There are very few projects in the crypto world that truly achieve decentralization.

Because most projects have administrator privileges.
They can directly operate on tokens or vaults.
And they do not disclose these actions.
At the same time, the crypto industry lacks regulation and constraints.
When something goes wrong, the project team can completely avoid responsibility.
So it's best to only participate in these projects when the market is good and there are high returns.
After that, just stop.
Losing your principal for less than 10% profit is not worth it.
I took a quick look at AAVE, and there are a bunch of assets with unknown prefixes.
All of these are put in one basket.
It's not surprising if something goes wrong.
Other lending platforms are even more so.
In summary, the DeFi industry is very difficult to compete with traditional finance.
If there are no fundamental changes in the industry, there is little room for development.
Cases of theft will likely continue to happen.
