I keep getting the following message despite not having logged into my account in ages:

Quote
Unverified account withdraw limit has been reached. Please try again in 24 hours. To increase your limits, please verify your account. See this link for more details.

What's the new withdrawal limit for unverified accounts? I remember it was something like 1 BTC a few months back.

EDIT: Hmm... According to their support page, it looks like it's 0 BTC. Obviously this is far too low. Looks like I'll have to go through their verification process. :/

EDIT 2: Got a "No public record match" after attempting basic verification:

Quote
We could not match your information to our public record providers. To complete the verification process, you must apply for an enhanced account.

The enhanced verification withdrawal limit of 100 BTC per day is overkill for me IMO since I don't need to withdraw that much. Oh well, here it goes...

I didn't said JD isn't trustworthy....i said that you never ever must send your private key to a website. It is the same as giving away your PIN of your bankaccount.

Perhaps, but if you have hundreds of bank accounts at your disposal and you have an empty bank account which you don't intend to keep more than several dollars worth of BTC in then what's the harm in exposing that bank account's PIN?

Let me rephrase that: Its unnecessarily complicated and risky to use brainwallet when signing(!) a message. Just use your client/service.

Now that I agree with, especially since most people would need to open their client to obtain their private key anyway. I guess they could use a brainwallet passphrase or something like Vanitygen instead to generate private keys but even so, they would still need to fire up their client to make transactions.

using c-cex
So here is what you need to do, download a wallet

https://bitcoin.org/en/choose-your-wallet

Then withdraw your coins coins for C-cex to the receiving address in your wallet.

Then use the sign message option in the wallet.

This would be the best approach to take if OP just wants to prove that he controls the coins in that address. On the other hand, if OP wants to prove that he owns the actual address in question (e.g. perhaps he is the owner of an account linked to that address which has since been compromised and he needs to prove that it's actually him) then it wouldn't work. His only option then would be to ask C-CEX for the private key and I seriously doubt they would grant such a request.
4  Other / Beginners & Help / Re: signing a message on bitcoin address on: June 22, 2015, 01:25:51 PM

That only works if you have the private key for the address, which most exchanges won't give you. What exchange are you using OP?

It also requires you to give the private key to someone else, which is a bad idea.

You're not giving the private key to someone else. The code is open source and it's all client-side JS. It's probably safe, but if you want to be even more sure that the website hasn't been tampered with, you can download the script yourself and run it locally using an offline computer.

i would suggest to use electrum to sign a msg is pretty easy to do with their user interface try out...

This is a good idea, although it would depend on why you need to sign a message from an address in the first place. The deposit address that C-CEX gives you isn't yours because it belongs to and is controlled by them. And you can't use it to sign a message since you can't sign a message from an address that you don't control.

Why do you want to sign a message OP? Is it to prove that you have control of the coins in that address? If so, then it would probably be best to transfer the coins on the exchange over to an Electrum address and sign a message from that instead.

There are only two living people now who were born in the 19th century - both of whom were born in 1899. Just two years ago, that number was six. It's likely that there will be nobody born in the 19th century who is still living in a year or two from now. Sad

Surely it's just a genetic lottery win? Humans certainly aren't designed to live that long and people with perfectly respectable lifestyles drop dead in their 50s and 60s every day.

I am not sure whether the secret for longevity lies in the genes or in the lifestyle. But you can't say that humans aren't designed to live that long. There are references from 400 or 500 year ago, about people living up to 100 year or more. As the living standards increase, along with the advancement in the medical science, longevity will increase further.
There are some physiological limits. Approximated limit of average lifespan is about 250 years. If we solve genetic issues then there still would be another limitation due to nature of our brain. To be exact, there is no possibility to remember more than 4000-5000 years of living experience. You won't die but you'll forget anything what happened before last 4000-5000 years of your hypothetically unlimited life. And there will be no way to recover these memories.

Where did you get that number from? Even with huge advances in medical technology and a significantly larger population, the maximum lifespan of humans seems to have a hard limit of about 120 years - not 250. The oldest people today aren't significantly older than the oldest people who lived 100, 200, or 300 years ago even though far more people are now reaching old age than previously. Jeanne Calment was the only person to live past 120 years and she was definitely an outlier.

