I've heard them too. My poor grandpa's savings overnight dissapeared as a currency (soviet ruble) in a inexistent institution (he stored them in post...). Then there was MMM, 2 months obligations in russia, and other scam shit. In moldova a billion buccs swinged away from 4 banks 10 years ago. Also some insane amount of monis, like half trillion of rubles got washed from russia into other states.
