Enough to make you reconsider the expiring addresses idea?
Or does having the expiring addresses help your operations somehow? I'm not trying to be a d***, I'm just curious why you made the switch. Seems like Mtgox has been operating fine allowing old addresses to be re-used.
Excellent question: MtGox and CampBX are architecturally different. We handle all Bitcoin transactions in real-time and ensure full synchronicity with P2P network at all times. This has major advantages in terms of security and redundancy, but it does take a toll on performance.
Disposable addresses is a stop-gap solution which helps performance significantly. We are working on developing and testing a more permanent fix.
