Looking at their MVP, the prices are quoted in USD. Now I do not now whether it will be local currencies for other countries, but definitely not in plex i guess.
PLEX will be one of the currencies on the marketplace that users can display prices in and purchase goods or services with.
In order to promote plex tokens, will you buyers some benefit so that they make payment through plex tokens?
For all transactions made using PLEX, the buyer will receive 3% cashback and the seller will not be charged any processing fees. This will encourage users on the platform to use PLEX instead of BTC, ETH, LTC etc.
