After reading the Whitepaper I have some doubts on the supply and demand of the coin. 100M coins will be created, is this number the total number of coins that will ever be created? And, when someone uses the coins to pay for the subscription service, these coins are burned or it can be sell back to the users?

I love the idea of concerts crowdfunding platform, I haven't seen that before, and I think it can upscale a lot!
