What you are suggesting is a pyramid scheme.

You will pay the late comers with the money from the first ones.

There is nothing new here.

This model is illegal is any decent country. It is a scam and you WILL have legal problems, sooner or later.

Even if you find an exchange that would accept your idea and scam others with you it will fail someday. Maybe you can make some money from naive people, but authorities may reach you and shut down your business and get you into some trouble.
