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.
Seems a bit that is what happen to his order or he even said Bid someone had definitely bought your currency bid and has more money than you, I never expected Binance to do such things because I am using that site for trading, And buying newly added coin and I don't have any problem using their services and also bought Binance Coins to be added to my portfolio lists, And OP doesn't have enough proof or what so ever regarding his issue.
