I guess they don't consist of fake teams. they ran away with money from investors and traders. initially, their site and platform looked convincing. they pay and everything looks fine. but after all, is running and more people are depositing money on their platforms, then it all happens.
There is no point in telling about it at this time, because they already had the intention from the beginning to deceive many people when their exchanges were already being used by traders and investors, their website was closed and their telegraph lines were gone too, so what what's the point of discussing this repeatedly?
There was still a possibility for them to get caught by the police and did you see what happens with plustoken scammers recently? They have been getting jailed by the chine police and it's still possible to make the all getting jailed too as long as investors can create a report.
