Great question! There isn't an ATM for it yet. We recommend downloading a crypto wallet and exploring which apps offer access to the cryptocurrency you're looking for.
Since we'll be launching our NFT collection on Opensea.io there are a number of crypto wallets that can be used on their platform. If you intend to use your desktop for managing your cryptocurrency then we recommend Meta Mask. It's wildly popular and secure. They do have a mobile version as well, but you get more options using their desktop version. Check out their introductory video for more information.
Another great option, with an even better user experience, is Coinbase. There you have the ability to swap and store your NFTs all in the same place. Coinbase allows you to explore the decentralized web with a dapp browser. Another secure choice that keeps everything important to you in one location.
Lucky for you, Opensea supports a multitude of cryptowallets. Find one that works best for you here.
