Is this a risk for bitcoin? - Could there be a bitcoin civil war coming, especially about the blocksize or block subsidy? Will the 21 million supply cap ever change? What circumstances would make people consider it? - Threats to bitcoin: privacy is lagging - Things to be excited about: lightning network (near-instant, near-free, more private, and eventually-infinitely-scalable transactions) References https://lightning.readthedocs.io https://github.com/ElementsProject/lightning
