and why most of russians are scammers?
because most of russian are anomalous started from poorest man in russian to there president. there main thought is to hurt someone and make bad things, not only here, in every business, in every jobs they are making, they only thinking only in one thing, to hurt someone.
I know I'm replying to an old reply to an old post but you must either be trolling or extremely racist (stereotyping, ignorant what have you..) to even say that.
Anyways back on topic in reply to the OP, I don't at all think that most of the BTC scammers out there are Russian or a single national identity for that matter. Remember that Bitcoin was made with anonymity in mind and for me I think that it would be hard to pinpoint the identities of anonymous scammers.
I think it's to be agreed upon that there are lots of Russian HYIPs out there but what do we call the HYIPs which are "non-russian", not so easy to classify right without giving bias? Russia has a very distinct knowledge that makes it stand apart from all the "English" HYIPs, this might very well be the reason why they stick out more.
