It must be remembered that 10,000 coins = 10,000 messages from one block, if you also actively send pictures or sound - even less.
You are not carefully reading the technical description of the coin, one user can send 10,000 messages in one unit and pay for it 10,000 Long block is limited not by the number of messages and volume of 64kB, if that is not done at the 10,000 different addresses at a time, but I think the average user is unlikely under. But you can send 10,000 messages in 10,000 blocks, or 156 messages using the maximum amount of 64kB across 156 blocks(The limit on the amount of data transaction is 64kB (max fee is 64 LONG).
I explain what I mean. Ideally 1 block every 2 minutes (sometimes more). This means that the network cannot create new coins for new messages greater than 10,000 in 2 minutes. This is already limited for generating a large number of new messages for new miners or network users.
