I don't know what staking is, but I invested in Ethereum 20 days ago and have gained 30% profit already.
Staking is when you lock your tokens and in return receive more of them.
Ethereum is moving to staking as its main way of producing more ether as of the London Upgrade (EIP 1559), scheduled for July. Ethereans are pretty excited about this, and the details of the EIP 1559 mean that it is likely that eth will grow ever more scarce (so people are calling it "ultra sound money", compared to bitcoins "sound money".
A lot of staking solutions have no actual purpose but ethereum is different, as the staking secures the network through staked validators who check the transactions and keep the network honest. If they behave badly and pass through faulty transactions or are lazy and dont keep validating the transaction, their staked ethereum is "slashed" (ie the ethereum protocol takes some of their eth as punishment), if they behave well tho, they are rewarded with approx 20% extra eth per year.
It costs a lot to run a full eth validator node (32 eth, approx £100k at the current exchange rate). However there are various solutions for smaller holders to also stake.
Centralised exchanges like Coinbase and Binance will stake the eth in their vaults and pass on some of the rewards to people who have eth in their system, but thats likely to be pretty small.
Decentralised solutions exist, the best known is probably RocketPool, (www.rocketpool.net/) where you can run a validator node with just 16 eth rather than 32 and other people can make up the difference, and also receive staking rewards.
