I tried it once, putting ETH into LST for restaking, at that time I didn't even know the difference between stETH and rETH, but I just clicked because the APY number looked nice.

Where does the yield come from? Simply put, you stake your coins to a node, the node verifies the network, and shares some interest with you. Restaking is adding another layer on top, staking to other protocols for extra points or airdrop expectations. It sounds like Russian nesting dolls, and indeed it is.

As for risks, I don't think it's smart contract hacking—although that's also scary—what's more annoying is liquidity being locked up, or the underlying asset de-pegging. Last time there was a small LST project with a shallow pool, when I wanted to exit, the slippage directly ate up two weeks' worth of gains. Forget it, let it be for now.

Lately I keep seeing Meme coins rising again, celebrity shilling is like a relay race. Someone in the group advises newcomers not to catch the last baton, but honestly, I can't tell which baton is the last one myself. Anyway, the speed of attention rotation is faster than I change wallets.
