No, you cannot stake Bitcoin.
Bitcoin is a proof-of-work cryptocurrency, meaning miners are the ones who validate and secure the network (and earn mining rewards for doing so).
Proof-of-stake cryptos, like Ethereum, uses staked funds to validate new transactions and keep the network alive and running (and earn staking rewards for doing so).
So, no, you cannot stake Bitcoin directly. However, you can wrap Bitcoin (wBTC), run it on the Ethereum network and then use different defi protocols to earn yield, but that’s a more advanced discussion for a different day!
Trust no one!
