Fake news affect bitcoin price ddown
Bad news affect bitcoin price down
Whales maniiptlation affect bitcoin price down
And especially volatile fluctuations
All the above are basis why bitcoin price falling down according from people analysis
But until now there nothing to proof how really true that is the main reason of bitcoin fall down
For me the reason why bitcoin fall down because is affeted of world economic crisis
I also read that the world economic growth will be at a standstill in 2019, which is not good news for the digital economy. Hopefully, people will keep using cryptos to prevent their decline at a very crucial time.
