Could you elaborate on the process of purchasing KCS tokens in the Trust wallet? I'm a bit unfamiliar with the steps involved, and I'd appreciate a step-by-step guide. Specifically, I'm interested in knowing how to set up the wallet, ensure security measures are in place, and navigate the platform to find and purchase KCS. Additionally, are there any specific fees or considerations I should be aware of before making the purchase? Your assistance in clarifying this process would be greatly appreciated.
