Bitcoin attracts most users only because of its rapid price increase, and its stability will lead to a decrease in interest.
I agree, because most are traders or hodlers at the moment. They would all go into Alts or another form of investment if there was a prolonged period of stability.
Price Stability means there is a stable demand for Bitcoin, but it does not mean there is or will be an decrease in interest because not everyone is a trader but is also using Bitcoin as an actual currency. A stabler pruce will lead to an increase in Bitcoin transaction as a currency.
