I would looking into staking stablecoins as a starting point. Stablecoins are assets that are typically pegged to some other currency or commodity. For example USDC is a token which matches the US dollar 1:1. There are many reliable places in the crypto space which pay a high APY, much better than leaving that money in a bank account in my opinion.
If you need to stake stable coins, why would you need to jump into crypto. You can deposit your fiat in the bank and get interest on it on monthly/quarterly basis (although the interest given by banks are less as compare to the APY for stable coins)
A better option is to join the crypto trading where you can trade the volatility and generate much more income.
