Yes. If the price rises too fast like it did in 2013, the price will also drop very fast and have 3 years of price drop.
That is the reason why I do not like big pump and dump. Slow but steady bitcoin price rise is preferred.
In the future, when the bitcoin becomes more mature and price is higher, it is going to be more stable.
Apart from the Bitfinex hack caused price dump, the bitcoin price has been quite stable in the last two months.
I think the current price is quite good to buy. The bitcoin price will rise soon after people forget about the hack.
As long as there is no problem associated with the bitcoin itself, more and more business will use the bitcoin.