I also heard that number. It is thought that 250 years is the potential longevity of the brain, that is, how long humans would live if their bodies didn't deteriorate with age. Though it is nothing more than speculation of course

A cure for all cancers (ignoring the fact that cancer is a collection of diseases with a myriad of causes far too complex to have a single cure) would increase the average lifespan by approximately 10 years. Curing heart disease would probably increase it by another 10 years. But even with the average lifespan at close to 100, I would still expect the oldest humans living in such a world to be no older than 120 years old.

I read that the total elimination of all forms of cancer would only add up 3 to 4 years to the average lifespan. On the hand, the naked mole-rat, the only mammal which doesn't suffer from cancer at all due to its very special immune system, lives up to amazing 30 years (given that rats live only a few years)...

Hmm... You're right. I remembered seeing that 10 years figure on a blog/forum somewhere and never bothered to check it. It seems that curing cancer would only increase the average lifespan by slightly over three years while a cure for cardiovascular disease would increase it by just under seven years.

I wonder if curing both at the same time would yield a far better result, however. The reason why a cure for cancer only results in a three year increase in life expectancy is because of Taeuber's Paradox which states that those who would have died from cancer but didn't would have died from cardiovascular disease or some other age-related condition shortly afterwards anyway (and vice versa).

Yup... there are two of them. Susannah Mushatt Jones (b. 6 July 1899) from the United States and Emma Morano (b. 29 November 1899) from Italy. The former will be 116 years old, in two weeks from now.

One interesting fact which I have noticed is that 20 out of the 45 oldest living people (as of now) are from Japan. What is the secret behind their longevity? Organic food? or better medical care?

According to this article, it's likely to be a mix of different factors at play - including food and medical care:

http://www.agewatch.org.uk/secrets-of-longevity/japanese-longevity/

Quote from another article which gives pretty much the same reasons as above:

Quote from: Daily Express
The secret of that longevity is a traditional diet of fish, rice and simmered vegetables, easy access to healthcare and a comparatively high standard of living in old age.

Link: http://www.express.co.uk/news/world/407445/What-is-the-Japanese-secret-of-living-to-100

Also notice how virtually all of those who live past 110 are thin. Japan happens to be the thinnest country in the developed world and calorie restriction (with optimal nutrition) has been proven to extend lifespan across a range of different species so perhaps there is a link somewhere there as well.

Chart showing the percentage of obese people in 34 developed countries:



People with obesity have a much greater risk of developing cancer, cardiovascular disease, stroke, and diabetes which probably affects the average life expectancy quite a bit in countries where obesity is more common. According to this link, Japan has an average BMI of 22.5 while the United States' average is 26-29 (depending on what source you're using). Another study shows that BMI and life expectancy has a very strong correlation.

true, and all of these risks can be minimized with transparency; if the site shows their bankroll at all times as well as proof of funds, investors can see for themselves weather or not the site's investment system is legitimate or not. i believe the lack of this transparency was why dadice decided to halt their investment option as well

Dicebitco.in offered exactly that but it still ended up making its investors lose money. It offered proof of funds and the size of the bankroll was always shown on the upper left corner of the site:

I would reduce the deforestation and help people get more practical education especially in poor and violent areas where kids are forced to take jobs because they don't get proper education, practical education in the sense making them learn about Cryptcurrency and Bitcoins, getting them hands-on internship etc, I think education for knowledge to earn money is way out of poverty which is one of the black-mark in our society, would love to get your opinions and thoughts on how you would impact the world when you are a billionaire.

I have some knowledge and training in biochemistry so I'd probably open my own lab and conduct scientific experiments. Having a billion dollars or even a few million dollars would free me from having to submit grant proposals and relieve me of any teaching responsibilities that usually come with becoming a researcher at a college or university.

