Have you heard anything about RavenCoin mooning within the next week or two.
There was a rumour that the team will have the event and they are going to present something that will make it grow 5-6 times in price?
Or is it a fraud?

It's not seems to be a fact. Because even the bitcoin price will reach the moon,when the demand of bitcoin is increased .And 5-6 times is totally seems fishy. Because even the bitcoin will not increase 5-6 times next week or two week.
So please avoid from such things. If anything say like this, most probably it will just to get some investors.
