According to @EmberCN, Binance is offering a reward of 8 IO tokens (valued at $35) to the first 700 new users who register using a specific link and complete a trade (spot, margin, or futures) with a volume of at least $100. Users beyond the first 700 will share a pool of 5,000 IO tokens. The promotion has just started, so traders are encouraged to register and trade quickly to maximize their rewards.
