Hello, is there anywhere in the BscScan token contract address page an information about the slippage/transaction tax this token requires to buy or sell it?

I am interested in this, because I trade on PancakeSwap using Trust Wallet, but before I buy a coin, I want to know how much slippage % is required for the transaction to pass.

So far, the only way to find the transaction tax % is to check the website of the particular coin, but not all coins disclose this information on their website, so this method is not always practical.

There are hacks circulating on the internet showing how to avoid high % slippage, but from my personal experience they all do not work - I tested them all but eventually I end up being forced to swap with the minimum slippage % a particular coin requires, let's say 15%.

My explanation for being unable to use lower slippage is because the tax % is specified within the code of the coin and you cannot bypass the required minimum %, so this must be specified somewhere in the source code, but I am not able to find it.
