Excuse me, I'm curious about how one can potentially purchase cryptocurrency on Binance without incurring any fees. Could you elaborate on any strategies or methods that might allow for such a transaction to take place? Are there any specific conditions or promotions that I should be aware of in order to avoid paying any fees while trading on the Binance platform? Additionally, is it feasible to maintain a long-term account on Binance and continue to enjoy fee-free trading, or are there limitations to this practice? I'd appreciate any insights you can provide on this matter.
