NEO, previously called “Antshares,” is often called the “Chinese Ethereum” because it has many of the same goals as Ethereum and is developed in China, unlike the majority of other cryptocurrencies that are developed in the U.S. or Europe. Being in China may also give it some advantages due to potentially improved relationships with both regulators and local Chinese businesses that may prefer adopting it over a Western cryptocurrency.

On November 21, 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USTD from their primary wallet.
