Yesterday at night I made the bid purchase offers on Binance. When I woke up this morning, I claimed that my offer had not been made.Is Binance cheating?As you can see, my offer is set at 237 satoshi
The chart shows that the coin fell on 236 satoshi.
Why has my offer not been completed?
I'd say what happened was that someone went to sell into your buy order and had more coins than what you were buying. So they clicked on the order right below yours. Usually exchanges will still sell your order first though. Binance may not. I haven't used it all that much. But, this seems like the most logical explanation.
