>You don't see a problem with scam instamining 2+ million coins

I believe that coin creators (developers) don't need to work for free. They need to be paid.
Pre-mine or insta-mine is one of the very few ways to make some money for coin developers.

Crypto-coin development is one of the 5 hardest dev jobs on Earth. Those include: operating-systems (Windows, Linux), virtualization (VMware, VirtualBox), 3D games, Artificial Intelligence (A.I) and crypto-coins.
Very few developers can even understand it, let alone hack it's code and make significant improvements. Evan Duffield (of Dash) and Vitalik Buterin (of Ethereum) are one of the few, who can.

And if we don't pay (the investors), then BlockStream will attack our coin !
