So even bitcoiners admit that it doesn't work as a currency because it's too difficult for people to trade in and out of regular fiat and storing them properly is too complex and dangerous.
So the answer is... open an ETF to allow computer illiterate people the chance to "invest" in a currency that is too complicated for them to use in the first place. Brilliant!
Today, it is too hard to store and use. Hardware wallets will change that. Today, it is too hard to obtain. That's gradually changing, too. But if you wait until the infrastructure is fully in place, you miss the run up.
Who struck it rich by investing in Google? Those who saw the promise from the beginning, or those who waited until it was fully functioning? The rewards go to those who can see the potential of great new ideas early on!
