If your time horizon is long enough, volatility shouldn't matter. Historically speaking Bitcoin is getting less volatile with every market cycle. I would not be surprised if in the future its volatility is comparable to the S&P500.
Why would any sane person invest in real estate? You have maintenance costs, property taxes, it's not liquid and you can go years with little growth. Not to mention if your area see's hard economic times (i.e. Detroit), the chance of a rebound is slim.
You also ignore the premise being put forth, that Bitcoin as a currency still isn't ideal. You don't think "long term investment" with currency so much as short to medium term. Like, will bread and milk cost 10x as much next week?
"Stop thinking investment and start thinking survival" might be a good way to put it.
