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.
I was looking for trezor and ledger nano s and one people on the forum addressed me to KeepKey. I'll check that out soon. There are many attacks and fraud. So a hardware wallet is needed at the moment. Hope, next time, they (ledger and trezor) make their stock wider.
