When will our refunds come through for spending $2000 on these $850 miners!!!!

You will earn more than the difference in the time between the batches, especially if you OC.

Not really. It still doesn't make much sense to screw over batch 1 investors. Here's the math behind it:

$2000-$850 =

**$1150** <- total difference that you need to make up

Estimated profits (ASIC is OC-ed to 15k sols, conservative)

1st week of mining: $30 per day * 7 days = $210

2nd week of mining: $25 per day * 7 days = $175

3rd week of mining: $20 per day * 7 days = $140

4th week of mining: $15 per day * 7 days = $105

5th week of mining: $12.5 per day * 7 days = $87.5

6th week of mining: $10 per day * 7 days = $70

7th week of mining: $8 per day * 7 days = $56

+ 8th week of mining: $6 per day * 7 days = $42

-----------------------------------------------------------

Total value mined after 8 weeks (2 months = equal time to receive new batch orders which only cost $850 per Z9 ASIC) =

**$885.5**You would have earned more if you just waited and bought the $850 version. To be specific you would have $300 ($1150-850) more if you simply buy the latest batch. Fu bitmain.
