Sorry, what?

Binance came out of nowhere with massive fake volume, as a China-based exchange pretending to be based in Hong Kong. They've proceeded to thrive by having a reputation for giving accounts to anyone, globally (which, TBH, is not a bad thing as they operate in countries where it's better than trying to save in the local currency). And their home country is "somewhere you are not".

There is no basis for believing that they have maintained all the funds: why would they?
