one of my L3, after running over 2 days, capturing 380++ and another board is 170++.

Is that normal?

Yeah, its should place sales on Tuesday, but seem come early.
Seem this weeks so many batch launched by bitmain than normal rate in this several month.
I dont see any pressure to have such sales, or its because demand is fade?
I know their sold out everytime but it should because of increasing speculator buyer that order but lack of payment done.

I just placed an order for 2x L3's for mid Nov for 1.3 bitcoins

Hello Everyone

I Sell 10 Antminer L3+ of the 21-30 September Batch (PSU included).
If you live in Switzerland or somewhere around, you can also come by and pick it up.

This Batch was really expensive compared to later batches.
We therefore charge 5000 USD per piece.
If you contact me, we may be able to talk about the price.

We accept BTC, LTC, USD and maybe other cryptocurrencies as payment method.
Please let me know, if you need some kind of proof about the existence of these devices.
(For Example the invoice from Bitmain, Photos of the boxes when they arrive,...)

We can also talk through Skype, WhatsApp,...

 
Indeed!

And a strange thing...
Every single one seller its a brand New account and selling staff

they sold over 40,000 of D3 past few days, possibly more.  They added L3 back to stock a day later and it went out of stock a few times the past few days, they kept adding more back.

Anyone here with any updates on shipping for the first batch, please post anything you hear as it comes in. I'm sure many in this thread are as excited as I am.

In the meantime I figured we might as well run some numbers again to try to estimate Dash/X11 difficulty in December as a result of these D3's coming online. I know we have visited this topic in this thread already, so I will try to include the data from previous estimates.

I'd like to do three versions, the first being a worst case/pessimistic estimate, second a best case/optimistic estimate, and a third 'medium' estimate which is an average of the two together (roughly in the middle)

Please feel free anyone to check my math and correct me where I make mistakes as I'm sure I will.

Lets start with some quick general information for those who may be new here:

1 kH/s is 1,000 hashes per second (sometimes mistakenly written KH/s). 1 MH/s is1,000,000 hashes per second. 1 GH/s is 1,000,000,000 hashes per second. 1 TH/s is 1,000,000,000,000 hashes per second.
1 kH/s = 1000
1 MH/s = 1,000,000
1 GH/s = 1,000,000,000
1 TH/s = 1,000,000,000,000

Global hashrate at the time of this writing according to this link:
https://bitinfocharts.com/comparison/dash-hashrate.html

is 38.7 TH/s

Each D3 hashes (approximatley) at a rate of 15GH/s.
This correlates to 67 D3 units hashing equate to one TH/s addition to the global hashrate.
If we divide the current global hashrate by the hashrate of D3's, we see that it would take 2479 D3 units running to create that same global hashrate.

Another way to put it is if 2479 D3's were to come online right now the global hashrate would effectivley double.

Doubling the global hashrate would also double the difficulty and reduce profitability by half.

This of course does not take into account the other X11 coins that can be mined, and it would not be reasonable to expect all the D3's coming out to mine only dash, but for simplification I will only use dash for these calculations.

We have seen a total of 10 batches of D3's go on sale (that we know of) for delivery ranging from late September to Late November. As other have pointed out in this thread, by looking at the checkout page on the bitmain site we have been able to estimate in a rough way the amount of D3 units available in each batch. As Ross from CryptoCrane points out, we do not know how many of these units are actually paid for after checkout, but it stands to reason because of the high demand for these most people who are able to get thgouh the checkout process will follow through and send payment. (Also we will for the sake of this first 'worst case scenario' that the majority of units ordered are being paid for).

Based on the total number of units for each batch that we have collected in this thread previously, it is reasonable (and again a 'worst case scenario' in terms of difficulty) we could reasonably estimate that the average number of D3 units available across all 10 batches could be as high as 20k units per batch. Of course the data shows that the number of units available varies, with some batches having higher numbers and some being lower. 20k units I am asserting as a reasonable 'worst case' scenario average across all batches thus far that we know of.

There may have been several batches available on the Chinese version of the site that were not mentioned on social media, by my count however there have been 10 total batches for sure.


