Why the price of the bitcoin is falling day by day?

The Bitcoin which had reached all time high price of $20000 in the last year 2017 has fallen down to great extent in year 2018 .

It had started its journey with price probably 0.16$ in the year 2012. It came into everyones eye in the year 2017 due to its great spike of the price.

The price of the bitcoin started to fall and is dropping day by day due to various reasons like:
(1) Manipulation of the market by whales.
(2) Some of the countries banned bitcoin.
(3) Facebook One of strongest social media banned cryptocurrency ads .
(4) People started to sell bitcoin due to fear.

what do you think will be the price of bitcoin by end of this year ?Will it break the its all time high or not.

Please share you opinion

Thanks
