What bitcoin do with the people.

The bitcoin price is struggling from the last year. Last year the price is reached about 20000$ but the current price is 5,584$. That is a huge difference in the price of bitcoin. Why bitcoin reached this place because when a bitcoin holder start selling bitcoin of a huge amount then suddenly bitcoin price is down because bitcoin holders start stocking the bitcoin and hold it till the price reached to its maximum worth and then sale and earn a huge profit etc.
So if any correction is required in this knowledge then comment below so I learn more due to your comments.
Thank you and predict how much go up bitcoin in this month.
