Inflation of 2.3% over the next several years compared with the extreme volatility of bitcoin isn't even a question.  The dollar wins hands down.  Your bitcoin could be worth $40,000 next month or $20,000.  That's not protection from inflation.  To actually protect against inflation, you need something that holds a steady and predictable value.  Not that I think people shouldn't own bitcoin, but they definitely need to not delude themselves into thinking they're protecting themselves from what is ultimately still a low inflation rate by doing so.
