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.
The market can't always move and down a lot to please people as it will allow them to make profits in a short time.
We have had enough volatility before the block halving, and on top of that the price has gone up quite a bit as well.
Ethereum is going through a roller coaster for quite some time now. You can't compare that to the current Bitcoin market.
The Ethereum volatility will last until at least the end of August when the DAO hacker can move her coins.
