The volatility IMO is due entirely to the hard fork. A big player (likely miner) sold at 450 because they know what is coming.
Expect price volatility to be much higher for a bit whilst the market tries to understand the ascent of Classic over Core in the upcoming hard fork.
I think we get short term negative price action followed by a huge relief rally leading up towards the halving.
Be careful with leverage because I wouldnt put it past some rabid small-blocker-early-adopters to dump thousands of coins in a futile attempt to prevent miners switching to Classic (though that is now almost fait accompli).
'lel' to brg444, marcus of augustus and all those who thought they knew better than the market.
I think you got it backwards. The volatility was the result of main stream media attention to the threat of stalling growth of Bitcoin due to the shortage of block space. Now that it slowly but surely becomes clear that Core is getting ditched for Classic by the community, the volatility is getting less. Once more details emerge about the implementation path of Classic, you can expect a rally.
