Crypto prices seem to be on an unstoppable upward trend. With Bitcoin and Ethereum hitting all-time highs again this month, more and more people are investing their money in digital currencies. And there are plenty of ways to keep your investments safe.

Cryptocurrencies are sold in a so-called a. saved walletthat is assigned a private key similar to a password. The easiest way to get your coins in a wallet is with the cryptocurrency exchange you used to buy your currency (think Coinbase or Gemini). But more mainstream companies like PayPal and Robin Hood, have also added options to buy, sell, and hold crypto.

Crypto owners who want complete control over their investments can also rely on digital wallets that are managed by software locally on the user’s own device. For an extra layer of security, you can use something called a cold wallet, which is essentially a local device like a hard drive that is not connected to the internet.

Companies like Secure and Ledger make special drives specifically for cryptocurrency wallets. The companies say that even when the devices are connected to your computer, sensitive information is not disclosed (just don’t lose the device or the key that is needed to access the data on it). Check out the video above for a detailed look at how all of these options work.
