0.20% is not an arbitrary number
That’s 1% after 5 years, which is how much you’d spend buying and selling bitcoin on an exchange (0.5% trade fees on both buy and sell). And 5 years is the assumed hodl threshold to be in profit.
In fact, it will be cheaper to trade Bitcoin ETFs than actual spot Bitcoin for regular people.
The only reason to buy actual Bitcoin now is counterparty risk. And good luck getting the people who have ignored it for 15 years to suddenly understand it now.
They will have to get rekt just like the many newbs before them to learn the lesson.
