Utilizing your own liquidity pool for sniping has some benefits such as: 1) The fact that it prevents outsiders from sniping the supply of your token, 2) It is possible to have a price floor in place which protects against drastic price drops, 3) Stability can be guaranteed in the price which is important for assuring investors, and 4) It helps your token to gain traction around the numerous websites since the initial pump tends to attract bots and possible investors.
