The chart is really self explanatory. The more lines closer the more resistance.
We can see support really built up from 18348 to 19483. I see this as a safe area to pick up BNB for at least a good bounce up.
21762 seems nice, but with the 50 day and 20 day ma about to cross down, Id be a bit worried about taking a trade there. Assuming i wanted to have a nice low risk high reward trade.
20282-20653 seems to be the better spot for BNB to want to stop before it tests back upwards.
The problem with after 18918 and 18438, is that there is a large possibly of the trading view now being looked at from the next trend. So it would look more likely for it to bounce again around 17146-17451 to around 18918.
There isn't much more to say. Everything is pretty self explanatory.
Disclaimer: I don't believe in hodling so I would never buy anything to hold more than it looks like its worth. AKA a defined start and stop.
