Evidence suggests it's the exact opposite. The only thing crypto has really been good for is a store of value. Sure, it's a volatile commodity, but over any 5 year average window, Bitcoin definitely beats inflation. That makes it a safe store of value.
Huh. While I agree that Bitcoin specifically has been a successful speculative investment in the past, "a safe store of value" is a massive stretch. It's a safe store of value in the same way a S&P 500 index fund is, except more volatile. What's that phrase... "Past performance is not indicative of future gains?"
