Is there any way to buy some ammo now?

I'm reading through it. One more question tho - If the users with nodes earn XBY, where exactly does it come from? Since all the coins are held by investors, how does that work.

Thanks for the fast reply. Just to clarify, the total supply is 650M and won't change in the future?

I'm new to cryptocurrencies/blockchain so pardon me if my questions are stupid.
Some things just don't add to for me. You are talking about these static nodes, i my wallet it requires 0,5million XBY to establish one. Total supply is 650million. Does that mean that a maximum amount of people each having a single node is less than 1300 worldwide? What if the price rises and no single person even has that amount (apart from a few early investors)? Multiple nodes then are quite impossible? I'm sure I'm missing something, I'd be glad if someone could clarify.
Also a 100 XBY transaction fee is mentioned, what if the price of a single XBY goes $1+? Do you pay $100 for a single transaction? Explain these to me like I'm 5 please.
