Paypex has a special phenomenon that I haven't been able to understand yet. The product is of great value for the development of the economy in the world of e commerce. That's the truth. But the team did not conduct a large scale PR campaign, so that the project became as popular as it is now.
I did not fall for the early development of the project, but I observed the process of increasing the value of the token Payx. It seems to me that the simplicity of the application is what buyers and users of the purse want to see. I think that this potential is interesting for the participants.
