The best wallet i think is bread Wallet. It only available for IOS devices like Iphone hence it is provided with extra security.
In Web Wallet, Xapo is the best and coin base is on number two. However i haven't heard anything good about Coin base.
i never hear about bread wallet,tell me about it and why you choose this wallet?
i just think blockchain still the best choice,but i'm not sure if in future blockchain will stay the best,xapo,coinbase,mycelium and multibit have good feature to become better and the best.
