Binance is the best exchange for everyone but it seems they don't care every trader rather only the rich one! They are making rich people richer when they have no plan for every type of trader! Binance is giving away 1.1 Million USD worth BNB coin to them who will trade over 1 Bitcoin with some rules! I really don't like this type of movements!
Simple, the trading competition is for those who have 1 Bitcoin, why don't you like it? This is not the first trading competition from binance and it won't be the last, it's not as if every binance trading competition requires only 1btc upward, you can also participate on KUCOIN as well, they have lower trading competition for people who don't have much
Based on the reference that @Bttzed03 provided it's totally a trading promotion for their platform and it seems that only traders who have a huge amount of capital can only benefit from it. If you are an average trader on their platform maybe you can earn at least a few amounts of BNB but, if you are below average traders don't expect that you will receive BNB from their giveaway. I'm pretty sure that the whales will totally participate in their giveaway. To OP if you can't afford the amount required from their promotion or giveaway, try to look at other exchanges that have this kind of promotion and for sure, you can now participate with it.
