If ever any of the other chains goes onto a fork or does a blockchain rewind, any floating XCP that got sold would end up being able to be double spent.
Maybe this is a rare enough thing, then again, didnt DOGE just have one of these? The stability of XCP would end up being the stability of the weakest chain it ever floated on

Perhaps it would only be implemented on certain chains that are expected to be secure and stick around for the long run, rather than able to have XCP on every random BTC/LTC clone. There could be 3 maybe. BTC for security, doge or litecoin for transaction speed and then maybe something else which allows relatively large data storage or something, idk. But really though, anything could happen to anyone or any coin at any time (fork, attacks, price crash, whatever). BTC is just the hardened veteran
Yeah. You'd need every Counterparty client constantly talking to the servers for every single altcoin it was running on. And you'd have to implement a strict system for ordering blocks across chains. You'd also have to come up with a good system for sending funds across chains, because the addresses are not compatible and Counterparty right now stores the destination of transfers in its own output.
BTC is much more secure than any other coin, as far as I can tell. On multiple blockchains, Counterparty would only be as secure as the weakest of them.
