But the storage and exchange of keys to blocks seems not so secure again and again.
This is the way it is with all security. It's always a tradeoff between keeping unauthorized people out, and allowing authorized people in.
Your house has a key to the front door, but it's relatively trivial for a robber to kick the door in. So do you replace your front door with a heavy bank vault, with multiple locking mechanisms? You won't do this, because then *you* would have a hard time getting in and out. Instead, you make friends with your neighbors so you can look out for each other, you get insurance, and you invite the police to patrol your neighborhood.
Speaking of bank vaults, most safe deposit boxes are inside a vault. But during the day, people need to be able to access their box. As a result, many banks leave the vault door open during the day, closing it only at night. Or at the very least, they have to open it whenever somebody wants to access their box. This creates a security vulnerability that can be, and has been, exploited.
Crypto is no different. There is a balance between security and access. This always leaves vulnerabilities that cannot be "fixed."
Banks solve this by buying insurance, both government-based and private. Binance did this too, but it seems they didn't buy enough. Now, they'll have to buy more, and their premiums are going to go up considerably, making it more expensive for them to continue operating.
It will be interesting to see how long it takes for the next heist. You can be sure another one is coming.
