We can rest now for some time because it looks like btc is "stable" atm, but one friend of mine was calculating the drop and he predicted this drop to 13k, moreover after that he thinks that it will go down even more, and by that "down" he means doooooown, so he sold his entire part. I hope it will not go so low in the near future and that this was "Christmas drop" since many people needed money for gifts/dinners/etc... and now we are floating in the safe areas. Some oscillations are normal so if you can resist than HODL it :)
I will hodl mine for sure...
