So is this a scam?
Absolutely yes it is a major scam.
The Monaco CEO was running a company called "Ensogo" as its CEO a couple of years ago, it went bankrupt and was under investigation by police for fraud in many countries.
That's certainly disconcerting. However, a bankruptcy in itself doesn't really mean anything. Vast majority of all the companies that Donald Trump ever started ended up in bankruptcy. A risk of failure (including the bankruptcy) is an inherent part of any business, it's even explicitly stated in the business legislation of any normal country. Being
investigated by the Police in itself doesn't really mean anything either. Anybody can file a criminal complaint against anyone/anything, the complaint can even be entirely anonymous, and the Police is legally obliged to
investigate it. So anybody can anytime be investigated for anything. If you recognize the Police then you must recognize the whole legal system in general and one of the basic legal principles is the presumption of innocence so you must recognize that, too. If there was any conviction verdict by an independent criminal court in any matter related to MCO that would be a wholly different situation, though.
That being said, information in this thread are disconcerting and the way MCO is (not) dealing with them is disconcerting, too.
