Both Crypto20 and Hyperion govern blockchain assets which are ERC20 compatible (the C20 token, and the IHF token). In other words, they are Ethereum tokens. We recommend storing tokens at a personal wallet, and we detail a few options below.
How to create a MetaMask wallet:
MetaMask allows you to run Ethereum dApps (decentralized applications) in your browser. We highly recommend using a Chrome browser, along with the MetaMask extension. Many sites are integrating with MetaMask to facilitate interactions within the Ethereum network.
Creating a wallet with MyEtherWallet
Another very useful and trusted Ethereum wallet, is MyEtherWallet. You can either work with it online, or download it and run it locally on your computer. It will work and look the same either way.
Make sure you see MYETHERWALLET LLC [US] in the URL bar before you access your wallet, or even better, type out the website address yourself. Do not click any links people send you to access MyEtherWallet.
Essentially, you need to check that you are at the correct website, with the correct SSL certificate. Provided that is the case, MyEtherWallet is a fine option for storing ERC20 tokens.
You can also store and access ERC20 tokens at addresses generated by hardware wallets. Common options include the Ledger and the Trezor.
Please see this guide for accessing Ethereum tokens on the Ledger.
Please see this guide for accessing Ethereum tokens on the Trezor.
