Using the same keys across different altcoins seems like an exceedingly bad opsec practice. Cointype is critical, as well as having a predictable and deterministic mapping of alt coins to Cointype. What should I be using for Catcoin, for instance? the CAT symbol all the exchanges use, or do we set up a 'registry', or some other mechanism? I'd venture to guess the altcoin market is, or soon will be larger in US dollar value trade volume than Bitcoin, so *some* of us are quite bothered by the wailing and gnashing of teeth that occurs on this list at mere thought of such heresy. -- ---------------------------------------------------------------------------- Troy Benjegerdes 'da hozer' hozer at hozed.org 7 elements earth::water::air::fire::mind::spirit::soul grid.coop Never pick a fight with someone who buys ink by the barrel, nor try buy a hacker who makes money by the megahash
