HOW LIKELY IS IT THAT BITCOIN BECOMES OBSOLETE?
No industry likes being disrupted...especially a $20 trillion industry. Bitcoin has the largest network effect so in the event of a contentious hardfork how likely is it that Bitcoin becomes obsolete as the main currency and other currencies take over? How likely is it that bitcoin will become obsolete?
There is a big chance imo
Forking attacks are totally real---but it will become battle tested and that adds value long term.
