Are you sure, that it's not a fake?
As far as I heard, Soros said recently that the crypto-currencies won't finish well and sooner or later they will die.
he had changed his stance on bitcoins and this shows the potential in bitcoins as such big investors are entering the community at high price levels. When he starts investing, I am sure that the prices will push to $15000 withing 30-45 days.
It is really a good news for bitcoins ad the people who were earlier against bitcoins are now supporting it. I will be more delighted if Warren Buffet also joins this group. He is the only authority figure who is still on his stand against bitcoins.
