Arguably there is no need and alt coins could just use\n\u003e    the same keys as Bitcoin, but it may help avoid confusion if they don't.\n\nUsing the same keys across different altcoins seems like an exceedingly bad opsec\npractice. Cointype is critical, as well as having a predictable and deterministic\nmapping of alt coins to Cointype.\n\nWhat should I be using for Catcoin, for instance? the CAT symbol all the \nexchanges use, or do we set up a 'registry', or some other mechanism?\n\nI'd venture to guess the altcoin market is, or soon will be larger in US\ndollar value trade volume than Bitcoin, so *some* of us are quite bothered\nby the wailing and gnashing of teeth that occurs on this list at mere thought\nof such heresy.\n\n\n-- \n----------------------------------------------------------------------------\nTroy Benjegerdes                 'da hozer'                  hozer at hozed.org\n7 elements      earth::water::air::fire::mind::spirit::soul        grid.coop\n\n      Never pick a fight with someone who buys ink by the barrel,\n         nor try buy a hacker who makes money by the megahash"}
