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.
The bitcoin market cap is just $10 billion at the moment, it is smaller than most companies, it is easy to manipulate.
