Dear mmm01: We have notified Stephan, he will answer your question shortly.
Dear canth,
Trestor Retail Partners (RPs) are simply trading a 'token of subjective value', other businesses are able to trade various other similar tokens like old coins, artwork, stamps, etc. without any special trading license. In case of Trestor RPs, token happens to be 'Trests'
The fundamental difference between Trestor RPs and MSBs is that while Trestor RPs are traders of tokens, MSBs lets a user deposit money and assign it to another person for withdrawal, therefore they are participating in money transmission and generally charge a transmission fee.
