Decentralized exchanges and anonymity coins are at the top of my list when it comes to what we need right now, anonymity coins are needed because even if bitcoin is great we need a way to transact money online without everyone finding out in what we spend our coins and decentralized exchanges are needed as well since I want to be able to buy other coins without having to rely on a centralized exchange that asks for all kind of information that I do not want to give to them.
