I will prefer to buy tokens already listed
Its much better and safe because they have some worth and tokens are not issued can give you serious lost because these can go either way mean in big lost or never appear which is not good for investor
SHITPOSTERS ALERT. You two, OP doesn't care what you prefer, OP asking how to issue tokens before doing ICO.
There is no reason why you can't sell tokens that are delivered at a later date.
Agree. If you already have somebody who believes and wants to invest in your project, I don't see any reason why you can't deliver coins/tokens at a later date.
Reason is you sell only promises. Author can never deliver because he is technical not competent enough.
He can hire competent technical person? That would have total control over his coin?
not really
This is why so many ICO are fail/scam etc.
And what is all ICO's selling? Worthless tokens = promises.
