Bitcoin and altcoint fluctuate where market prices go up and down at any time, but you can prevent price reductions by holding prices down! Do not get involved in the wrong problem and make you sell below your purchase price and obviously hurt yourself and the other coin owner ,, keep enduring and the price is definitely going up !!
Many bitcoin holders are doing panic selling when bitcoin experiences crash or when its price is going down. Instead of just holding their bitcoin, they just sell it even with a low price and they will lose a lot of money that they invest in bitcoin. Those people are not patient and will not experience being successful in the future.
