received the miner ... directly set up and start mining ...
got only 64 USD per day

Mine arrived Yesterday after noon, set it up and was mining 115 sia per hour initially. By this moring it was down to 85ish sia per hour. My guess is the bulk of these have now arrived and set up and should settle somewhere around $50 per day. Really wish I used Fedex as those were arriving 4 days ago, but I went with UPS and a damn $72 import fee.
I always use fedex now , cheaper and faster
what else you can ask

Yeah, it seems it went FedEx (first deliveries), UPS second, DHL third from all the posts I'm reading.
Usually that is true for me too, but this time UPS delivered within two days of the miner shipping (which happened more like 7-8 days from payment), so I'm pretty happy this time around. But yes, i should probably use Fedex if I order from Bitmain in the future.
