NEM's asset exchange isn't live yet and probably won't be until a few more weeks at least. And I wouldn't exactly call HZ a "popular" stock platform. It's a NXT clone and most NXT clones (e.g. FIMK, BURST) have asset exchanges which are hardly used. Qora has an asset exchange too although nobody uses it.

Also, BitShares has support for user-issued assets. Again, I don't think it's widely used. NXT is definitely the most popular one with XCP and MSC probably being the second and third most popular platforms, respectively.

Here is a list of guides for each platform in case you want to issue your own cryptosecurity:

It might be a good idea to wait a few more days or weeks so that the account reaches senior member status since it's already very close to becoming one. Senior member accounts tend to go for quite a bit more than full member accounts around here and a senior member account with green trust would probably be in quite high demand. Once the account's activity score reaches 240, it should become a senior member.

If there is a decompression, wouldn't the air pressure in the cabin compartment be greater than the air pressure in the cockpit? And since air tends to expand outwards, wouldn't that cause the cockpit door to slam shut (assuming that the cockpit door doesn't open into the cockpit).

EDIT: Nevermind. Looks like the door actually opens into the cockpit:




This is probably true.

So what are the odds of this not being a murder-suicide now? While the evidence gathered so far certainly points towards the co-pilot being the one at fault, could there be any other reasons that might explain why he was unresponsive and why he flew his plane into the ground?

Could it be possible that the co-pilot suffered a stroke or brain aneurysm which left him in a delusional state as he tried to land the plane? If so, then perhaps he mistook the captain for an intruder. Or perhaps he fell unconscious at the controls? Perhaps there was some sort of breach in the cockpit's windshield (e.g. a leak which would not have been detectable by the voice recorder) which caused a decompression incident in the cockpit which caused loss of consciousness and shut the cockpit door firmly closed?

Nice idea. Here's mine:

Would appreciate a quote thanks.

Wouldn't it be easy to circumvent the security mechanism though? If a steering wheel is locked using a chip or the electricity in a smart house is controlled by a chip, it would be pretty trivial to simply yank it out and replace it with another one.

Most computers these days come with a security chip that can prevent access to anyone who doesn't provide the right password. It's usually possible to reset the password by physically de-soldering this chip from the motherboard and replacing it with a new one. A door that only opens when you provide the correct password is another example of a physical good that restricts access via application of cryptographic principles. In such a case, someone without a password could simply smash the door down.

20 years? It's quite likely that the site would have been actually hacked or its owner would slip up and get caught by the feds during that time. 20 years is a long time when it comes to Bitcoin and computer security. Tor might not even be a reliable method of obscuring one's identity by then.

Also, it would have been easy to launder the stolen bitcoins if he had done it properly. He could have sent a portion of his stash through a mixer such as Bitmixer.io every couple of months and cashed out little bits at a time using LocalBitcoins. If the police becomes suspicious, he could have simply said that he was an early adopter which would be very difficult to disprove.

Any particular reason for this? Bittrex is an exchange which means that you don't actually have control over your private keys and they could get hacked anytime. While Blockchain.info is an online wallet, they are considerably more secure than other online wallet services out there since they don't have access to your private keys - thus making any bitcoins stored there truly "yours". Ideally, any significant amount of bitcoins should be stored in an offline rather than online wallet so your decision to not only use an online service to store the bulk of your savings but to also use an exchange such as Bittrex for this purpose is a rather strange one.

I was thinking of buying the Antminer S1 a while ago too (thread here). It's not the latest or most efficient miner out there but they are definitely very cheap. For example, here's one in my country that is selling for $40 NZD (about $30 USD):

http://www.trademe.co.nz/computers/other/auction-862628667.htm

According to this link, 180 GH/s should generate about 0.01356 BTC (worth $3.32 USD) per week or 0.05811 BTC (worth $14.23) per month.

The S1 becomes more efficient if you undervolt it. Then it will do 140 GH/s while only consuming 140 W. It should be quieter too.

If you have free electricity then the Antminer S1 undoubtedly the most profitable miner out there. However, if you pay for your electricity then the S1, while cheap to purchase, is probably not all that profitable since a newer miner such as the S5 can pump out four times the GH/s per watt compared to the S1.

This is true. If I already had the hardware, I wouldn't be asking this question.


This is really a hit and miss strategy. It could work, or it might not. Mining Dogecoin back in late 2013 before it hit any exchange would have been very profitable.


New Zealand. The only scrypt ASICs that I've seen around here are Gridseeds although I've seen some go for as low as $10-20 used.

I remember using a service called Indacoin a while ago which supported buying bitcoins using debit cards. The prices were a little on the high side but very similar to what I saw on LocalBitcoins. Mind you, this was over half a year ago so I'm not sure if they still have this option but I can't see anything on their site that would indicate that this has changed.

