I prefer to see the increase up for Bitcoin, unfortunately it is not on that choices. I am trader even though in small portion or amount, I definitely like to see the volatile of of Bitcoin value than stable. Because I can buy in low price and sell it when the price increase. However, now it is difficult to do that because for recent several months Bitcoin price movement is very slow. It is not a proper time to do short term investment or trading.
Volatility is what I choose even you invest for long term or trading because you can see the market change and profit at the same time. If bitcoin is stable it is just like a gold then that will not give you opportunity to buy in low price but for its stable price and wait much longer time. Stability cannot help for bitcoin to be used even as payment method then.
