You do realize, don't you, that a lot of the time when you're trading with a bot on one exchange you're really trading with a human on another exchange via an arbitrage mediated by the bot?
I guess if you want to have your little walled-off exchange that is an island unto itself, fine, but I think you're alone in that desire. If you want that, use litecoin.
Yes, that's an issue too, but unlike BTC-withdrawal-via-API it is caused by the brokenness of the banking system as a whole rather than the brokenness of one particular exchange's operators.
Sorry I did not see your post earlier, because there was something else I wanted to add. I notice the $350,000 loss over on bitcoinica was (apparently) an api hack. Perhaps Crypto are happy with being different. It's still a pain extracting funds, but it still works.
Also, for clarification, I don't use bots (I must be too stupid), and I like the exchanges I use and arbitrage, but mostly just cashing profits. As for altcoins, no thanks - that was a passing curiosity with i0coin with a difficulty under 14. If I'm alone with my view, that's fine. I see you have several good and highly technical projects that work well and certainly other people also like automatic trading.
As a warning, if you get a Starfish deposit account, the security means you don't get to interrogate your account. You actually have to communicate with someone.
