont think reciprocal link exchange is not the best way.
I think it is not good for your web page rank, social media marketing is better than from link exchange.
Traffic exchange's Traffic are not interested in your site or your Offer. They try to increase their points to get visitors to his own website or blog. but it has some advantage for PTC Sites. When anyone click on your link Cookies will set her computer. This is the main benefit to getting Credit from Traffic exchange sites.
