I recently became a regular user of the "convert limit" feature since it allows me to keep open orders at specific prices without any fees. Binance isn't obligated to guarantee a price, and the capital set aside for conversion goes into earn simple, so we rack up some yield while we wait for the order to execute.
Specifically, I've used it to buy $PAXG every time it dips below 4480 USD. And today, I managed to scoop up $BTC at 72k and 71k to lower my old average, which was above 86k.
