I don't think the FBI doesn't have to do with it. It is because that they also know what the risk of investing with those kinds of investment.
And they can't really run after them just to chase the people behind hash ocean.
Just learn the lesson from that incident.
even though the FBI would care about it and about cyber crime, and even though they would managed to caught them, there would be no chance people to take their money back.. so it's all pointless..
even they are caught by the FBI the money is still cannot be refunded because the only possible thing is that they have transfered it to another person and i don't think that the FBI would mind about this big scam it is just a fault of those stupid people who invested in hashocean

Nah, this is pretty serious. As people file complaints in various jurisdictions, the import will build to the point were the FBI has no choice but to investigate. Remember, they get to fine you if they catch you

they have a very large incentive to go after these guys.
No, you are on that bullshit ATM, you are spamming multiple threads with this.
Show us the transaction, if you will.
