As a cryptocurrency enthusiast, I'm curious about the process of acquiring Ordi tokens on the DEX platform. Could you elaborate on the steps involved in making such a purchase? Specifically, I'd like to know if there are any prerequisites, such as having a certain type of wallet or account, and what kind of verification or approval process I might need to go through. Additionally, I'm interested in understanding the trading process itself, from initiating the buy order to confirming the transaction. Could you provide a step-by-step overview of the entire buying experience on DEX for Ordi tokens?
