Where can I buy blz?

I'm interested in purchasing some BLZ tokens, but I'm not sure where to find them. Could you please guide me on the best platforms or exchanges where I can safely and easily buy BLZ? It would be great if you could also provide some insights into the security measures I should take when making such a purchase. Additionally, is there a minimum amount required to buy BLZ, and are there any associated fees that I should be aware of? Thank you for your assistance in helping me navigate the world of cryptocurrency.
