Please see the chart of binance in SPOT and futures.
On closely seeing it, in spot the left wick is lower and while the recent right wick in upper which shows that bitcoin is bullish.
Many traders including me know that btc is bullish, so we placed the stop loss in futures trading just below the left wick.

But look what binance did in futures, they made the right wick lower than the left wick, only to hunt the stop losses of millions of traders.

They are scammers
