I am confused??? whether people are not aware that bitcoin prices are designed to fluctuate. I do not think it's weird if the price keeps going up and down. actually the price can go up if a lot of people are buying and even vice versa too, if a lot of people who sell it the price is sure to go down, ordinary its cause the people who sell the coins is due to panic or a lot of negative news that are constantly insistently hit the coins they held and not a few FUD also spread.
we also as users should know that the small bitcoin volume scattered in the network, so do not be strange with the arguments of people who discuss the issue of rising and falling prices.
