How do I get GMX?

Could you please elaborate on the process of acquiring GMX tokens? As a cryptocurrency enthusiast, I'm keen on understanding the various methods to obtain this digital asset. Could you perhaps start by outlining the steps required for those new to the world of cryptocurrency exchanges? Furthermore, I'd be interested to know if there are specific exchanges that offer GMX, and whether it's available for trading pairs with major cryptocurrencies such as Bitcoin or Ethereum. Additionally, are there any considerations I should make before investing in GMX, such as market trends or potential risks? Thank you for your assistance in this matter.
