Not necessarily. If the 30% of the wallets that haven't updated are connected to each other, essentially they will still be processing "valid" blocks because their code says it's valid. They will fork off the chain into their own "valid" chain. I mentioned this a few pages back with the possibilities of what could happen with CM.
Luckily we have a majority of the wallets upgraded, so the impact should be minimal. The 70% will invalidate the 30%'s "valid" blocks. The blocks will hit the chain but be rejected before they are written. Now if we were sitting at a 50/50 split in versions or worse, or the majority of the hashrate was based on the old code and validating with older clients, we would be in for trouble unless we explicitly stated the MIN_PEER_PROTO_VERSION found here: https://github.com/nlgcoin/guldencoin/blob/master/src/version.h#L34. That line, combined with a protocol increase, would block connections from any wallet running an older protocol version.
I see that the protocol magic was changed in this code change, but I'm not sure if that has something to do with this whole discussion, but /GJ could probably shed some light on it.

So, I have only 1 28 Mhs miner. I am able to mine 400 NLG/day. I hope that Digishield wont change that, because that will have a reverse effect that you expect! Miners will leave if the diff will go higher then 1000 and wont come back, because that wont be profitable even with someone with free electricity!
Hope I am wrong and I can have near the same amount after digi kicks in!
My feeling says youre profit will be better. Pls let us know how you do after Digishield kicks in.
May I ask? Do you sell all the coins you mine or do you save some also for saving/investing/spending?
