@OP, what else is a (good) hedge against inflation in your opinion? What has performed better over the last 5+ years? What has preserved your purchasing power better? Gold is maybe the second best and it doesn't come even close to BTC in performance & attributes as money / capital.

Volatility is only a problem if you have a short time horizon. Save for at least 5 years (better yet 10+ or 15+) and volatility becomes irrelevant. Also every asset worth trading is somehow volatile.

Bitcoin has better characteristics (as capital) than gold & real estate. You own it yourself, you can move it easily, no upkeep, no repairs, no expensive security required, border-less, permission-less...
