Before revision:  In this paper, we show that the behaviors of price fluctuations in emerging cryptocurrency markets can be characterized fairly well by a Levy's stable distribution with alpha = 1.4 , which indicates fatter tails compared to a Gaussian distribution.
After revision:  In this paper, we show that the behaviors of price fluctuations in emerging cryptocurrency markets can be characterized fairly well by a Levy's stable distribution with \alpha \simeq 1.4 , which indicates fatter tails compared to a Gaussian distribution.
