In 2016, this became apparent with the DAO hack. One way to fix the problem was to implement what’s known as a “hard fork,” which would essentially update the Ethereum-based software to fix the technical gaffe that caused the hack to begin with.

Various factors can be used to monitor usage of a subreddit. Due to the promising trading strategy generated from the factors chosen in [7], these same factors will be examined here. Posts per day indicates the number of posts made on a particular subreddit, per day. (this factor does not include comments made in response to particular posts). Subscriber growth indicates the number of new subscribers that a subreddit receives, per day. New authors indicates the number of new authors posting on a particular subreddit, per day. This current work will aim to confirm the relationship the factors identified have with price in a model-free environment, rather than with the use of a trading strategy which can potentially introduce ambiguity relating to individual factor contributions.
