Honestly, I still remain optimistic about BNB in the future. Until now Binance is still the best exchange, and it may only be a matter of time until everything returns to normal. I also think it's a good idea to buy BNB little by little, especially when the price is dumping like it is right now. Sooner or later, I'm sure the price movement will return to normal.
For me, BNB is my third coin in my portfolio besides BTC and ETH. Because for me these three coins both have a good future for making profits. Apart from Binance being the best exchange as you said, Binance has also gone through many challenges recently and they have managed to survive this far, this means that the team they have is also very strong, as long as Binance is still surviving, I will continue to use the DCA strategy for BNB.
because for me it's still worth it, just hold on to the BNB coin and be patient. Later the price will also be high, like the Ethereum coin, the price will go up a little, now while it's still cheap, don't regret it if the price is already high.
