Key facts card: Private keys and addresses
Bitcoin and Ethereum private keys are essentially large 256-bit random numbers, and both use the secp256k1 elliptic curve.
Avoid exporting your private key if possible. If you really need to back it up, don't copy it into a note-taking app connected to the internet.
