I checked the Bitcoin price and did not find a decrease. What is happening is a natural price movement, perhaps due to panic or panic, but the price is in its normal place.
The value of BNB decreased by more than 22%, which is a large percentage, but its price is in the hands of binance, they can burn a lot of it and the price will return again. the reaction of binance and the subsequent steps that it will take are what will determine the future of this currency.
I advise you to stay away from it for the time being and see how the company will act.
