My guess is hitting 10 000 was a milestone for a lot of people and it went as high as 11.5k+ earlier today then a whale sold off or something and here is the problem with a bunch of people who own a % selling.. they create a snowball effect and others panic and get scared and start selling. How low will it go? No one knows as for long term hodlers you have nothing to worry about : ). So just hold

It's probably just correction, which makes sense after we plowed through such a huge barrier at 10k. Honestly, I didn't think that we were going to make it past 10,000 as quickly as we did, but it just so happened that it was pushed to the side super quickly. Of course, with that strong of a push in growth, there is bound to be an fairly strong push in the opposite direction with corrections and people selling their BTC to drop the price and buy more later too. Whales rule these exchanges; I can assume that a lot of them were involved.
