May be associated and liqui stolen personal funds, then financial institutions began to sell the currency, led to the fall, but don't be afraid, now is still in a bull market, fell not gives us the opportunity to buy?

why? bitcoin is going down because they hit the 19,666$ and the price of it are jumped nearly 13 times according to my research, so that's why the price of bitcoin fell over 36 percent and losing more than one-third of it's price.

​​The Segwit2X hardfork will be held on December 28, all about the new Bitcoin fork. So servers are busy in current market. It is affect the Bitcoin value. In current situation all the miners are jump to altcoins only few of them are available in mining so transaction fees also increasing in crypto market. This is not a issue after hard fork it will automatically changed. Bitcoin value is raise gradually in crypto market.

Simply because the transactions are high at this moment. People are selling Bitcoin not because they are no more interested but rather they are in need of money because of the season. So eventually, its market value is expected to be more expensive. All we have to do s to hold and patiently wait.

I believe the segwit2x might also play a part on the drastic fall of bitcoins but altcoins are also dipping and bleeding seriously.According to coinmarketcap about 90% of altcoins are all in red and major decline in the entire market cap

My personal thoughts:
* Bitcoin initially went down due to pumping other alt-coins especially BCC (according to coinmarketcap with BTC dominance going down)
* Now (as of these past 2 days) people are panic selling due to them just seeing Bitcoin go down and not realizing it was just going into other cryptocurrencies
* Honestly, I don't know how far the drop could be, but it'll be pretty bad, BTC dominance is going up which is a sign people are cashing out for fiat currencies and not other crypto-coins

again- just my personal opinion based on speculation.

I think the past issues with the BTC platform that was left unresolved because it was covered by its popularity of the cryptocurrency  had caught-up with bitcoin.

According to Fortune,  the drop is a result of the fallout from long-unresolved problems with Bitcoin’s infrastructure,
and the increasingly intense civil war it has produced in the cryptocurrency community.

###################### WARNING ABOUT CRYPTOS ########################
The 2008 financial crisis caused 500,000 CANCER DEATHS!!!
  (If any doubt, just do your own research).

        9/11 WAS ### A JOKE ### IN COMPARISON

Who is mainly RESPONSIBLE FOR THIS CRIME? #### BANKERS ####
Have they been to JAIL? #### NO ####
WHY? JUST THINK.

##### NEVER FORGET THESE INNOCENT 500,000 VICTIMS WHO SUFFERED BEFORE DYING ##### (LIKE SHOAH)

Now, bankers & central banks are afraid to lose their jobs because of cryptos,
so they try to scare governments about:

1) their FIAT currency
2) losing control and power
3) losing taxes revenues

What they currently do is create ARTIFICIAL HUGE VOLATILITY on cryptos (they have enough funds for that).
They want an EXCUSE to "protect" investors.

In reality, they just want to take CONTROL (REGULATIONS OR BAN)

They also SCARE PEOPLE ON SOCIAL MEDIAS, PRESS, OR TV (CNBC for instance).

DO NOT LET THEM F#CK YOU AND YOUR FAMILY ONCE MORE.

WE DON'T NEED ALL THESE MOTHERF#CKERS ANYMORE.

===> ACCEPT CRYPTO PAYMENTS FOR ANYTHING INSTEAD OF FIAT. BUY MORE CRYPTOS. <===

NOW YOU KNOW. PLEASE SPREAD THE WORD. THANKS

I think its because today is end of the year going to christmas season and new year i think that was the reason why bitcoin was dump but after this bitcoin will go back to normal again.
