How to buy Echelon without membership?

Could you elaborate on the process of purchasing Echelon tokens without being a member of a specific platform or community? I understand that cryptocurrencies often have their own ecosystems and require specific steps for acquisition, but in this case, I'm wondering if there's a direct method to obtain Echelon tokens without going through the traditional membership process. Are there any decentralized exchanges or alternative avenues that allow for the purchase of Echelon without prior affiliation? Your insight would be greatly appreciated as I'm interested in exploring this option.
