Bitcoin will probably not have to work much because FIAT currency is going to fail in droves in the next few years as the CENTRAL BANKING policy of MOAR stimulus will unleash insane inflation. FIAT has destined itself to the fate of all others before it. 100% of fiat currencies fail because they simply cannot control themselves and print to oblivion. That is where we are at today.
The result? People are already flocking to Bitcoin. Every single time there is a disaster of some sort, people are moving to Bitcoin. Brexit? No problem... buy Bitcoin. Korea launches a missle? Buy Bitcoin. Trump becomes president? Buy Bitcoin. Faith is being lost. If you can't see it then you might want to make sure you are not a frog in a pot of boiling water because it's getting awful hot.
Bitcoin is an emerging technology. It's going to change how the world works. Given that 4% own 95% of all Bitcoin... not necessarily for the better. Given that the sixth mass extinction is already underway, there are no guarantees we'll even be around to witness it.
One thing is certain: Central Banking policies of endless QE are doomed to failure and fiat currency will end as we know it. The social unrest, the wealth inequality, the inflation in the markets, and the migration to Bitcoin prove that it's already happening.
