You ignored the entire point. So, I am going to make it easy for you by asking you one simple question: can anyone in the bitcoin scheme benefit from the scheme without new investors entering the scheme?
Yes you can benefit from it since it is NOT a storage of wealth like so many idiots in this forum believe, but it is a decentralized currency that you can use to send payments.
You're supposed to explain HOW holders can benefit without new buyers - investors, not talking about concepts. Try again.
