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.
At the moment we are in the Apollo-phase. Read the previous posts to get the real number of coins mined at the moment (~2.5 million/block) and the timeframe when it will go down again - which is much longer than 72hrs.
Edit: billion/block to million/block
