That's a lot of money. I wonder how many platform actually dies due to hack or something similar? If they can keep operating like normal with little to no damage to their earning, I guess that's why stuff like this keeps happening. On the other hand, it means there are tons of money in the defi space still. I'm not sure how many users actually put too much money there. It's hard to discourage them from staking and whatnot if they feel losing $10k is acceptable.
Many of them died after the hack but not the kind of die that you expected such as declaring bankruptcy or other formal way of declaring that they are out of business.
After the hack, the protocols will be dying slowly. Their tvl decreasing to 0, nobody uses the protocol anymore, their coin lose its value and eventually fading slowly.
I don't know why some protocols don't want to declare bankruptcy but I'm guessing that its because the legal consequence that entails and they prefer to keep their protocol slightly alive and keep it in a limbo.
Some that are lucky to get a loan and help like what happened to AAVE with the help of DeFi united initiative will continue to operate but the one that getting the hit without the help usually becoming a dying protocol.
