How to buy DGX with Crypto?

I'm curious about the process of acquiring DGX using cryptocurrencies. Could you provide a step-by-step guide on how to do this? Specifically, I'd like to know which exchanges support the trading of DGX, the necessary steps to set up an account on those exchanges, and the specific procedures for converting my existing crypto holdings into DGX. Additionally, I'd appreciate any tips or considerations I should be aware of before making this purchase, such as transaction fees, security measures, or any potential risks involved. I'm relatively new to this space, so a detailed explanation would be greatly appreciated.
