But maybe there's still some folks out there that prefer paying a management fee over learning how to secure the coins themselves
I can imagine it "feels" safer and especially more familiar to see a number no your screen in your broker's account, than having to deal with your own transactions. People are used to buying ETFs this way.
But the management fee is a good one: I
hate those! I wish I could just keep my own shares and store them by myself, instead of paying my broker
and the fund owner.
