BNB is overbought. You can see not just in 4H time frame, but in 1D, 1Week, 1Month.
Do you think it will going more higher? I don't think so.
I know Binance is the biggest exchange in the world, also have great fundamental. But thats not mean BNB must rise every time.
Just my opinion, you can see BNB will go higher more than 450 or no. There's still a chance BNB can go higher than now.
