I think the bitcoin price will stay at the $650 level for two more months. Then it will rise to $800 to 900.
That could happen. I think the bitcoin whales are waiting for new release of the software before pushing the price higher.
I think the bitcoin whales are buying the Ethereum now, especially the ETC. The price has risen a lot today.
ETH has become one of the world's rapid altcoin. moreover bitcoin is currently stagnating prices. bitcoin prices are very slow moving. only $ 5 and never more than that.
