compare to solo staking the pool is quite easy as in solo staking firstly u should have minimum coins to stake ,u must have a high-end system ,there should be 24/7 current supply ,24/7 ur wallet must be kept on which is quite risky but in pool no need not have minimum coins to stake and no current supply and even u need not keep ur wallet on every time ,even if ur wallet is off the coins will be staking
