Russia has not banned anything. This summer they must pass a law. I read the bill, there's nothing about bans. They want to limit the contributions of private investors, but no more. The US this year also promises to pass the law, but they act very carefully, that there would be no panic. I think that everything will be fine.
Yeah, sure, everything will be fine except that the government has set a limit to the individual contributions, so they are effectively telling you how much can you invest with YOUR money.
