Is it better to stake or provide liquidity?

Could you please elaborate on the advantages and disadvantages of staking versus providing liquidity in the realm of cryptocurrency? I'm particularly interested in understanding the potential returns, risks involved, and the impact on overall portfolio diversification. Additionally, could you compare the two strategies in terms of their ease of execution and the level of expertise required? I'm looking for guidance on which approach might be more suitable for a beginner investor like myself. Thank you for your insights.
