What’s the best way to generate income from ETH holdings?

Say you had $10k/25k/50k in ETH. Which is the better strategy to generate income?

-Staking on an exchange or ledger

-Converting funds into an ETF and selling calls

I know that the latter depends a lot on the specifics of the calls sold and carries the risk of closing out the position.

But I don’t know how to calculate the potential return of each strategy vs the risk of a big upside move, or how the total amount of the investment might change the calculation.

If anyone has any insight into this or better advice in general, I would love to hear it.
