Where can I buy a DYM token?

I'm interested in investing in cryptocurrencies, particularly in the DYM token. However, I'm a bit overwhelmed by the vast array of platforms and exchanges out there. Could you please guide me on where I can safely and securely purchase a DYM token? I've heard some platforms might be scams, so I want to make sure I'm doing this right. What factors should I consider while choosing a platform? Also, are there any specific steps I should follow to ensure a smooth transaction? Your insights would be greatly appreciated.
