Price fluctuation on bitcoin is normal due to its changibg supply and demand. Usually increase in supply due to panic selling causes its price to decrease. But thats normal. Dont be upset. Its price will still rise. Just be patient. And play on its price wisely.
For me, there are 2 reasons why bitcoin price is increasing and decreasing; 1st is its because of its volatility, means that the price of bitcoin is changing rapidly and its unpredictable to know if its going to increase or decrease, and its normal; and yes 2nd is because of supply and demand. We cant stop people from panicking, i suggest that let them be, for them to know what is bitcoin, and what bitcoin can do, for them to know what is the right to do when the price of bitcoin drops again.
