Primecoin

There are many markets but if you choose only one of them as a common medium, exchanging Earth Hearts is much easier around the world. However, if you choose two there's an interesting outcome for collectors.

Primecoin and Terracoin have unique qualities which make them both useful: XPM is public, open source, and has long term support since 2013 while TRC has privacy and instant settlement features and establishment since 2012.

I wrote a website to demonstrate one-step swaps between Masternodes with Primecoin and Terracoin using Google Forms.

Does anyone want to trade gold for Primecoin? I have gold.
