Actually, there are lots of existing wallets so we cannot try all just to conclude which one is the best or which one is the worst to be used because wallet creators are making wallets to satisfy their consumers specification on how they can easily manage holding such cryptocurrency coins for their own sake providing that they are securing that their client's account are safe from bugs and hackers, we can conclude that this can be an efficient wallet. In my case, I am using the virtual wallet which is generated by our country just to cater the needs of my fellow citizens that are based on our specifications and standards on how we like our virtual wallet to be manage and used for an easy access. So, the goodness or effeciency of a wallet depends on its user because the reason why people change their preferred wallet is that their standard and specification does not fit on the wallet they are currently using so they keep on seeking for a better one.
