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^
A wise man thinks alike, I also believe that this is a usual happening what experienced earlier a lot of time. So that there s no reason for being panicked anymore. I think Bitcoin and other cryptocurrencies will be the future money and it will dominate the monetary world. Not only that but also Crypto world will be the most profitable platform for trading and investment.
So you have to keep patient for a while, You will certainly get a lot of financial benefit in the future. Bitcoin will regain its price value and it will dominate all the capital world. Don't think more, Keep yourself attached to this platform for the future purpose.
