Be careful when brushing BR, Binance will likely intervene; otherwise, it will just get fattened up and become the next ZKJ or KOGE.
I took a look at the $BR pool, it's really crazy, with only a very narrow 0.0478 having liquidity. I can't imagine what would happen if someone just casually pulls or dumps it.
Recently, brushing alpha feels a bit like playing with fire, the AB pool is similar. It's better to brush with small amounts; I'd rather incur a bit of wear and tear, just in case it turns out to be the next ZKJ or KOGE. If you really want to add to the pool, be cautious about hedging!
