How do you buy grt?

How exactly do I purchase GRT? Could you walk me through the steps involved in acquiring it? Is there a specific platform or exchange that I should use? Are there any fees associated with the purchase? Also, how do I ensure the safety of my investment and avoid any potential scams? Would it be advisable to consult a financial advisor before making such a purchase? I'm quite new to this field and would appreciate any guidance you can provide.
