What crypto would you invest your last $20 in?

I have $20 left after my first foray into the crypto world, getting burned by Shib along the way (only lost around $10 thankfully). Unfortunately I don't have the funds to drop any real money into the market for the next couple of months.

So my question is, where would you put your last $20 so that you could keep going long enough to learn more about crypto until you could afford to put more money in?

I'm not looking to hit it big (impossible with such a low amount I know), I just want to keep this $20 alive so that I can continue learning before I put real money into this strange, new to me world.

And yes, I know no one knows shit about fuck, but I'm trying to learn as much as I can any way I can.
