Why do people use GMX?

Could you elaborate on the key reasons why individuals and investors choose to utilize GMX? I'm particularly interested in understanding its unique selling points that set it apart from other cryptocurrency platforms. Does it offer lower trading fees? Faster transaction speeds? A wider range of cryptocurrencies to trade? Or perhaps it's the user-friendly interface and robust security measures that draw people in? I'd appreciate a concise yet comprehensive overview of the key factors driving people to adopt GMX for their cryptocurrency needs.
