Factors that influence the value of the bitcoin:
1) government bitcoin policies and laws
2) political situation
3) social trends
4) appearance of new competitors
5) artificial influence on the value by trading at the crypto market
6) news (not always true one)
and many more. Could be something new will appear in the future. Did I miss anything?
Yes, I agree. All will form FUDs to threaten the value and psychology of investors. We can see the past is a panic from the market. One of them is the hacker problem from a Korean coinrail trading platform. It is spreading a tendency to drop prices very fast. It is a fact that the crypto market this year is very sensitive and easily melted. But it does not last long.
