The risks of staking.

Slashing hits validators that sign conflicting messages — for example two blocks at the same height. That is almost always a misconfiguration: the same keys live on two machines at once.

Besides a direct penalty there is a forced exit and a correlation penalty that grows when many validators fail together. One isolated mistake is relatively cheap; a large operator failing at scale is expensive.

Being offline does not cause slashing but misses rewards, roughly symmetric to what you would have earned. During extreme network outages an inactivity leak can erode your stake.

Practically: aim for stable power and internet, use automatic restarts, and never test a backup with the same keys active at the same time.

Ethereum has activation and exit queues that grow when busy. Cosmos chains often apply a fixed unbonding period of several weeks. Assume your stake is not liquid the same day.

If you might need liquidity, do not stake 100 percent of a position.

In practice, holders lost far more money in recent years to failing platforms promising yields than to slashing. Any offer with a fixed high return in a volatile market deserves suspicion.
