Pre-mine seems a little large, if it had been smaller we may have looked at adding you to CryptNZ.
To put in perspective, you would have to mine every single block for roughly 5 days to have the equivalent to the same as the pre-mine (at the 200 reward per block) which is equal to ~3387 Blocks.
The problem with the pre-mine is that we have no control over how it is spent. It could be spent in any which way and they could just say that they paid someone to do some work.
