This study evaluates the adaptive market hypothesis (AMH) and evolving return predictability in bitcoin market. We use two robust methods in a rolling-window framework to capture time-varying linear and nonlinear dependence in bitcoin returns. We find that market efficiency evolves with time and validates the AMH in bitcoin market. (C) 2018 Elsevier B.V. All rights reserved.