If anything good comes out of my research, I'd probably put it into the public domain just like the way Jonas Salk did with his polio vaccine.
10  Other / Meta / Re: ##Admin Please Pay Heed ## on: June 22, 2015, 08:21:37 AM
i dont know if i am correct but till now i have seen that most of signature camp pays only for the posts in Gambling sections, or they encourage that, why so?
i think its not good.
Admins should consider this situations. Tongue

Only those signatures that advertise gambling sites encourage posts in the gambling section.

Your signature is that of a gambling site (777coin) so it makes sense to encourage members who are displaying it to post more often in the gambling section. Someone who is browsing and posting in the gambling section is more likely to click on your signature and play at 777coin vs. someone who is browsing and posting in the development & technical discussion section or the politics & society section, for example.

My signature is that of an altcoin exchange, so there is no such encouragement. Only those posts in the off-topic section are not counted. The Bitmixer campaign discourages its members from posting in the alternate cryptocurrencies section by not counting these posts since they don't deal with altcoins (whereas mine does).

Which signature campaigns pay for only those posts made in the gambling section? I'm not aware of any that do this although I've seen a few that either have a higher rate for posts made there (such as yours) or enforce a minimum number of posts to be made in that section per payment cycle (e.g. CoinRoyale). In any case, I'm sure it's far from common.
11  Economy / Service Discussion / Re: Is this user cheating coinomat ? on: June 22, 2015, 08:00:30 AM
Coinomat is using the bot hosted by marcotheminer so this bug probably isn't unique to their campaign. The bot shouldn't be counting spaces over two characters in length. Unless the bot is customizable so that Coinomat can choose unique strings of characters to ignore (a quick look at the bot's official thread here suggests that no such feature exists but I could be wrong), it's probably best to contact marcotheminer directly via a PM and ask him to update his bot or submit a feature request on his thread:

on this forum, you have two options for joining signature campaigns.
better option: go HERE choose a signature campaign that accepts newbie rank and join it by following its instructions. after a while your rank goes up and you earn more by posting.

other option: buy an account with your bitcoins to be able to join better campaigns and earn more.
be careful not to get scammed.

and always follow the rules and be careful!

None of the signature programs for newbies are really worth it, in my opinion. The highest paying one is the 64blocks one which pays 0.00005 BTC per post with a maximum of 50 posts per week. A very prolific poster might reach this limit and make 0.00005*50 BTC which equals 0.0025 BTC. Yet that amount of BTC is only worth 60 cents.

If someone decides to join a signature campaign as a newbie, they shouldn't view it as a serious way to earn BTC. Instead, they should think of it as an educational experience similar to faucets. After all, the amounts involved are pretty much the same.

Anyway OP, if you're still interested in mining with your computer then you could try mining altcoins and converting these to bitcoins using an altcoin exchange like Cryptsy. There are many altcoins out there which can still be mined using CPUs or GPUs. The only ones which have ASICs built for them are SHA-256 based coins like Bitcoin and Peercoin, and scrypt-based coins like Litecoin and Dogecoin.

Agree. In most country, the electricity cost will never make you profit mining Bitcoin. However, mining altcoin might give you a little profit. Well, most altcoin difficulty is lower compared to Bitcoin. Also, instead of mining by yourself, joining a pool might speed it up. If you intend to mine Altcoin and join a pool.. Choose a pool which will automatically mine profitable altcoin and exchange it into Bitcoin for you.

It's not because of electricity costs that mining Bitcoin using general purpose hardware is a bad idea. It's because of ASICs. A single ASIC is equivalent to an entire warehouse full of computers. If a coin has ASICs developed for it, then these ASICs are competing with your single computer for the same block reward and because of this, your single computer always inevitably loses. Even tiny SHA-256 coins like Betacoin and Terracoin can't really be mined using CPUs or GPUs anymore in any reasonable sense because the existence of a single ASIC mining on the network is enough to outclass hundreds of CPU and GPU miners.

one question  what does your power cost?


and a suggestion read my thread.


https://bitcointalk.org/index.php?topic=1086011.0


these usb sticks will be the cheapest way to mine.

most likely you will lose money.

but if you want to get started 1 of these sticks is about 20-25 usd and will be available  sometime this summer.



Although cheap, that's not actually the cheapest way to mine.

