I'm pretty much new in here but I think of the price and market of bitcoin quite similar with the forex. To be honest, I personally think bitcoin is really an additional currency in today's time, a digital currency. And like any currency, its value is fluctuating due to many different reasons. But I believe there are two major reasons for this fluctuation. (1) First is the integrity of the bitcoin and how the people see it. This includes the factor that some are banning bitcoin and has a very negative perspective about it. Although, one thing that people may consider here is that, the riskier the investment or currency is, the greater the possible reward. Another (2) is that, Bitcoin is also affected by the law of supply and demand, which can make the price of bitcoin drop so much or make it skyrocket. This may sound very generic but this is my honest opinion at this point in time.
