Exodus.io
Exodus is a community favorite multi-coin wallet, it is lightweight, user-friendly and offers one of the most attractive user interfaces of any wallet. While not 100% open source, many of the wallet functions are open source and the developers are working towards becoming open source at some point. Because this wallet is not 100% open source, this may not be the best option for storing very large amounts of cryptocurrency. Large amounts of cryptocurrency are usually best stored offline, using cold storage practices. This wallet allows users to hold a variety of coins, including Aragon, Augur, BAT, Bitcoin, Bitcoin Cash, Civic, Dash, Decred, District0x, EOS, Ethereum, ETH Classic, FunFair, Gnosis, Golem, Litecoin, OmiseGo, and SALT. These coins can be displayed as a portfolio, showing your whole crypto net-worth, or individually displaying the current value of each coin vs the value when you received the coin. This is a very simple program to use, with a very secure backup and restore feature, requiring only a “seed word”. Note: A seed word is a 12-word passphrase, that will allow you to restore your entire wallet should you lose access to your computer. It is very important that you copy your seed word and store it in a secure place, should you ever need to restore access to your wallet.