The cheapest way to mine would be to head over to eBay and buy something like a Block Erupter/Ice Fury/Antminer U-series or any other obsolete stick miner for $5 and mine with that. It wouldn't be profitable of course and you might not be able to reach the pool's minimum payout threshold (you could always opt to solo mine instead however) but at least you would still get the full mining experience, if that's what you're after.

Anyway OP, if you're still interested in mining with your computer then you could try mining altcoins and converting these to bitcoins using an altcoin exchange like Cryptsy. There are many altcoins out there which can still be mined using CPUs or GPUs.

Here is a list of CPU-mineable coins:

http://www.cpucoinlist.com/

(Note: It hasn't been updated in a while though so some coins might have transitioned over to GPU mining since the list was written. To the best of my knowledge, no ASICs have been developed for any other algorithm besides SHA-256 or scrypt however.)
15  Bitcoin / Bitcoin Discussion / Re: I am pretty confident we are the new wealthy elite, gentlemen. on: June 22, 2015, 06:11:23 AM
Tell that to the guys who purchsed Bitcoin when the exchange rate was going at $1,200 per coin. Bitcoin has lost 80% of its value, from its peak, which was reached in December 2013. No fiat currency has suffered such a crash. The worst performing fiat currency is the Ukrainian Hryvnia, which has seen its value dropping by 60%.

*ahem* Deutchmark under the Weimar republic. Venezuelan dollar in 2005. Zimbabwean dollar around the same time... I can come up with others. Where BTC did better, is that it did bounce back.

I was talking about the situation since 2013. Out of the 200 or so different fiat currencies (plus BTC) in existence, Bitcoin is the worst performing currency against the US Dollar since December 2013. Historically, currencies such as the Deutchmark and the Venezuelan dollar have suffered even worse crashes. But they occurred years, if not decades ago.

When measured in terms of implied value against the US dollar rather than the artificial "official" value, the Venezuelan bolivar has actually performed worse (60 VEF to 1 USD on December 2013 to 430 VEF to 1 USD on May 2015):

After reading this, the scale of black market and digital economies and the effect Bitcoin will have on them I am pretty certain we are going to be very wealthy men -- even with a sum as small as 10 Bitcoins. It's just so hard to believe. We are only in the beginning storms with these significant rallies from 10 to 20 dollars. I will not be surprised to see prices from hundreds to thousands in the coming months.

The world just isn't going to be the same and we have been blessed as the pioneers.

In the article, he predicts that the value of Bitcoin will explode tremendously in the next three years (a prediction which later turned out to be mostly correct) and also recommends putting nearly all of your assets into BTC.
16  Bitcoin / Bitcoin Discussion / Re: Bitcoin Executive Says 21 Million Cap Increase Inevitable on: June 22, 2015, 05:34:52 AM
He was being sarcastic...?  Is Jon Matonis against the hard fork?  If he is, he's trying to say Gavin's move is a precursor to a shit storm coming in BTC land.

If XT succeeds, increasing the 21m cap would not seem farfetched.  At least in his eyes.

Would someone who was once the Director of the Bitcoin Foundation really think that the two are even remotely comparable? Because the differences between the two proposals are enormous. Satoshi always intended for the block size limit to be increased at some point in the future. That was always part of Bitcoin's design and it was never a question of "if" but "when". That the majority of miners would someday support a hard fork that aims to increase the max block size is to be expected:

Quote from: satoshi
The bandwidth might not be as prohibitive as you think. A typical transaction would be about 400 bytes (ECC is nicely compact). Each transaction has to be broadcast twice, so lets say 1KB per transaction. Visa processed 37 billion transactions in FY2008, or an average of 100 million transactions per day. That many transactions would take 100GB of bandwidth, or the size of 12 DVD or 2 HD quality movies, or about $18 worth of bandwidth at current prices.

Link: http://www.mail-archive.com/cryptography@metzdowd.com/msg09964.html

Arbitrarily increasing the total number of coins changes a fundamental aspect of what Bitcoin is and Satoshi's comments make it clear that such a thing would be very undesirable. Even if there is no centralized party trying to enforce a fork, I find it unlikely that miners would accept the latter or even equate the two proposals as being anything remotely similar.

