How to use Bittrex?, i should to move my HMQ tokens to Bittrex?, why?
I dont understand that process.
That's basic knowledge you have to learn, you move your tokens to bittrex to trade if not you can just keep it to your wallet. It's already trading in bittex so anyone can buy and sell anytime they want, actually the price is still below ICO so it's good to buy now.

That cannot be right. It is above the ICO price i paid for. I have more than wat i put in definitely.

I miss the dump, someone sold his coin at 1200sat, what a crazy world, I don't understand why the price dump but for me it is a buying opportunity as more weak hands are shaken out

It just started and seems not that many participants yet.

hi, how can I transfer my humaniq coin to bittrex ?? please
You may withdraw to MEW using this instruction
https://docs.google.com/document/d/1EMD8RKnI0iTR1pa9OChKNS1wVJePQWS5opnhEKWOLLo/edit#
and from MEW to bittrex

Dear Humaniq Team,

I received my tokens fine but can the humaniq team at least edit the page https://blog.humaniq.co/how-to-set-up-an-ethereum-wallet-for-humaniq-tokens-2ba3cd18a5af  so that people actually know that the token address is this 0xcbcc0f036ed4788f63fc0fee32873d6a7487b908

This is a simple thing and i had to scroll back a few pages in this thread and also check the commends on that page to figure it out.
There are bound to be other people who are confused and who may have made mistakes. Thanks
867  Bitcoin / Hardware wallets / Re: What do u think of a tough keepkey/trezor/leger-nano-s ? on: May 10, 2017, 05:04:20 PM



I have not tried the newer Ledger Nano (the "S"), I was reasonably happy with the old Nano, but I felt it was not tough.

I had the same concern with my Trezor, it seemed to be not strongly built.

I have not used the KeepKey, it seemed too complex a product for a simple guy like me so I never bought one.

What I do like now is the Digital Bitbox, it DOES seem pretty tough, much more so than the two above ones I used for quite sometime.  It is a one piece (ex. for the recovery chip) made of tough epoxy.  I use it for cold storage.  Made in Switzerland.  Costs something like $50.

BitcoinNewsMagazine, you might want to get one and review it, I would certainly be interested in other people's views, here's their website:

https://digitalbitbox.com/


U kidding bro? That bitbox looks so flimsy that a small accident can snap it in two... and then u would worry about your word seed and hope u didnt lose that....



I took a look at Digital Bitbox back when it cost $120 and was not impressed. I think they dropped the price because it was not selling well. It is limited in comparison to Trezor and Ledger Nano S. Nano S are pretty tough here is a video of one being run over by a car and still works.

Wow nice
868  Bitcoin / Hardware wallets / Re: What do u think of a tough keepkey/trezor/leger-nano-s ? on: May 10, 2017, 04:53:26 PM
the key is taking a proper backup from your wallets so that in case you lost them or in case of some kind of hardware failure you won't be left without any recovery method of your funds. i believe the hardware wallets also have some sort of seed for this case but i may be wrong since i don't own one.

edit: apparently they do have a seed. so i was right
https://news.bitcoin.com/restore-hardware-wallet-seed-phrase/
https://en.bitcoin.it/wiki/Hardware_wallet

Agreed but it would be best if u have a tougher hardware wallet that maybe cost a couple of dollars more and also a 12-24 word seed. Still safer. It is kinda like how u put a casing on your mobile phone to prevent damage. I dont get why they shouldnt be a tough casing for keepkey/ledger/trezor.

Well, just my 2 cents.

Most people who buy a hardware wallet probably keep it in a safe or deposit box, but a "tough" version is not a bad idea.

Has any reviewer done a "drop test" to see how durable these devices are?
I would like to see one dropped down the stairs, frozen in a block of ice etc like they do with tablets/ smartphones.  Grin

That is exactly my point. It wont be a bad idea to just add some kinda casing to a hardware wallet to make it tougher. It does not have to be a totally new device.
Hey i am using Spigen slim armor for my phone and it works great.

A tough trezor would be great and especially if it came with a metal seed word keeper where you use stamped letters to lock in your seed.

Or maybe just a casing for it so everyone wont have to get a new one lol.
I wonder if Spigen or other casing manufacturers realize they can probably get a new segment by adding casings to this.

Trezor/Keepkey/Ledger nano should just approach mobile casing manufacturers to talk. A win-win situation imo.

Something like a toughbook instead of a notebook. So, in case an accident occurs, it isnt eaily broken. They have not made one yet it seems.

Or perhaps just buying 2-3 of those hardware wallets is better

The durability isn't really necessary in this particular scheme, given that you can use a recovery phrase to restore your account to any device. there is certainly value in an extra durable wallet, ESP given that these devices are somewhat fragile. With that being said, a barebone version of the same seems more efficient; making it moderately durable but easily replaceable would make people more apt to use wallet like physical tokens. As long as it has a screen and can be dropped from a decent height without shattering, it should be sufficient. Physical wallets should be a cold storage solutions, not used like a hot wallet.

