Where can I buy BlackCoin?

Excuse me, I'm interested in investing in cryptocurrencies and I've heard about BlackCoin. Could you possibly direct me to where I could potentially purchase this digital asset? I've looked around online but there seems to be a plethora of platforms and I'm not sure which one is the most secure and reliable. Could you perhaps provide me with a brief overview of some of the more trusted exchanges that offer BlackCoin trading? Additionally, are there any specific steps I should take to ensure the safety of my investments when buying BlackCoin? Thank you for your time and assistance.
