Zero maker fees on bStocks run until August 31. That reads as cheaper trading. There is a less obvious reading.

Mechanism. On August 5, with ten new pairs, Binance switched on Spot Algo Trading Bot. A grid bot works through limit orders, so it sits on the maker side nearly always. While the promo lasts, those orders fill free.

What that gives you. The underlying stock trades about six and a half hours a day. A bStock never stops. Most of the day the price moves in a thin market with no reference print from Nasdaq. That is working conditions for a grid: it does not guess direction, it harvests range.

What you pay for it. Three things.

Thin liquidity outside the US session widens the spread. What you save on fees can go into slippage.

A gap at the US open pushes the grid outside its range. The bot has no view on earnings or macro.

From September 1 the standard fee returns. Arithmetic that worked in August may not work in September.

I have not run a grid on a bStocks pair, only watched the ASMLB book: in the European session the spread held around a third of a percent. Before starting I would check that the grid step covers that spread.
