Binance is not in any way acting to protect investors confidence in the Bitcoin market, but rather binance taking advantage of the recent Bitcoin price dip to bag up more Bitcoin to their portfolio, this is what most big cryptocurrency companies with large liqudities in stable coins so each time of the bear market, they always buy the dip and wait.
They are cleverly exploiting the situation. On the one hand, they are supporting investments in bitcoin by buying at the dip, taking advantage of the market decline regardless of all other reasons. On the other hand, they are using this to market themselves as loyal company to their investor but also to bitcoin philosophy. I can admit that this is a clever action from binance as it was able to do the mission behind scenes. Now see the advantage for this to its reputation.
