Yeah of cause you cannot compare mining with staking because mining costs way more to set up and pays more but staking is more of HODLing the crypto assets that you have in other to get some passive income from them instead of just HODL them in your wallet. Staking is not as Profitable as mining but you still good for holding stakable coins/tokens.
Staking allows to earn passive income and does not require electricity. So it safe for nature.
For those people why do not want to buy coins for staking they can participate in airdrop like this