I dont mean get a toughbook. I mean get a keepkey or a ledger wallet that is tough, not easily broken or damaged if drop...kinda like how a notebook is fragile and a toughbook is tough

Why? Even with .11 per kwh on my electricity there is still 7000 dollars profit every month with 20 rigs. That is after the subtraction of electricity of the rigs, electricity for cooling, insurance, water, internet, and of course rent. I really was just looking for some help in regards to infrastructure since I have already ascertained that it is profitable to mine.

Have u tested this or is this your assumption with online calculators??

I pay .17 per kw/h and still make a fair profit. Based on actual power usage and actual hash rates from the hardware I have mining right now  Smiley

20 rigs as in 20 x 6 gpu? 120 gpu?
872  Alternate cryptocurrencies / Mining (Altcoins) / Re: Advice on Mining Farm Buildout on: May 08, 2017, 05:55:48 AM
No there is a difference between algorithms when it comes to hashrate. I am mining Equihash and I get about 2700 h/s with 6x 1070's. You get 13.7 Th/s with the latest S9 Antminer but that does not mean the antminer is better or more profitable than the GPU rigs. I try to stay with GPU mining because of the ability to switch between coins and also because I generally do not like ASICS. All that happens when a new ASIC comes out is the early buyers make out and then the difficulty goes up so high that the later buyers generally struggle to ROI. GPU rigs can also be liquidated much easier should you ever need to. 

Yes but once this is in, litecoin mining is gameover for gpus and if it can be used for other coins, more gg
873  Alternate cryptocurrencies / Mining (Altcoins) / Re: Advice on Mining Farm Buildout on: May 07, 2017, 08:18:24 PM
Have you looked into renting space from a local colo? Won't have to worry about internet, cooling, insurance, security, etc.

Would the numbers for that make sense usually?

Btw, the antminer l3 https://shop.bitmain.com/productDetail.htm?pid=000201704270330299161GIIoSKl067B can do about 500mh hashrate for 800watts. This is for scrypt right?

An rx 480 is about 25mh for 140watts if i recall right.
That means only 150mh hash for 840watts

Gpu would nt be able to compete right?
Gpu and antminer l3 are for scrypr right?

U are talking about gpu mining and not bitcoin right
875  Alternate cryptocurrencies / Mining (Altcoins) / Re: Advice on Mining Farm Buildout on: May 07, 2017, 05:40:26 PM
I have actual hardware that is running right now of course and I keep a spreadsheet of payouts and fees for tax purposes. I know the power companies commercial rates so from there it is fairly trivial to calculate. Cooling costs are roughly 50% of the cost to run the miners depending on the time of year of course. Zcash is especially good to mine for the long term so I am just sticking with that for now.

I see. Yours is 0.11 + 0.055, around usd 0.165 cents cost to gpu mine and so far, is working out. Thanks for the info.

I am surprised cooling cost is so high.

Hi ppl.

Besides investment costs and electricity costs to calculate ROI, are there other costs?
Does the antminer S9 have substantial cooling costs?

The S9 antimer costs around 1089 USD, power supply at 105 USD.

I use cryptocompare calculator (link below) and it seems even at  USD 0.12 cents, that gives 169 USD per month profit.

https://www.cryptocompare.com/mining/calculator/btc?HashingPower=14&HashingUnit=TH%2Fs&PowerConsumption=1372&CostPerkWh=0.12

If minus pool fees, will get money back around say 10 months? Did i miss anything else.

My electricity costs would be around 0.09-0.12 usd cents, and i have to pay rent on a small place away from my home. Feasible, u guys think?
Comments appreciated.

I think one important point you are missing is that in power consumption for instance you will put 1125 watts for the 11.5 Th/s S9 machine but you should also take into account the watts you will consume to cool the environment you put the machines in.

So roughly I think (not sure though) 50% extra watts should be added to total power consumption and than calculate the stuff.

Hope this helps.  Smiley



Are u sure it can cost 50% more to cool it down. I have not seen such posts anywhere.
The fan on antminer should be sufficient yes?

and how are you cooling your gear?  A/C or fans?

The room temp has a lot of meaning.  ie an s-9 in the tropics needs more effort and money to cool then an s-9 in Norway.

Also everyone has left out that the gear breaks often.

  1 in 10 chance of a break down

1 in 10 chance is not so bad i guess. My area is around 28 degrees room temperature.

If you are willing to wait for a more reasonable amount of time, then IOTA will surely reach over $1billion market cap (currently on about $60M)

Features:
- zero fess
- no miners
- massively scalable (the network works better the more it is used)
- nano transactions
- billion dollar companies on board
- confirmations in seconds once network grows
- designed to the the backbone of the Internet of Things (a trillion dollar industry in the years to come)




Pls name those billion dollar companies and link them. I cant find them anywhere

Also those calculators take into account difficulty already?
But are they accurate?
