The most interesting thing of paymon is that it will be build on DAG. A system like tangle of IOTA but with some improvements. There are a few coins based on DAG like nano, byteball, radix, Oyster, IOT and dagger...
Paymon will be build on rust, which is the most advanced language IMO... and Paymon will be quantum resistant, a very important feature for the future..

if all this is really done, paymon will become a big player IMO
