Heh man this thing has been a disappointment.

Takes like 5 minutes to start hashing, reporting is so outlandish they'd be better off not even showing local hash rate (I've seen as high as 25GH shown locally), loud as shit, has rejected shares at stock clocks, barely delivers advertised hash power, can't over clock it, I could go on and on.

Guess I'm just spoiled from the super simple/reliable BitMain GUI that actually reports properly.

Anyone want to buy mine? Already state side, tariffs paid, $4500 shipped.

Yeah, its not super great.  Bitmain has a massively better UI and UX.  The local hash rate info is a joke... but if you let it run long enough the hourly trend is more helpful, but I tend to agree that this is not a well designed miner.  Hopefully there is a firmware update that corrects some of the issues, but I am not holding my breath.

you actually probably CAN overclock it if you manually change the config files to greater than 900 mhz... but overall I agree with your assessment.

(PS... you complain about it then offer to sell it at nearly full price??  I love that...lol)


Cheapest ones are over $5000, + 35% import tariff + won't ship for another week because of the Chinese holiday etc.

I have no doubt itll easily do ROI as quick as its advertised, despite my complaints I'm still averaging $80/day, plenty of people out there not as picky as I am lol.

If someone wants it cool, if not, I'm not sweating it.


Hope Bitmain dumps a better and cheaper one in our laps. The price is not worth the risk, at all...

It arguably has the fastest ROI out of any ASIC on the market right now, if anything its a lower risk than the majority of ASICs out there, so I'm not really sure what you mean lol.



35% tarriff?  Where do you live??

I ordered mine from a chinese supplier at $4600 with a $108 shipping fee and paid no import or customs fees.

I am not seeing the $80 per day, but I am not mining individual coins currently, but it looks like via nicehash I get between $60 and $70 depending on how my hashrate is, which is a bit lower than advertised.  But even at a 90 or 100 day day ROI, I am happy (ish).

My biggest complaint is really noise.  It is higher pitched and louder than my other miners, so I am building a sound dampening box this weekend (about $70 in additional cost, and a few hours).

Either way, if you can deal with the frustration and very little support, its not a terrible purchase, just more difficult than what can be expected from bitmain.

Uhm, good ole USA, they were just hiked another 10% on Sept 24th up to 35% from 25%, the only reason you didn't get hit with tariffs is if the company you purchased the miner from lied about what you paid for it, which is illegal, but the risk is on them, not you, so just consider yourself lucky that they were willing to lie about it lol.

Any invoice over $1000 is flagged by customs and subject to import tax.

Friend of mine ordered 2 Z9 Minis on the same ticket, was just over $1200 , ended up paying $366 in duty fees, fees on a Dayun are ~$1500 if they catch it.

I don't think this is correct...Unless you operate as a business instead of as a hobby.  There is a personal use exception for most goods.  The company that sent it to me listed it as a personal computer (which is fairly accurate) with the full value and it cleared customs in 6 hours and I did not owe any fees.
