Can anyone tell me about the causes which make Bitcoin price rise or fall?
Can we guess when it will be the best time to buy or sell it? Can it be forecasted?
Too fast rise, profit taking, inspection of chinese exchanges, some FUD, overreacting market and so on and so on.
There is not one specific reason.
And yes I would see this now as a time to buy.Of course the price could drop further the next days who knows.However if you should be in Bitcoin for the long haul, meaning mucgh more years, it won't matter that much imo.
