How to avoid high gas fee for staking?

I usually use L2 for widthrawing/depositing but how about staking fee? Suddenly i have crazy high fees for staking alone.

also currently most of my local cex still offer erc20 network with crazy high gas fee, so when I transfer USDT or ETH is quite crazy, and they don't offer other pair-coin beside top 10 coins.
My friend already bought in shitty cex because it's offer local currency with his bank and stuck with high gas fee with limited options
