We must get this volatility under control.
We are.
Volatility is decreasing since day one (infinite volatility from zero to 0.01 cent).
You can't expect it to be a sudden flatliner one day.
We will reach a flat line when the market cap is representing it's true value, not it future value like now.
Right now we are speculating on the future value of bitcoin, therefor we go so much up and down because we have a hard time predicting what the future value will be.
On the other hand you can find a pretty straight trendline throughout the price untill now.
There will be some pumps and dumps on the way up, but when we get there the ride will become easier.
It also means that there won't be as much profit in the future as you can get right now.
