Reuben Grinberg, a recent Yale Law School graduate now in private practice in New York City, discusses his paper, published in the Hastings Science & Technology Law Journal entitled, Bitcoin: An Innovative Alternative Digital Currency. Grinberg first gives a brief overview of Bitcoin, the decentralized, digital currency. According to Grinberg, Bitcoin can maintain sustainability, even though it is not backed by an institution or commodity, but it must overcome several hurdles. Grinberg then discusses the potential security problems and legal issues Bitcoin faces. He also describes some of the unique qualities of Bitcoin, including the ability to conduct transactions anonymously. Grinberg ends the discussion with his thoughts on what Bitcoin could potentially become.
