second, if you send a transaction now, it takes wayyyy wayyy longer to get 120 block confirmations than it did -- say 1 month ago even.. This needs to change. Screw it, even if it takes a 1 or 2 decimal hit right now it brings us that much closer to better microtransactions and more confirmations and 50 bitcoins can still be awarded so people don't feel like mining isn't profitable
I don't really understand what you mean by that, but statistically blocks should be created (and thus transactions confirmed) at about the same pace as always... Or what else do you mean?
