It's a approximate number. The exact number of DLT you get is based on the actual price when they sell your ETH.
I got 0.50 cents buying with NEO
Do you know when Agrello will be released on an exchange site and on which one?
Aprox. 14 days after ICO is over. Which exchanges it will be nobody knows yet.
Actually there is one that is know, Jubi will list Delta once the tokens are issued

its on HitBtc now. You can see it in your wallet
DLT tokens absolutely are not on "hitbtc",
they do not even exist yet! Those are paper promise-bets from that exchange.
As stated above, you will be able to withdraw DLT from your sale wallet after the audit is complete.
