For centralized exchange, I only used high trusted exchange and the most popular one , those are Binance and Huobi. And for the small exchanges, I use it only for sell bounty tokens. I did use LATOKEN a few year ago and everthing is running smothly, but I never been use Cointiger. Just becarefull use Centralized exchanges because they have full control with fund of user.
LAToken was used widely in 2018 when most of the bounty tokens are listed there because of the IEO. Bounty hunters are mostly the ones who use the exchange merely to dump, they know the tokens they got are going to be dumped too. Now that IEO is gone, there is no reason for project tokens to be there especially when it's easier to add tokens on swapping exchanges.
