Price per MAG should be 1 USD, so as to be able to work better the commercial use of Merchant Tools, this would bring a lot of value to MAG, it would certainly go up higher, I believe that 1 USD can start to be seen at the end of 2019 or in 2020, is the which I hope will happen, very good design.
Actual use of merchant tools can be seen on preybox.com, it's a nice site and the MAG plugin is great for the virtual market
I did not see any currency using this system model
