I have had enough of this nonsense.
Almost $3.8 K tariff+fees on four Z9.
This plus $14.5K on Z9+PSU itself means that I am out of $18.3 K before they even started hashing.
$18.3K buys 165.5 ZEC without a penny spent on electricity making the whole affair foolish because four Z9 would NEVER make this amount.
Fooled by Zooko, Bitmain, etc.
Fool me once...
No more orders of any kind, especially from China.
And let's suppose you want to sell them on ebay. your minimum price is around 5200 just to break even... 3500 for miner+shipping+PSU, 950 for tariff, 3% for paypal fees, 10% for ebay fees.
... or maybe they overclock to 100kSol?
Yup, screwed.... I mean, look at the opportunity to mine! Buy mine from ebay today!
