What Staking Pays
Staking looks like easy money, but as a validator, you are doing protocol work, with rules, penalties, and non-compounding sweated-out rewards.

Where the Reward Comes From
Rewards in Ethereum's proof-of-stake model come in the form of newly issued coins plus a share of transaction fees collected that split among validators. An economics paper explains that they are remedying the problem posed by: that you can't create the majority of the supply until long after people enjoy free money. They describe rewards as meals: valuable enough to marshal, but not so potent as to incentivize abuse.
Who Can Participate, and How
To be a validator, an operator needs a minimum of 32 ETH to be able to run their own validator node. Smaller participants can join staking pools or service companies that split the rewards, and take a cut, fees vary by service, so a medium-size holder joining a staking service would want to compare cuts (plus risks) to balances deposited.
What the Headline Yield Leaves Out
Participants might not be on inflammatory talk of returns and inflation arbitrage, afforded as defense. "It's guaranteed" say coaches to the unwary. But it's not a bank. Validators online too often will have slash deductions and may be forcibly removed. Slashing penalties will weigh down the net yield, not to mention if the coin itself falls in value. On top of that, some reward balances have a lockup period (while awaiting changes to the protocol).
Why Withdrawals Matter
Apparently compounding rewards are a misunderstanding. For compulsory withdrawal types of Ethereum validators, once rewards above 32 ETH kick in, any rewards above 32 ETH are automatically transferred to the validator's cryptographic withdrawal address within a couple of days; 32 ETH validates, 2048 ETH is the maximum effective balance. If staked in a broader staking service, then the rewards policy can offer an 0x02 mode that lets those be combined programmatically, but then again the operational risk increases.
The Service Layer
It would be mundane to treat all services as equal; And registering is holding a service company responsible for operation, with some (but not all) asking for custody.
Services for Servicing
The differences between Ethereum services depend on whether you need a compounding credential type, varying in fees and lockup periods, with various lockup periods afterwards.
Close on Risk, Not Rate
Ethereum staking eats incentives among competitor cryptocurrencies, in a seemingly-profitable paradox. But from the perspective of what you get - net of compounding, slashing, withdrawal limits, market downturns, and untrusted service execution versus your own computational and custody challenges - most stakes are not so straightforward.
