Three jobs, not a ticker list

A friend describes their holdings as "mostly stable growth". What is wrong with that label?

• Nothing, as long as the coins are well known
• It blends two jobs into a nickname, so you can't tell which risk is which
• Stable growth is a fourth job the course forgot

USDC in your wallet and USDC supplied to a lending market share a ticker. Why are they different lines?

• One can be spent now; the other depends on the lending market letting you withdraw, and is paid for that risk
• They aren't different; the ticker decides the job
• The lent one is beta because its rate moves
