There's no way in hell you could convince me to invest in anything as volatile as a pile of crypto coin for my retirement. My retirement account is for slow, gentle, growth, not for a rollercoaster that could end up at zero (within the realm of reasonability - yes, the entire stock market could disappear, but at that point we're not retiring, we're firing up the pursuit special and heading into the desert). This is why ETFs are so popular - they remove a lot of the volatility.
Why would I put my money under the mattress if I could pull it out tomorrow and it'd be worth half of what I thought it was? Yes, inflation is a thing for fiat, but that's nowhere near as volatile as crypto has and continues to be.