How, exactly, would such a change roll out? There is actually no point in the code (that I could find) that specifically imposes such a cap. The only thing that this cap comes from is the method which the block reward comes from, simply dividing by two. There is a point where the rounding used in the code simply returned zero, and that was when the block reward went to zero. This just so happens to be just under 21 million Bitcoin, which is likely just a coincidence, not a specifically hard coded thing.

It would be a hard fork that involves a change in the coin emission algorithm. You're correct that there is nowhere in the code that specifically calls for a max cap of 21 million coins. However, this number can be deduced by looking at the emission rate (50 BTC blocks every 10 minutes with a halving every ~4 years). Changing the specifics of the emission algorithm would change the maximum number of coins but to do so would require a hard fork.

Acceptance of the hard fork can be measured by looking at the proportion of miners who switch to the new chain. Most likely the chain would bifurcate since any proposal to change the maximum number of coins would be very controversial (to put it lightly), and you would have two chains on either side that exist independently of the other.

Sorry for bumping, but needs to be said.

Just-Dice is a fairly trustworthy site. More importantly, I made sure to withdraw coins from the address before entering my private key.

18  Alternate cryptocurrencies / Mining (Altcoins) / Re: Any Hard drive mining based coins runnable through Raspberry pi? on: June 22, 2015, 04:39:39 AM
It is very cheap but there are some differences between that PC and the usual PCs that you might see on a store shelf. For example, it doesn't use a normal OEM version of Windows 8.1 but rather, it uses something called "Windows 8.1 with Bing". According to ZDNet, prices for this version are probably close to zero for OEMs (link). It also has a few minor restrictions compared to the normal version of Windows 8.1 and is supported by their Bing search engine.

Secondly, while the processor is an Intel, it is an Atom which is typically found in tablets and mini PCs and runs at a low clock speed (1.33 GHz). Its performance is similar to a high-end Pentium D from nine years ago although obviously it's far more energy efficient.

You can usually find brand-name tablets with Atom processors and running Windows 8.1 at around the same price point as well. For example, there is the HP Stream 7 at $99.99 and the Toshiba Encore Mini at $84.99. If you cracked one of these open, you would probably notice that their internals are very similar.

I'm not very familiar with hard drive mining coins but I know that with BURST, it's usually recommended to go with USB 3.0 if your hard drive is large (i.e. over 1 TB). I went over the specs of the mini PC posted by the OP but couldn't find any mention of whether the USB ports are 2.0 or 3.0.

in the old days everybody HAS TO run a full node, so it is logical that there were thousands of them! just keep that in mind. of course today everybody runs a lite client.

I don't think that's entirely true. While the mainstream bitcoin client that's know known as bitcoin core was and still is the most trusted wallet, alternatives existed even from the early days. Not everyone that wanted to use bitcoin needed to run a full node even in the old days.


It also depends on what is meant by "old days". For example, I first got into Bitcoin back in mid-2011 and back then, there were no lightweight wallet options that I was aware of. I remember trying to sync the blockchain over my crappy college Internet and giving up because it took too long. Perhaps if there were lightweight wallets back then, I would have paid more attention to Bitcoin and its future potential. Sad

Both Electrum and MultiBit are the most popular lightweight wallets for PC right now and both were released in late 2011. Same with Blockchain.info which is currently the most popular online wallet. That one was released in August 2011. Mycelium's mobile wallet was released in late 2013.

So I know that bitnodes has been monitoring the network for quite some time, however their website only displays data from the last 365 days. Any way to look at older data?

I know it's been discovered that the old stats weren't valid but if you're still interested in seeing what the site looked like back in 2013, you could try browsing the archives at the Internet Wayback Machine:

http://web.archive.org/web/*/http://getaddr.bitnodes.io/

The earliest snapshot is from June 2013 and shows that there were 470,000 nodes at the time (again, this was from back when the stats weren't valid):

http://web.archive.org/web/20130609095243/http://getaddr.bitnodes.io/

If Bitnodes only started showing accurate stats from late December 2013 onwards, then this snapshot from February 2014 is probably the earliest accurate one:
