in fact that ups and downs of coins is natural because of demand and also popularity of coins
after the downs of coins BITCOIN to be specific is will grow even bigger and much higher than what you think
bitcoin for me is alternative money and yes for me it will never replace fiat
Yes, but not by such large percentages. the massive movements in a single day make it risky to use as a merchant because you can't set a price for your goods in bitcoin because you simply don't know what you are going to get. Which means merchants are still pricing in dollars, which defeats the whole purpose.
