This paper is aimed at a detailed study of the behaviors of random walks which is defined by the dyadic expansions of points. More precisely, let x=(ϵ 1 (x), ϵ 2 (x),…) be the dyadic expansion for a point x∈[0, 1) and S n (x)=∑ k= 1 n (2 ϵ k (x)− 1), which can be regarded as a simple symmetric random walk on Z. Denote by R n (x) the cardinality of the set {S 1 (x),…, S n (x)}, which is just the distinct position of x passed after n times. The set of points whose behavior satisfies R n (x)∼ c n γ is studied (c> 0 and 0< γ≤ 1 being fixed) and its Hausdorff dimension is calculated.
