It would be cool to have other coins on the same wallet that could be shared maybe using our steemit account names.. Maybe say for example litecoins private key would be cyptic in our normal steemit private key. This could be a cool development since steemit has become life and no ones wants to have multiple wallets. This would also making trading coins or paying for things a lot easier. My only issue is that not everyone wants their coins so public and linked to their identity.
