https://charts.bitcoin.comOfcourse bitcoins volatility is normal, thats why investing in it gives a higher risk than a traditional investment but also gives a higher profit. Just do not panic on some of its drops because it will rise soon. Panic selling brings nothing but failure and holding your stocks is a better idea than selling in low price.
