Volatility isn't good unless you sell the peaks and buy the dips. BTC is young and it's going to be volatile for years to come.
Yes thats true , if Bitxoin is not a volatile currency we should be all worry about it and I think it will not be famous as now it remain as cheap like before, cause Bitxoin became popular because of its price nowadays.
Yeah indeed having something saved is just a blessing and for sure it will give me and you more profit in future. Well as for being decentralized currency, volatility of bitcoin is main feature of bitcoin. on the other side it is bad because some countries are not trusting bitcoin because of changing price each month. It is good for those who are investing because when price of bitcoin use to change it goes high and bigger in price.
