Oh no. The price went up from around $250 to around $340 in a couple of days. That is a 25% boost in price. The price is still not close/half of the all time high. With the bull run and Ethereum chain already unusable, Official and unofficial BSC tokens are a good way of trading and investing in alts with lower fees.
This could also be a bull trap before the drop around the sentencing of ex Binance CEO CZ. But BNB is already not much dependent on the Binance exchange.
A Bull run is difficult time to make a decision. The day OP asked the question now seems one of the best time to buy it.
OP asked around February 2023 and at that time based on CMC data the price of BNB was around $300 and currently the price is also around $300 and heading towards $400. The lowest price of the year is around October at around $200. So I think if at that time the OP chose to buy it then he would have made a profit, even if it was a little. The best month to buy BNB this year is October and I also saw that BTC also had a price of $28,000 in October and now it is $42,000 towards the end of the year.
