These are smart contracts that do not have the function of trade tax and transaction tax. And there will always be different amateurs easy money. They will put their bots. On the dex exchange. On contracts where there is no tax. These bots will see you and make transactions and buy or sell faster than you.) Therefore. In settings. Before the deal. On the exchange dex. Don't make it big. Price slippage. Otherwise, your transaction will be completed at an unfavorable price for you.
