There is plenty of complaining in the Change telegram group. Most complaints come from Asian users and are; no news from developers, very small marketplace at the moment and revision of the roadmap with concrete steps / release dates. Once the app is full working and online, Change is a sleeping giant imo. They have a great concept.
Because I post that I have stepped into both the ico of Change and Bankera and compared them with each other I have been banned from the group without any warning. BASTARDS!
