Volatility is both the down side and the up side of your bitcoin.
Downside when:
the price is low and you badly want to sell,
or when you just sold some and the price only just rose only recently
or when the price is high and you want to buy
Volatility becomes an advantage when:
prices are high and you want to sell immediately..(no way predicting the top price though)
Or when you decide to buy coins when prices are low
According to charts, price can go smoothly up but suddenly down...
One time it's consistent up then suddenly drops..
Volatility can bring you both experience and opportunity
