If they are giving 90% of this token away to their users, and the rest of them most probably are going to stay in the hands of CoinDeal itself, it means this could not be a most profitable token to trade with.
How useful will it be? It's literally written in their post, lol:
With CDL, you can lower your trading fees, vote for new coins, use CDL to trade on multiple markets, gain access to additional trading features and later on you will gain access to our social trading platform, and more! Also, staking CDL Tokens in your CoinDeal wallet will allow you to decrease your trading fees to almost zero!

You can sell them, trade with them, HODL them, or use their functionality in any way you wish - theyre yours!" - well, nothing to say more, if something is fully yours, you can dowhatever you want with it ;p
Hi! If 90% of tokens arent distributed by that time, we will share the rest among all CoinDeal users who have already received 100 of them! The market is going to be launched on 12th November, so there are 55 days left to claim your tokens.
