I think people with the first batches will be able to make 3000-5000$us for the first month of use. Then it will drop fast to 2200$ then 1500$us etc...
This is why im saying, that the 3rd batch from Bitmain will be useless. Even if you buy 10 machines, you will end up making 10k a month or something.
Imagine now, the difficulty is at 300,000-500,000 . And this is the result of hundreds of miners mining with 150mh/s , 300mhs and 900mhs miners mostly...
Imagine now , you have over 600 machines deployed in September, and each deliver not 150, 300, or 900 , but 15,000 mhs each.....
Go figure....
2000$ and 1500$ is not bad for a 2500$ miner.
People still buy the L3+ for October for 1700$ or pay premium to get them now when they make what 1000$ profit in ltc per month.
Plus maybe the lower the price for the 3rd batch if it ships later than 18th-30thj September like they did with the 2nd batch of L3+
