Scalability matters to a currency that has ambitions to become a global payment system, but the inbuilt limits in the Bitcoin concept show that it was designed to prevent this from happening. Bitcoin is making a transition into a long term store of wealth, and this means that security, and possibly confidentiality, are of greater importance. It also means that more sophisticated transfer controls will become important. SegWit and other developments are helping this.
Should we accept that Bitcoin is now a store of wealth, and that scalability is no longer a major focus for the future?
