What “traditional banking” stuff can you do on DeFi other than taking high-interest loans in scam-coins like USDT secured against your Bitcoin or Ethereum? How do you take a mortgage loan on DeFi to buy a house if you have a high enough income but little savings? How do you take a business loan secured against my house? You can’t.

You can only do things on DeFi if you have enough BTC or ETH as a security or you can participate in one of the countless ponzi schemes disguised as lotteries, passive income platforms, etc.

You can’t really get “credit” or unsecured loans against you name on DeFi because it’s all anonymous. Don’t worry banks, you’re safe.
