What is going on with BNB?

It is just similar to BTC, and many more cryptocurrencies I think.

Finishing wave 5 from b in wave B. So naturally we can wait for a better position to buy (in wave C).

I also should say I guess this is a Zigzag correction.

Stop- loss around 400, incase price goes up.
Expect to find a good purchase point between Fibonacci extension levels .886 and 1 (between 265 and 210 USD). But we should monitor the situation like always.

Please let me know what do you think about BNB
