Topic: Questions regarding ANTMINER U3 (Read 1540 times)

Sound good. A bunch of the Antminers come with built in controller so you pretty much just plug them in and you're done. Its mostly plug and play. Just need to check in your router's DHCP list which IP it assigned to the miner when the miner is in DHCP mode.

Pop the ip in your browser and you can change the pool and configs(for most newer units) there.

Some other company's miner have built in controllers but not all.

well I wanted something that consume a little space and costs as little as possible as I'm short on the budget as of now and same time to be able to understand asic miners since I only mined with my GPU's in the past , after the help of those who answered my questioned in this thread , I came up with the conclusion that ANTMINER U3 is not that much worth since I only profit a little from it on a daily basis , so I'm going to save money for a bigger single unit hopefully

Dare i ask, why go with U3's?

They seem pretty pricy and require tons of wires and other stuff.

Is there a reason you don't want to get a bigger single unit?

try them.

Thanks for the suggestion but it requires at least 20 orders of ANTMINER U3 which I can't afford at the moment , but I will have this on mind , thank you

Number six
I think a direct order from bitmaintech may work.  Www.bitmaintech.com

You have no idea how much you just helped me , I was searching for answers for days and couldn't find any , I believe all my questions where answered with you , even the number 6 , thank you so much , I really appreciate the effort and all the help you did for me , Hopefully one day I can return the favor , thanks again

Yes, but keep in mind they can be notoriously temperamental and may need babysitting: https://bitcointalk.org/index.php?topic=827356.new;topicseen#new

You mentioned that you have free electricity, so the answer is generally always going to be yes (as long as it doesn't die on you) and the question is only one of "how long will it take".

Somebody's gonna come complain about your use of the term ROI here; https://bitcointalksearch.org/topic/roi-is-not-payback-period-1113417
Let's assume you meant break-even

Assuming...
1. the difficulty stays the same
2. hash rate is 63Gh/s (good luck)
3. price is BTC0.10453 ($30 at $287/BTC - adjust as necessary for 2nd hand units, shipping, etc.)
4. you only care about the BTC figures (saves arguments on exchange rates, whether it'd be better to buy BTC, etc.)
5. 0% pool fee
6. difficulty of 52,278,304,846
7. block reward of BTC25
...then it's about mid-way November; google 'bitcoin mining calculator', make sure you plug in all the various values.

https://en.bitcoin.it/wiki/Difficulty#How_soon_might_I_expect_to_generate_a_block.3F
( using the simplified formula )
time = 52,278,304,846 * 2^32 / 63,000,000,000 = [whole bunch of seconds] or roughly 114 years for a block, or ~4 years for BTC1

Note that next year (2016) the block reward will be halved from BTC25 to BTC12.5 as well, which means it will take a good bit longer than that even if the difficulty were to stay the same.

With the same assumptions as before, roughly BTC0.0006061/day

Can't help you with Q6 - doesn't appear to be an middle-eastern section and the Iran thread is pretty quiet, but apparently there is an Iran-specific forum where you might try asking as well: http://btctalk.com/forum.php

back in the days (2012) I used to mine with my GPU and even then it wasn't that profitable for me so I stopped , and now I want to get back and I want to buy and use ANTMINER U3 for mining bitcoin since i'm on a tight budget now


1) Can I just plug ANTMINER U3 to my computer and let it mine while I use my computer for normal use?

2) Will it be profitable with the current difficulty if it doesn't rise?

3) How long is the return of investment on it with it's 63GH/S ?

4) How long it will take to mine 1 BTC with current difficulty?

5) How much I could earn daily with it in terms of mining bitcoin for 24/7 ?

6) Right now I'm residing in Iran , do you know a shop which I could pay in bitcoin and have them delivered to me? If yes , kindly state the details regarding shipping fee's , thanks

Note *
I do have a free electricity so that's not a issue for me , thanks
