The price of bitcoin is unpredictable, is it completely affected by the whales? I read some article from coinmarketcap app, that a whale drop lots of his coin that has made this deeps. And the price is now below $4000, now at $3736 with a change of -14.17%. Also, from another article from same app, that the price will get to $1500 by the end of the year. Now am confused.
