There are a couple options for wallets that store multiple alt coins.KeepKey is a hardware wallet that can store about 5 different alt coins in the most secure way possible in the crypto space. KeepKey is integrated with ShapeShift so you can seamlessly trade between the alt coins that are supported.Jaxx is a mobile wallet on both iOS and Android. Jaxx is capable of holding about 6 or 7 alt coins and is seamlessly integrated with ShapeShift for trading between these few cryptos. Jaxx is a great wallet for holding these coins while still maintaining access to them all.A new service is also about to launch called, Prism. This is a service that allows you to use Ethereum to collateralize a digital asset portfolio with the help of Shapeshift. This acts as a sort of online wallet that stores alt coins and it is going to be a huge step forward for the crypto space.Unfortunately, the two wallets I mentioned above only hold about 7–10 currencies between them all so if you want to hold any of the roughly 600 alts, you will need to do some searching for wallets that can hold them. Prism is going to change this.
