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

Tha battle between traders, whales and the demand itself is what's causing the flactuation of prices, there's nothing that can predict the market except the flow of buy and sell. My BTC is stock for years and I will hold it till it is a 100k$. Trading BTC on the other hand is so scary because you need not to sleep to monitor the prices, the changes of dollars is terrefying every seconds. Without proper knowledge on trading you are just going to lose. Also I can't afford to lose anymore BTC. I have been trading it when the it's price is low but now? Man. Losing some BTC in trading is like losing a month of work. And I can't take that anymore.
