-Lyn Alden, November 2017 Within the next month or so after the original article, Bitcoin briefly soared to reach $20,000, but then crashed down to below $3,500 a year later, and has since recovered to bounce around in a wide trading range with little or no durable returns. I’ve updated the article from time to time to refresh data and keep it relevant as changes happen in the industry, but other than keeping an eye on the space from time to time, I mostly ignored it.
