One has to wonder if this is some way to scare folks away from crypto currencies. We know gold and silver are suppressed by the use of etf paper derivitives. This has been the way the banksters have contained any competition of the dollar for years. Now along comes crypto currencies which are a direct threat and no way to manipulate its exploding rise price, or is there?. Maybe this cyber attack is a new tactic by the criminal banksters to keep people from viewing bitcoin and others as a legitimate alternative. There is a new threat as it seems this wanna cry hack has morphed with computers coming up with a popup message and crawling speeds.
Keep an eye on this one.
