Yes you can return your investments from Bitcoin without new investors, if you’re financially literate. Example: You could set up a trust fund with Bitcoin and Dollars in it and pull out your profits from time to time, and the trust’s value wouldn’t be lower than when you started it.
In that case the entity behind the trust fund is a new investor. Try again. Let's me help you. In a banking system you hold units of debt and you benefit when the debt is paid. So, no new investor needed. In a product, you hold intrinsic value and you benefit by satisfying your needs with that value. Again, no new investor needed. In a company you hold shares in capital. Capital produces intrinsic value or is itself intrinsic value, which you also can use for satisfying your needs. So again, no new investor needed. In the bitcoin system you hold units of that system, and the only thing this system does is store record about its own units. Hence, a system that exists for its own sake. How do you benefit from this without new investors?
Nice try, but one entity can be grantor and beneficiary at the same time. Yet no Bitcoin sold, no loss on the balance sheet and more fiat cashed out. That’s actually how El Salvador handles their Bitcoin and it’s a really smart design. You got proven wrong.
