This is really puzzling. It looks like an exit scam, but rational people would realize that with so much money they would be hunted with great effort plus some part of their customers is quite IT proficient plus US based means a bit suspicious justice system and extraditions around the world. On the other hand else this would be shocking incompetence, given that they have had problems for a while and they probably have money to build several such systems in parallel. I have money there too, by the way.
