The protocol and cryptography that make up ziftrCOIN have a strong security track record, likely making cryptocurrency the most secure way to shop online. Malicious persons looking to disrupt the network would have to go through impractical efforts to gather both enough computing power and total coin amount to have significant power to sway the network. However, at that point the dishonest users would only be hurting themselves by disrupting the network. Any attack on the network would result in a decreased value attached to the currency, thereby reducing their own personal stake in the value of their coins.

The most common vulnerability to the system, however, is user error. Wallet files that store private keys can be accidentally deleted, lost or stolen. These issues are similar to physical currencies stored in digital forms. However, users can counteract this by implementing sound security practices to protect their money.
