You did not do enough research on Bitcoin that is Proof of Work, not Proof of Stake.

So initially by technical design, bitcoin is not for staking. You can only get bitcoin from Proof of Work mining and Bitcoin block rewards as well as Bitcoin transaction fees. Otherwise, you must do things beyond Bitcoin blockchain for staking rewards but it is risky.

You need to convert your bitcoin to Bitcoin Wrapped tokens that are not bitcoins. Those tokens are altcoins and peg to Bitcoin price, though those tokens can be depegged. Staking pools can be scam and you will lose your bitcoin in many ways by staking.
