Latoken is know for using fake volume and listing bad IEO. It always look like they have a share with IEO project in scamming people.
A big possibilities that they are involved with projects who did the IEO's inside their exchange and runaway with the money leaving investors being scammed.
Vindax is known for listing shitty projects. They listed a lot of deflationary token last year. None of them had volume.
Bad moves that bring negative thoughts from traders and investors who used this exchange knowing that there's no liquidity and no actions inside.
I won't advise keeping funds on this exchanges, especially LATOKEN, because they will come up with an excuse to ban your trading account.
Hard to work that out once they've already comes up with issue to your account, freezing then banning is pain in the ass.
