[medre007]

Hello guys. Tomorrow i will buy Giant X10 but i can afford Z9 Mini too with x10.

Z9 mini has good profit for now but what about future? Should i buy it?

What is hard fork thing btw about bitcoin gold.

İ really need your thoughts thank you.

Basically you are taking a gamble that no coins will in the near future change their algo and render that ASIC useless.

Look at what happened with the Cryptonight ASIC that was released a few months ago. The XMR team changed the mining algo and it was useless for that coin.

I think if you got the ASIC early you might of made decent profits like $50/day but right now I think they are pulling in less than $5/day.

Hence the same future can be held for the Z9 Mini, and also think "Why are they selling this in the first place".

My advice, just buy some BTC and hold that instead. You will most likely make more money than buying the Z9.

Correct me if iam wrong but z9 can mine 20$ per day i was looking to mine zen cash and now days average is one zen per day thats good enought for me

Zen cash or Bitcoin gold?

There will be hard fork on bitcoin gold i guess. İm worried about that

[swogerino]

We have some negative precedents with the other dedicated ASICS before like D3 ,L3 and lately the Monero ASICS which are all worthless right now.

I think it would be better to buy bitcoin or to buy a mining computer with graphic cards in order to be part of the decentralisation, ASICS means centralisation for me so I am always against them and no one gives you a guarantee that Z9 will be profitable after 1 or 2 months.

[Vann]

ASIC's are about an arms race where only the newest and most powerful remain relevant. In my view you should ever buy a mini anything ASIC if you expect it to be profitable. More like buy the MAXI

What is average lifetime for this things i know they have 6months warranty but has anyone had any expirence with it?

Bitcoin gold already forked (yesterday?)

Only 77 Z9s have been shipped so far and I haven’t seen any report about failures. My batch 1 S9 shipped end of 2015 ( I forgot the correct date) still going strong. I had a couple l3+s out of 32 failed last year out of warranty but bitmain repaired them free of charge. So if you are lucky it will last a longtime.

How come a S9 going strong? Maybe you are talking that it is working but in case you have an energy price of 0.10 kwatt it is not profitable anymore. That happens because of the difficulty increase in bitcoin network which was 14% a few days ago.

Lasting a long time doesn't mean it will be profitable as explained above. Still though the Z9 with only 300 watt power consumption it is supposed to be profitable for at least a few months.

[smoolae]

I really wouldn't touch any ASICs anymore. We have had just too many "scams" by Bitmain and other ASIC manufacturers, you buy an ASIC from them and you basically never ROI when getting a batch 2+

I thought the question was strictly about longevity not profitability. Since you brought up profitability, a free dollar is a free dollar, my batch 1 S9s have paid themselves off long time ago and now laying smaller $1 golden eggs a day which may as well translate into bigger eggs when BTC appreciates 

[socks435]

Well if right now it gives you a good profitability why not buy the z9 and then holds your coins if the difficulty increases expect for the value of the coin decreases but you can still hold them and wait for the right time to sell them and make you profit.
right now there are many people and investors enter in mining business that is why the difficulty increases.

To me, I will stay building a mining rig because it supports more algo's than ASIC miners which is support less coins.
Mining rigs are flexible and you can mine any coins you want if the other coin is not profitable you can mine the other coin that gives you profit or you can mine coins and hold it for a long time and sell them in the right time to make you a huge profit.

Anyway, you can still buy it to test and learn because sometimes there are happy miners made a large profit before the price of the coins and difficulty increases.

Yeah, BM have been too clever for their own good.

Unless you get batch 1. You'll only just ROI on batch 2, then be left with a doorstopper. In some cases (see the XMR saga) you don't even get that. When you factor in the hassle and time spent playing fastest finger, shipping + fees, customs faff, warranty returns to China and then maintaining a dedicated noise-proof, power and cooling area for your asics, it's really not worth it at all.

Bitmain has been far too clever indeed if you ask me. They do it subtly and although it isn't as pronounced as the Cryptonight ASIC screw up, they are also playing tricks on Z9 purchasers. Sharing the computations one poster did on the difference in price from Batch 1 ($2000) compared to batch 3 ($850):

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.

Good luck to all those who will continue to support Bitmain's products. You are simply selling out your values (by buying from known tricksters) for a slim chance at profits.

[RentGPU]

Bitmain and their supporters will learn a good lesson in the nearby future , don't buy any of thier products , why do they sell it in first place if they can make more money running it

[leowonderful]

The fact that people are already selling below the first batch price of $2000 for in hand Z9 Minis in the Computer Hardware section shows a lot about this miner already- probably not the best idea to get one. It's beyond a gamble right now with Bitmain ASICs- you're just throwing your money away by buying them, especially when there's plenty of negative feedback from miners like the B3, A3, D3; basically every alt miner Bitmain has ever released recently besides the L3+. I don't see why people think 'this time'll be different' on every single new release from Bitmain.

[changase]

I am making 1.5 ZEN per day with my Z9.
It's very good profit so far

[Kahooli]

I'ts a solid product so far. I got what I paid for. But I would not be so quick to buy a batch two one... especially in this down markey
