Best advice is don't call it a crashed this what we called a correction. Well you just have to just HODL then divert your self on other thing get into vacation. Don't worry this correction is just normal for the market to be healthy maybe it will go down around 50%-70% but after the correction the price will go up around 150% - 300%. It will start around mid February upto May BTC will go to the moon.
Completely agreed, this correction was a must. Every time were going near the psichological numbers there are thousands of peoples who takes at least some profit from their holdings; we saw this at near 3k, near 5k and last time near 20k. This time dump is stronged by prolonged previuos growth along with regulations and big financial players waiting on the side lines with bags of billions to drow market as low as possible to enter for max profit. Enjoy the show; my guess is well have a dip to 5.8-6k and then go oposite with power.
