I borrowed against my crypto for USD/USDC and used it to buy a MacBook and pay my tuition. The underlying coins appreciated and earned interest in addition to negative APR (this is all programmatic; the contract will give the best interest rate the market supports) on the loan itself, so I ended up paying back less than I put in.
Keep in mind: I am not in any way rich and paying out of pocket or taking a loan would have strained both me and my parents.
