What are the advantages and disadvantages of having your private pool?

Currency: MONERO

Currently I have a fully functional pool, configured at 0.1% fee and minimum payments from 0.1xmr, lowering the developer donation to 1.0% to 0.5% and thus obtaining the maximum profit for the hashes generated.

Could you tell me what would be the advantages and disadvantages of having your private pool? and in the case that the advantages are satisfactory, they would like to enter my pool. So we would all support each other.

Thank you!
