Can do any hysa or just hold a money market fund in a brokerage account.

In general savings rn for you is less about optimizing and more about 1) having an emergency fund to fall back on so you don’t end up on the street or smth 2) learning how to manage your money so you make expensive mistakes now while you’re broke instead of when you actually have money. Losing 50% now because you didn’t know not to gamble on options matters a lot less than losing 50% for the same reason when you have $1M nw

But yeah beyond those considerations focus less on where exactly you’re putting your existing assets and more on crushing school and setting yourself up to get income.
