If you send ETH from an exchange to any ICO, you will not receive your tokens. This is because when you send ETH from an exchange, the exchange sends the transaction from their pool of ETH, not an address specifically linked to you.

When the ICO smart contract sends the tokens back to the address you paid with, it sends it back to the exchange’s pooled address so you don’t receive your tokens. That’s why you must always send from an address you control, not an exchange address.
