Liquidity pools are used by on-chain automated market makers like Uniswap (on Ethereum) and PancakeSwap (on Binance Smart Chain -- BSC).

I added my LP on the BSC chain. You can withdraw your BUSD onto the BSC chain, but you'll also need to use BNB as "gas" - it's not quite as simple as using the Binance site.

There may be options to invest directly on Binance, I don't know because I don't use them. I've heard about their launchpool, but do your own research on the risks.
