If you wanted to bet on Bitcoin from your grownup brokerage account, you already have a plethora of options:
- $GBTC and $MSTR are piles of bitcoins with a ticker wrapped around it.
- $MARA, $RIOT, $BTBT are bitcoin miners, which basically track the price (with some leverage ratio >1 )
- $COIN is effectively a large cap ticker following the crypto market cap (with some idiosyncratic risk)
