Do you know the safest way to stake stablecoins without breaking the bank? Also, do you think it's worth it? Or should I consider other options? Any suggestions and/or recommendations would be greatly appreciated. Thanks in advance.

You could stake on centralised exchange like Binance, Bybit, OKX etc, the only problem with doing that is the low APR but at least you are sure that your fund is safe. I would probably prefer looking for more options with better returns and lower risk.
