It also helps to prevent insta-mining

Which was the thing making launch coins profitable. Now nobody has a lot of coins except maybe the devs have what they premined. No whales -> no volume -> no trading -> no value -> no miners -> coin dead.
We were the first to setup and accept pre-registrations and are still taking on new miners for the launch later today!
Whoop-de-doo.
this, get rid of that difficulty algo at launch, it kill the point of mining new coins altogether....
