Where can I buy tectum crypto?

Excuse me, I'm a bit new to the world of cryptocurrencies and I've been hearing a lot about Tectum lately. Could you please guide me on where I can purchase Tectum crypto? I've checked a few popular exchanges but haven't found it listed. Are there any specific platforms or marketplaces that offer Tectum for trading? Also, what are the usual steps involved in buying a new cryptocurrency like Tectum? Would I need to set up a wallet first? Any advice or tips would be greatly appreciated. Thank you for your time.
