It isn't false.
Money doesn't just disappear into thin air. It's "owned" at all times. If you currently own 20% of the book value of your investment (notwithstanding the correction made below), then somebody else "owns" the other 80%. It is therefore currently sitting on the balance sheet of a private corporate entity which I presume to be the ICO issuer. I'm also assuming it's manifesting as an asset, not a liability, otherwise you'd be waving share certificates at me in your response instead of empty rebuttals.
Could well be that I have the aggregate ratios wrong. Thanks for the clarification !
Do you know that smart contracts can be the ones owing money?
80% of funds raised above the 250k ETH are being put into a smart contract that no humans have access to.
