The Dogecoin Core wallet is said to be the official wallets of the Dogecoin Network. This wallet is said to be versatile as it is supported on both personal computers and mobile phones. For my experience using the wallet, I made use of its Android mobile app which is a lightweight up taking nothing more than 3.8 MB. The wallet has features that beat that of many other dogecoin wallets I have been seen around. It features a good user interface which is easy to understand and navigate. While making payments, I could easily make use of a QR code scanning instead of long strings of letters and numbers which makes transactions more feasible and easier.
Being a decentralized wallet, I was able to store my private keys in the form of a QR code on my mobile phone directory. I have so far only use the wallet to receive a transaction but I'm yet to send any so the fee structures for making or sending transactions are yet to be known by me but being decentralized I believe it could be toggled. The use of the wallets can be simplified according to them through Bluetooth transfer which I tried but didn't work out and the exchange rate features which is being displayed on the app doesn't work either.
None the less it is still a good wallet for users to store their coins as I am seeing to making use of the wallet in a long-term basis.
