Bitcoin might be stable and be called cryptocurrency king now. But don't forget that ideas and solutions change very fast in the blink of an eye.
Remember Yahoo? It once was the greatest company of modern Internet and then Google came. With bitcoin could be the same.
Bitcoin is stable now?
Its volatility is as high as ever.
it depend how you look at it, we are always in the same value, and in the same range with the same pump
so by this point of view, i consider it stable, because the price is predictable
