What are the potential risks of this strategy?

Am new to crypto and read up a lot in the past few weeks.

So just for example, I buy $20,000 worth of ETH, lend it on AAVE, borrow USDC against it and redeposit that into AAVE to get some interest.

Then after a few years value of ETH triples/quadruples and I withdraw and sell some ETH to liquidate my borrowed USDC, I'll be left with more ETH than I initially bought even after deducting the interest on the loan.

Of course if ETH value tanked, I'll be screwed any how. Are there any other risks besides that?

Also, USDC is not supposed to change in value, but if it crashes, more good news for me?

Or is it wise to just buy the ETH, store it a cold wallet and HODL?
