It's obvious that developers can't trust each other, based on the bug in the coin software. The coin developer was partly to blame.

But on a separate note, from the FYRSTIKKEN pdf:

CryptoRush will from now on have their customers cold-storage placed on Cryptsy,
JustCoin, Bitstamp, BTC-E, CampBX and other well known, well secured Bitcoinexchanges
as an extra layer of security, as we learned from MtGox - never have all the
eggs in one basket.

WTF?!!!! That's the funniest thing I have ever read!

Oh well, at least his 500k will go towards paying back the people who lost money.

It doesn't help if N is chosen to be a given multiple of the difficulty at the time a block is found. If the difficulty is about to increase, it is more profitable to mine a short while before. For example, if N is set equal to the difficulty D, a share submitted D shares before the increase will be paid the full expectation in the D-window, and then when difficulty increased it will once again go inside the window and have more expected reward.
