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?

Look at the RVN price on the current Binance, it has been pushed up quite high with a market capitalization of nearly $ 250 million, so a 3 to 4-fold increase means that its market cap will hit $ 1 billion. It will be able to enter a strong bull market like 2017, but I think it will be difficult this year.
