Mutual funds are an investment. Hoarding is savings.

One is productive, one isn't. That's the key difference.

The difference is even more glaringly obvious if you think about the difference between equity in a productive company, loans to productive organizations, and simply doing nothing.

Savings accounts have interest rates. The money in savings accounts is used by banks to leverage and invest. It's not really hoarding like holding on to bitcoins is.
