I've actually heard of what he sent me before, and although it could legitimately make money, chances IMO are not good. Although it COULD be very profitable 200,000% just wouldn't happen if all goes well 5,000% maybe.  Most likely you would lose it all IMO but same thing with playing the lottery.  In short it's legitimate  although the risk/reward isn't worth it IMO but I'm pretty conservative when it comes to investing.  For someone who likes very high risk very high rewards things like pink sheets it might actually be something for you just make sure and do your DD first and don't bitch if you lose it all if there were a sure way to make multiple thousand percent returns reliably everyone would do it.  Lastly I won't say at all what it is he asked me not to, and I will respect that.

Edit: IMO I said IMO WAY too many times sorry about that.
