The rise in the value of cryptocurrencies has inevitably drawn the eye of criminals, and the concentration of crypto in the cryptocurrency exchanges has focused that attention. Coinbase is the largest exchange in the U.S., and researchers have detected numerous phishing campaigns against Coinbase users.
The size/value of Coinbase is impressive. It claims to have more than 56 million verified users in more than 100 countries. Its traded volume is around $335 billion, and it has $223 billion in assets on the platform.
