it's too late for the Clintons opinion of Bitcoin to make it do a policy U-turn.
Not too late to start WWIII though if she wins. In which case Bitcoin is dead, among other things.
The $10 drop yesterday is probably related to ECB telling EU regulators to tighten up control over cryptocurrency and congestion in the Bitcoin network with 20K transactions pending unconfirmed.
Its highly probable that a big chunk of the selling was caused due to the huge number of transactions in the pending unconfirmed list.
