Bitcoin was indeed stable and that is bad for the most people with already Bitcoin because they want to earn some profit with Bitcoin and that was not possible so they have to wait now a longer time until the can make profit.
But of course it is hard to know when you can sell it but you also can see now that the value of the Bitcoin is rising slowly so that is really nice for the people with already Bitcoin.
The problem is now the price is rising too fast. It would be better if the price consolidate here for a few months.
It has always been the case with Bitcoin. Sometimes in the past you would have been surprised by how long the price can rise at such a pace. This time is/can be no different.
