That means that if someone hacks the server hosting your wallet, your funds are secure. No one has control over your funds except you. User-owned private key wallets offer a much stronger option in terms of security. For this reason, keeping funds in a wallet for which you don’t control the private keys is significantly riskier than storing fiat currency in a bank. Unlike banks, however, crypto projects are not legally obligated to refund account holders their funds in the case of a security breach. However, this comparison fails to recognize key dangers inherent in third-party management of crypto funds.Ĭrypto wallets, like bank accounts and any other internet-connected account, are at risk of being hacked. The user is the owner of the funds but relies on the wallet’s server to execute transactions. This model is typically described as the crypto version of a bank.

Matt Miller, a Bloomberg TV host, demonstrated this lesson to the world when he briefly showed his private key QR code on-air and had his funds immediately stolen. For this reason, it is extremely important to keep private keys secure and confidential. Coins can be transferred to other blockchains only by accessing a wallet’s private keys.

Public keys facilitate the transfer of crypto private keys, their receipt. All cryptocurrency transactions are based on the control of two important numbers: public and private keys.
