One of the key features of Bitcoin is that its transactions are irreversible. Due to its independent nature, it cannot be controlled or manipulated by banks. Meaning no individuals, company or government, has control over your Bitcoins after you have sent them or received them. This can be seen as a positive or a negative effect. Without an undo or back button, it’s only possible to prevent fraud, not detect and mitigate it.

Banks rely on the reversibility feature every day to stop fraudulent activities. Bitcoin robberies and scam cases aren’t just rising because of interest in the currency but because robbing a bank online or scamming someone online involves much less friction then doing so in person.

To steal a million dollars from a typical business’s bank account, thieves would roughly need to transfer it to a network of roughly 100 money mules. Each mule must then withdraw less than $10,000 from their account within a short period of time, take the cash to Western Union, and wire the money to other thieves.

To steal a million dollars worth of Bitcoin however, it only takes one instant transaction for the Bitcoins to be gone and untouchable forever. Looking back over the past year we unearth the most significant Bitcoin scams.
