Do not panic, because this has happened several times before and it always bounce back from March onwards. If you look at the other Alt coins, you will notice that they are also going down, so there are not a new movement from Bitcoin to other Alt coins.
I cannot substantiate my claims, but I think some Fiat whales are slowly dumping coins to manipulate the price. I cannot pinpoint the motivation behind this, but I know they are slowly cooking the frog. ^hmmmmm^
This is true. It happened already many times, and those guys who are on the market for several years should remember these crashes. This is a temporary situation. Close to March I hope the market will recover.
