We've had historically low-interest rates since 2008 because of the market crash. Bitcoin's rise was in this era. Bitcoin promised deflation – that your money won't just inflate away in a low-interest environment.

So what happens if the next 15 years are back closer to the historical average interest rate? From 1977 – 1992, which is 15 years, interest rates were elevated to fight inflation.

Could this be the start of a prolonged period of high-interest rates? What will happen to crypto?
