#SaylorBTCPurchase $BTC

Could you please clarify your request a bit? It seems like you're asking for an article involving Binance, BTC (Bitcoin), "Koi nani" (which might be a name or phrase in another language), and BNB (Binance Coin).

Here are a few interpretations:

1. Do you want an article *comparing* BTC and BNB on Binance?

2. Are you asking *what role* BTC and BNB play on Binance?$BNB

3. Is "Koi nani" a person or brand to include in the article?

4. Is the article supposed to be in English or another language (like Hindi or Urdu)?

Please confirm the goal and language, and I’ll write it accordingly.
