I believe people have different explanations as to the reason behind bitcoin fluctuation in value. personally I always deliberate on the forces of demand. because when there is low demand, the value will be low.
Actually the high supply of bitcoin is one of the reasons for the value fluctuation because when there is low demand for bitcoin, the value price will be low and it will be high when there is high demand.That's true, that's the only thing behind the rise and fall of cryptocurrencies, I think we have a high supply of Bitcoin that's why is falling down like brick.
