After this post I think that it's natural to give a deeper look in the offers of Biswap.
The first menu item that you can see is "Trade":

Then you can choose between Exchange and Liquidity.
By the way you'll use Exchange for swap tokens. There are around 100 tokens, the most common in BSC network.
Now, I set a fake swap, only to evaluate the fees:

Setting a swap of 100 BNB, the fee is around 0,1% AND you'll get a free return in BSW AND a quote of Robi Boost, that is a token used on an NFT game on Biswap.
After all the considerations you want to produce, the real fee is around a 0.03/0,01%. Not bad for a DEX. Usually on a DEX fees are around 0,2/0,3%.
Liquidity, is the instrument to buy LP token to stake or pool earnings.

It works in the same way as PancakeSwap. You got to provide a balanced amount of the two tokens. I found it a little frustrating and I would love a sort of "autoswap" as in Beefy.
By the way, Transaction is the record of your operations.
I'll write about the Earn menu in an another post, in the meantime this is my referral, if you want to give a look, after you made your research.
