The price has dropped by around 500 Satoshis, it's based on pure speculation,  traders don't know wheter to buy or sell at the moment.

I have worked on and know what is coming on the next few announcements. I am not obligated to post about it yet until it is announced,  but I can assure you this. All those who've sold in the last few days will be regretting their decision to sell at such a low price.
