From what I've heard about bitcoin, as well as currency values, such as Dollar / USD, Bitcoin prices are fluctuating or up and down. Importantly, the price of Bitcoin is more fluctuating than the fluctuation of the US Dollar. Thus, if we want to buy Bitcoin, it is important to understand what things can cause the rise and fall of Bitcoin prices. If we want to invest Bitcoin, it is also important to understand these things. By understanding these things, we can buy Bitcoin at a low price. And also, can sell Bitcoin with high price. And the factors that influence the rise and fall of bitcoin prices that I know are.

1. Bitcoin Security Factor
related security factors, in the year 2014 ago, there was a massive robbery in one of the Bitcoin buying and selling place in Asia. The event made the world's public doubt the security of Bitcoin. If the world's public doubts the security of Bitcoin, Bitcoin's demand will decline. The decrease in Bitcoin demand will be followed by the decline in Bitcoin prices.

2. Community Perception Factor
Perceptive factors also affect the price of Bitcoin. If Bitcoin gets a better perception, Bitcoin's demand will increase. Followed by the increasing price of Bitcoin. Conversely, if Bitcoin get a bad perception, Bitcoin prices will go down. These perceptions include how perceptions of the ease of using Bitcoin, the perception of how future Bitcoin prices are and the perception of how much profit Bitcoin invests. For information, several years ago, Bitcoin was so synonymous as a means of exchange for buying illegal goods. Over time, these perceptions begin to disappear.

3. Official Bank Recognition Factor
Some countries do not recognize Bitcoin as a legal means of payment. If the central bank recognizes Bitcoin as a legitimate means of payment, Bitcoin's demand will surely increase. Bitcoin's increased demand is followed by higher Bitcoin prices.

So few things that affect the bitcoin price according to what I know so far, if you have any other reason, what's wrong with explaining it, I'm sorry if there's a mistake, and thank you.
