Every investment carries risks, even storing assets like tether. But Aave has proven itself as a strong platform over time. If Aave were to fail, it would signal a problem not just with it, but with crypto in general.
Think about the impact on the crypto market if a big player like Aave were to crash.
Now, imagine someone who puts 50% of their savings into USDT, planning not to spend it. For example, if they have $500,000 locked in USDT, they could earn $50,000 annually without doing anything, as long as the︀ APY remains stable.
In my opinion, life teaches us that nothing is completely secure. Just︁ look at how Silicon Valley Bank crashed less than a year ago. But when it︂ comes to investing, I don't think Aave is much riskier than the top 10 to︃ 50 US banks. These banks typically don't offer returns as high as 4-5% per year,︄ and they haven't proven to be better than Aave at this moment, just a smaller︅ APY
The other option is keeping the stablecoin in a cold wallet, but there's no︆ benefit to that.
