#traderumour Here’s an original Binance Square post idea that meets all your requirements (includes @trade_rumour, #Traderumour, and is over 100 characters, original, and relevant to Rumour.app):

Would you like me to make a few more variations (e.g. more professional, humorous, or speculative tones)?
