BTC/Altcoin -> Counterparty -> DRK
DarkSend that shit
Darksend that shit again (why not?)
DRK -> Counterparty -> BTC/Altcoin
Basically, use DRK for the DarkBank and then just withdraw it as you need it into the other cryptos. That's my plan, anyway.
I should add, the whole point of Dark is that the mixing is decentralized. In order to accomplish what you and the other guy are pondering, you must trust 3rd parties again, which isn't optimal.
I agree that it's not optimal, or even desirable... I wonder what would happen if you exchanged BTC for DRK in your own wallet at your own rate... It seems like holders of large amounts of any currency could then drive the price wherever they wanted... But then, do they do that now?
