Speed up more than a 100% gain per year? Nah, especially not for Bitcoin. It's already pushing extreme limits in every direction. Maybe other stuff will surpass Bitcoin, but we'll have to just wait and see.

At x2 per year Bitcoin would be $20M a coin in ten years. With 20M coins in circulation, that's a market cap of $400T, meaning it's already gobbled up the vast majority of the legacy economy in just 10 years.