Now lets run some quick numbers on a profitability calculator here:
https://www.cryptocompare.com/mining/calculator/dash?HashingPower=15&HashingUnit=GH%2Fs&PowerConsumption=1200&CostPerkWh=0.21

I assuming an electrical rate of 21 cents per Kwh (again, being 'pessimistic')

At the time of this writing, one D3 would yeild $2,604 per month. (already WAY down from when these units were announced by bitmain, as many have mentioned here in this thread this number has been as high as $7k a month)
source:
https://www.cryptocompare.com/mining/calculator/dash?HashingPower=15&HashingUnit=GH%2Fs&PowerConsumption=1200&CostPerkWh=0.21

More quick math: If difficulty merely doubles, that comes out to $1300 a month.
If difficulty increases tenfold, thats $260 a month
If difficulty increases a hundredfold, it would cost more to run the miner in electricity than it would mine, and the D3 would operate at a net loss of over $178 per month.

Worst case scenario here, is that by December of this year 200,000 D3's come online, which would add 2985TH/s to current global hashrate. Adding that to the current global hashrate for dash of 38.7 TH/s we get 3023.7 TH/s, which would be an increase in hashrate of a multiplier of 78.13 (what I mean is, take the estimated global hashrate of 3023.7 and divide it by the current global hashrate of 38.7)

Based on this (worst case) scenario each D3 would mine 33.38 per month before the cost of electricity.

So this is my first estimate, which I call 'worst case' estimate for dash difficulty by December. Before I try to do a 'best case' what do you guys think of my math thus far? I'm sure I have overlooked things. Any and all thoughts are much appreciated.

On a quick side note, I was able to put in an order last night for 4 D3's on the bitmain site, but based on this math I don't think I will be sending the wire, and I'll just let the order expire.

Bitmain doesn't need to offload any weight. They have made a huge amount on selling the equipment on these and holding coins. I think they are want to reduce risk in holding btc/ltc so they are wanting to sell for USD or lower their risk.But they know they can survive for a long time. Maybe they want to outcompete others but Jihan is no fool. He would not sell equipment to ruin people intentionally. Otherwise this would be bad for his precious bitcoin.

it feels like they are trying to flood the market now and they are only accepting wire transfers. trying to get every bit of money while the mining rush is happening lol.

fucking corporations and their evil tactics

My first batch D3 is marked as "Shipping", but not yet as "Shipped" and I don't have the Fedex tracking number yet.

I saw that too. There was D3 on sale without any announcement today. Went to buy and saw it was bank transfer only! I hope they are not going to stop payments via BTC / LTC / DASH.

Try this:



Works pretty well, but you have to use it to get results.

I thought that DASH was a proof of stake coin? WTF? I would have been mining it a long time ago had I known.

That's interesting, I just went online to order a few, and it was BY WIRE ONLY, no option for BTC, or LTC, funny, because last week I ordered a PWR-Supply, and it was BTC only, go figure,

It's QUITE obvious that BITMAIN smells blood in the water and now ITS US-DOLLAR only, and they don't want no more BTC.

Crazy just 27 hours ago, you couldn't get a D3, now you can buy all you want, if you have US DOLLARS.

Goes to show that CHINESE buyers were only paying in BTC, and BITMAIN got smart, see's the writing on the wall. Time to go all cash, and all gold.

p.s. I'm an asian buyer in asia.

I gave you guys all details on how to buy from bitmain! Im not no reseller trying to eat off people here! I handed you guys the "KEYS" on how to secure a purchase from bitmain.. and now u ask me to "give you info" and say im cryptic?  really unbelievable members on here.. not a single thank you but criticism.

Shall i hold your hands to the washroom also?

" If it involves buying through you at a markup then no thanks. Not interested."
Thanks, read this thread and my post before you start acting up there buddy.  

Like i said! Fcking unblievable!

Unbelievable. You guys will just be wasting your time.. man u guys should read through this thread. Put that energy and effort into securing an order!

It is very unfortunate that their server(s?) are so weak. They don't even try to do this right.

But imagine if the shop was quick and fully functional during batch release. Those batches would fly out in a matter of seconds, not minutes and the problem would still remain: short supply and everybody angry because they didn't get one.

The only solution would be to limit the number of units per account, then limit the accounts per ip address logged in at the same time. And this would be much more fair than now. It takes more than luck to get one. I managed to get two miners this batch. But it took one hour, two computers and multiple browser windows to do it. I even had to tweak some of my network and browser settings to make it more resistant to slow servers.

so I guess, this is my first post and this confirms your theory

You definitely do not need to program your router. You connect to a VPN server through an encrypted connection, even if on public wifi. The server access the internet for you. But you are one of hundreds who use the same server, you're protected because no one can tell which person connected is accessing which site. Kind of like bitcoin tumbling, your data is hidden in the crowd. However, most VPN providers have IP addresses that are logged as a VPN. Basic website protections identify most VPN users.

 If you really want to spoof your location, rent a socks 5 that does not show up as a high risk IP.
