the price drop and bear market last year was a major factor in difficulty dropping because it became more expensive, if 75% of mining is coming out of china unfortunately the usa is not the center of the mining universe, what so ever ! my opinion anyway .. bitfury up here in canada churns out a lot of custom servers for company’s as well.

2 years ago i got away with a batch of 10 s9is and i guess bitmain didn’t include a slip for value and when dhl contacted us about the value i said they were warrantly replacements 200$ value each and dodged most of the duty lol not sure how they screwed that up but was a blessing.
