Where can you buy Chainlink?

Could you please enlighten me on where exactly can I purchase Chainlink? I've been hearing a lot about its potential in the crypto space, but I'm still not sure about the best platform or exchange to acquire it. Are there specific exchanges that are more reliable or offer better deals for Chainlink? Also, is there anything I should be aware of before making a purchase, like transaction fees or security measures? I'd appreciate any guidance you could provide.
