How to buy WTAo?

Excuse me, could you please elaborate on the process of purchasing WTAo? I'm a bit new to the world of cryptocurrency and I'm not entirely sure where to start. Do I need to create an account on a specific exchange? Are there any specific steps I should follow to ensure a smooth transaction? Additionally, is there a minimum amount required for purchasing WTAo, and what are the associated fees I should be aware of? Your guidance would be greatly appreciated.
