Do you know that after 3000 blocks * 90 sec (form now on) = ~75 hours later production will drop sharply.

What's sharply? What's the subsidy now and what will the new subsidy be? Thx.
Average 500.000 per block will drop to 300.000 in ~72 hours.
Man, I don't consider 40% sharp. 90% would be more like it but that's still massive inflation.
That said, don't expect anything with only a 40% drop in inflation.
I really can't believe the devs haven't killed the inflation yet with a simple code update. Take it down to 50,000 [or less], a 90% drop.
Many coins have done it with positive effects.
Cheers!
