For pancake tokens with slippage is it better to use swapExactETHforTokens or swapExactTokensForETHSupportingFeeOnTransferTokens if amountOutMin is equal to 0? In this way I will not get much higher slippage rate than token have ? For example token set slippage 7% and I will be charged 15% ? What is the best function and slippage settings to buy tokens on bsc with slippage? Thank you
