Has the mystery of wild swing oscillations for the bitcoin price been solved? A very interesting study published by the scientists from Yale University, Professor Aleh Tsyvinski and economics Ph.D. candidate Yukun Liu claims that there are “good and bad times” to buy and sell bitcoins.
There has been thousands and thousands of scientific (and not so scientific) studies on the predictors of the stock market starting with simple moving averages and ending with the correlation between winning teams in Super Bowl and the behavior of S&P 500. However, this study is quite different. While the past performance, as we all know, is not a guarantee of future results, these scientists have discovered two non-trivial statistical phenomena:
1. The “momentum” effect. This is rather simple: if the price of the bitcoin increased for one week very sharply, it will continue to increase next week; the same is true for the price movements in the opposite directions.
2. The “investor attention effect”. More searches on Google are done for the term “bitcoin”, sharper the increase in price. And, for example, the searches for “bitcoin hack” predict a decrease in price. The correlation between such searches is far from insignificant.
