Why does your platform need the Arty Coin token? What am I gonna do with him? After all, the purchase of tickets will be in dollars?
Absolutely all operations in the middle of the platform will be held in Arty Coin, this is the currency of this project.
Only this fact is obliged to keep the value of Arty Coin, I think that the price of the token is obliged to grow only if the platform is populous.
