I don't have enough for bitcoin miner fees. What should I do?

Should I wait for Bitcoin miner fee levels to adjust downward?

or use a lower than recommended Bitcoin miner fee?

I mostly get my bounty rewards in BSC coins but this time I got in BTC and the fees are pretty high.
I did some research and found out that I can move my btc private key to another wallet, But I don't know if it's safe or not, I can use this and wait for my other btc payments and then move.
Please share your recommendation, thank you
