I made a research as to inform myself as well how these prices are affected and I would like to share some.Here it is, the factors that influence the price of bitcoins are quite diverse. Some of them are slow but quite steady, such as the gradually rising supply and demand curve. Others are sentimental and violent, like the speculative trade, which influences the trading of bitcoins each day. In spite of the opposing forces, which often exert their influence on the bitcoin market, the long-term average price seems to be on the rise. Note that learning about these factors will not necessarily make the bitcoin price more predictable. However, understanding them can help you to be more comfortable with the price fluctuations and make informed decisions at the right time.
So, there are many factors that affect especially in terms of which affect the amount of supply and demand. Another factor that is quite influential is the rumour spread in the media, both positive and negative news, and the issue of legality.
