After all, the principle of storing private keys (both on a flash drive and through cold storage) works for most coins — BTC, ETH, USDT, ADA, PAXG, etc.

In the world of digital assets, control over private keys = control over money. If you are holding cryptocurrency long-term or want maximum security, consider cold storage — offline storage. One of the most accessible ways is to save keys on a removable storage device (USB flash drive, SD card, etc.).

What is cold storage of cryptocurrency?

Cold storage (cold storage) is the storage of private keys, seed phrases, or wallets in an environment without internet access. This method significantly reduces the risk of hacking, malware attacks, or phishing.

Suitable for most cryptocurrencies, including:

  • Bitcoin (BTC)

  • Ethereum (ETH)

  • Tether (USDT)

  • Pax Gold (PAXG)

  • Cardano (ADA)

and others that support self-custody of keys

How to store cryptocurrency on a flash drive?

Option 1: Wallet with file on a flash drive

  • Create a wallet in the program (for example: Exodus, Atomic, Electrum, MetaMask, depending on the coin)

  • Export the wallet file or private key

  • Write it to the flash drive, which you disconnect from the Internet

  • (Optional) Encrypt the flash drive with VeraCrypt or BitLocker

  • Save the seed phrase separately on paper or in a safe

Do not store keys in plain text on a PC or the cloud.

Option 2: 'Paper wallet' on a flash drive

  • Open an offline wallet generator, such as bitaddress.org or walletgenerator.net

  • Generate a key pair (address + private key)

  • Save the .HTML or .PDF file on a flash drive

  • Disconnect the flash drive and never open it on an internet-connected PC
