I do not recommend anybody here participating in Latoken, P2pb2b, Coineal, Vindax IEO because you will get nothing in participating in their IEO.
Vindax had a problem with using different symbol and name to deceive their users, here is the thread talking about that
https://bitcointalk.org/index.php?topic=5173500.0P2pb2b is a well-known scam exchange, just type on Google you will find it.
Coineal deceived their investors and the projects running the IEO by controlling the bars of collected money.
Latoken is a graveyard, there are no buy orders there.
I have experience with vindax, i did not find any issues with it, trade deposit and withdrew have no issue.