It's not easy for companies to accept debit cards for the buying of BTC since debit cards support chargebacks while BTC doesn't. A dishonest person could offer to buy BTC using a debit card and then once he got the BTC, initiate a chargeback that would leave the seller out of pocket. Hence the reason why companies that do offer it as an option tend to implement strict maximum purchase limits and proof of ID requirements.

I don't know about the others but I do have some experience with Freenet which I used back in the mid 2000s. You're right in saying that it's similar to Bitcoin. However, there is no real "blockchain" in Freenet. Instead, files are basically shredded up and it is these shreds that are distributed to different nodes in the network. No single node has ALL the files in the network but rather each file is stored across several different computers unlike the case of Bitcoin where an identical copy of the blockchain exists on every computer.

Another contemporary technology that inspired Bitcoin was BitTorrent and P2P file sharing networks in general (not only their decentralized data storage and file verification but also their "tit for tat" mechanism with rewarded those who contributed to the network).

I live in a place with free electricity. My original plan was to mine bitcoins using a used Antminer S1. However, I soon realized that the noise created would be too much.

Does anyone know if it would be profitable to mine altcoins such as Darkcoin with free electricity? The answer seems obvious but the problem is - I'm currently using a laptop from 2004 so I'll need to build my own dedicated mining rig.

What would be the best way to go about doing this? Could I simply buy an old Pentium 4 computer and stick a graphics card or two inside and mine profitably with free electricity? Or would I be better off buying a computer with a newer processor and attempting to mine CPU coins?

I posted a while back about how I was thinking of buying a miner or two. The miner that I was thinking of was the Antminer S1. However, after watching this video, I can see that it would be too loud for where I'm currently living.

A few questions:

1. Now I know that the Antminer S1 can be underclocked to 170W. Would this result in a quieter machine or would it still sound exactly the same?

2. Are newer generations of the Antminer S series any quieter?

3. Is there such thing as a quiet and powerful miner? I know that USB miners can mine completely silently but they aren't powerful enough to be profitable even with free electricity. Preferably, I would like something with either small fans (think of the fans that you'd find in a typical PC) or entirely passive cooling.

And before anyone says that mining isn't worth it. Well, I have free electricity.

If you want to be completely safe, then it's probably a good idea to assume that any online account accessed using that Windows PC is also compromised. Especially since you said that Malwarebytes was able to detect keyloggers. So you should change your passwords, security questions, etc. too if you haven't already done so.

Yes, it can send and receive bitcoins after you download the block headers. Compared to downloading the actual 30 gigabyte blockchain file, it only takes a few minutes to download the block headers so it's very fast. Another lightweight wallet that I'd recommend is Electrum which works in pretty much the same way.

You said in your other thread that your work computer running Windows had 484 threats and 23 infiltrations. That's actually probably a conservative estimate since malware scanners typically can't detect and remove everything especially in cases like yours where there are so many infections. Are you still doing anything Bitcoin-related on that computer? If so, then you really need to completely reformat the hard drive and do a fresh installation of Windows (actually you should probably do this even if you're not):


Generally speaking, Linux is impervious to malware so you should be safe as long as you don't visit phishing sites which can steal your bitcoins regardless of what OS you're using.

From reading his post history as well as this thread, I think it's likely that he's using Blockchain.info.

As others have already said, Liberia is probably too much of an extreme example. I can see how OP's idea might work better in less poor (but still poor) countries like Moldova and Ukraine though. Both countries have high literacy rates and reasonably well developed technology infrastructures and yet have low average costs of living and GDP per capitas of below $4,000 per year. $20-50 per hour would be quite a good wage for many people living in these countries.

From what I've seen and read, the pilot tried knocking and then kicking the door down for 8 minutes. I wonder why he didn't try to get others to join in - a la United Airlines 93? Granted, the doors leading up to the cockpits on modern planes are stronger nowadays due to new safety regulations passed since the 9/11 terrorist attacks but surely three or four people + a drink cart or fire extinguisher would have afforded a better chance of breaking the door down?

And really, anyone no matter what their job, age, wealth, or status can go crazy so the risk of these types of things happening cannot be entirely eliminated - only minimized. Having two pilots in the cockpit at all times makes sense. Think about it: If a typical pilot has a one percent chance of going berserk during a flight, then two pilots going berserk at the same time is one percent of one percent - i.e. 0.01 percent. That alone reduces the risk by a factor of 100 (although I suppose a truly motivated pilot could use social engineering to force or manipulate the other pilot into leaving the cockpit).

Is that spreadsheet still up to date though? I was paid for last week's posts but I never saw my name on that list. I can see that the last three members listed (fantoos, MadeinCoin, and juraj1303) have since removed the Bitin.io signature from their profiles. MadeinCoin who is second to last on that list joined on February 16 and juraj1303 who is third to last joined on February 12. fantoos seems to have deleted his enrollment post. Usually there would be a way to check the date of the last revision but the option seems to be greyed out. Nevertheless, the fact that there aren't any other usernames listed after those suggests to me that the list isn't quite up to date.
