I don't think bankrupt is the right word here. It's the opposite. They didn't bankrupt themselves. Their scam was exposed at some point so they stopped doing it. They didn't lose any money. For what we know, the creators may have been quite successful in extracting money from its users, including Bertyar88.

So, the more interesting question to me is how much money BaseFEX actually made from this scam before they turned it off.
