I agree in retirement accounts it’s a good play but there is rug risk and if/when the dollar collapses, that retirement account will pay you out in worthless fiat. But since the government and stock broker can turn off the buy button, then it’s not much of a stock. Before people used to trade stock certificates physically. Now they’re all held/managed digitally by the DTCC. There are rumors that there are more stocks in circulation than stocks that can actually be redeemed so there are some stock printing shenanigans going on. Self custody Bitcoin is king. 

 TLDR except the final sentence which is 100000000% accurate.
