Why do you conduct tonen sale on your ouwn site but not IEO on exchange?
Because this is a coin sale, not an IEO
But conduction of IEO on the exchanges guarantees listing after the and of the token sale. Miners must be sure that than will be able to sell all mined tokens.
The problem is that many projects after tokens sale do not start the listing of tokens on the exchanges and investors can do nothing with such tokens. How can you guarantee that you will start listing on the exchanges?
