# Distribution for random harmonic series

Consider random variable $X$ formed by the following infinite series: $X = \pm 1 \pm \frac{1}{2} \pm \frac{1}{3} \pm ... \frac{1}{n} ...$, where $+$ or $-$ sign for every summand is chosen independently w.p. $1/2$. What is the distribution of $X$? If it is not some well-known distribution, does it have any interesting properties?
