As subject goes, is Bitcoin the maximum version?
Is it still possible to develop it?
or
Can we still expect better coin than Bitcoin?
In my own opinion, bitcoin is still possible to develop since we are in the modern age or technological age. Since, technology innovates the bitcoin and other cryptocurrency is not necessarily needs to keep up to the technology. But I think, the only thing that we need to expect the most is its price in the market or for its better trade to other cryptos.
