I never tried this exchange site before but it seems legit because I found a thread with the same question check it here
https://bitcointalk.org/index.php?topic=3168670.0According to some reply that they already traded on the exchange without any issue so the site might be legit.
However, if you are planning to exchange your coins in Coindeal exchange I suggest you deposit a small amount first to test before you exchange all of your coins.
Another information that I got is that the site doesn't have owner's information and the owner of the domain seems 2nd hand owner and I heard that someone experience delayed deposit and withdrawal confirmation. So for me, Coindeal is not 100% safe.
it is not a matter of trading or deposit, it is a matter of vote competition, token ents are being disqualified, then the coindeal tweeter passed in the winner of this competition token is ....
directly there is a picture of desaing this token releasing in coindeal, instead of being strange it might be possible to make a payment via the coindeal admin
