101  Other / Off-topic / Re: Complete the sentence... "I would sell all my Bitcoins if..." on: May 15, 2015, 06:25:26 PM
If history is any guide and assuming that you're in it for the profit, then it only really makes sense to sell when the price shoots up suddenly since it's almost guaranteed that it will come crashing down pretty soon afterwards. You'd have to be pretty quick though since ATHs rarely last more than a few hours to days at most.

I would prefer to sell if it is giving me best returns on my investment whatever prices it reaches but if i am getting better on whatever i have invested and i am earning more then i would definitely prefer to sell irrespective of the value and i will not keep on waiting to reach it $1000.

I think i would sell if it is reaching  $2000 and then would definitely sell and earn so profits as i am here to earn money so it doesnt make me so loyal to say that i will never sell my bitcoins and yes if i am earning good  i  really dont care about the future of bitcoins i would definitely sell.

But Bitcoin was supposed to be much more than that...

Satoshi would be so ashamed to see what our community has turned into. Cry

Just kidding! I suppose most people are in it for the money nowadays. Heck, if Bitcoin was restricted to ideological types then it would be nowhere near as successful as it is today. Cheesy

Hello , Coinbase problem is the verification that take on funding option sometimes you will
need to send some money to your account via Bank , but they will take a lot of time to
confirm it , at that time you may loose if you buy or the market can made changes .

Bitcoin Boy .

I admit I've never used Coinbase before but with day trading, I would think that your balance (both fiat and USD) would already be stored in the exchange itself with buy and sell orders being placed seconds after submitting them. So after the verification process and initial deposit, you would rarely need to send fiat to the exchange from your bank account, no?

I've been running Faucets for years, and I would not have been doing that unless they made profit !

Most of what has been said above is pretty accurate regarding how the faucet makes money.

  • Advertising
  • Captcha's
  • Re using your traffic
  • Donations

I don't use captcha's to generate income, or donations, but I do make money from advertising, and re selling my traffic.

My outgoings for the two fauctets I currently have is around 2.5BTC per mth but I aim to make what ever I spend x2,

Just out of curiosity but why don't you use captchas to generate income? Is it because you specifically choose not to or because their reward is too low for it to be worthwhile? I know Solve Media gives you a small reward for each successfully solved captcha and I haven't heard any complaints about their captchas being easily beaten by bots.

Donations, I can pretty much understand though.

When I started Bitcoingenie.info I used solvemedia on that one and to be honest for what they pay, and there min amount to payout which I think is currently $200 and the fact I'm in the UK just didn't make it worth while, plus the fact it is pretty easy to defeat with a bot, I mean there captcha is either "very nice" crocodile tears" or "pajama bottoms" they don't revolve the captcha enough, plus I don't like the way they have started the out of screen thing when you click the reveal.

Its all about keeping your users happy, I'm fortunate enough to have an adsense account, in fact I logged into adsense yesterday and apparently it was my 9th year anniversary of using adsense lol

And yeah donations are just a dumb ass way of trying to make money from a faucet.... if people need the dust to start with they are hardly likely to chuck a BTC at you are they lol Wink



Thanks for the answer.

I didn't realize Solve Media had so many issues. Would you say ReCaptcha is the best captcha then? (especially in regards to resistance to bots)

And donations were probably more of a factor back when there were fewer faucets and most of them weren't solely motivated by profit. I believe Gavin's original faucet subsisted solely through donations for most of it's existence.
104  Bitcoin / Bitcoin Discussion / Re: What should the government do to make women start using Bitcoin? on: May 15, 2015, 03:28:13 PM
Government should start a workshop on creating the awareness level of bitcoins to the society and womens should be invited for free without charging anything from them as the womens are the best when it comes to shopping so they must be motivated to use bitcoin as more as possible.

I think government should ban fiat currency and the usage of credit cards that will make women to attract towards bitcoin and that will make bitcoin community more richer one as womens population is atleast 40% across the globe so if they get into bitcoins then it can be a profitable venture.

they can't ban their own currency, it would be stupid for them... women will eventually follow adoption, when it become more wider it will come naturally, you can't force them for sure

but besides this, what about transgender and other category like that? does they also need to use bitcoin

Those who identify as transgender will probably have the same needs and requirements as those whose gender identity corresponds to the sex they were born with.

Yup that's true women should start using adoption of bitcoin that will make bitcoin more popular and I believe the users of bitcoin should introduce it to their friends and family so that they are aware about the bitcoin and start using it as mode of payment.

Even if you introduce it to women, there will be only a little that want to know about this because woman like things to be practical and easy and everything that could be used to buy with bitcoin can be buy with fiat as well so I dont think that woman will take this seriously especially it is not easy for some woman to operate technology thing like opening wallet and such

Sounds like a temporary problem then. Using Bitcoin today is much easier than using Bitcoin in 2013 which was much easier than using Bitcoin in 2012 which was much easier than using Bitcoin in 2011 which was... You get the idea. There will be more and more tech startups competing for the opportunity to bring cryptocurrency to the masses. I don't see why this trend won't continue. There are already several cryptocurrency-related services out there (e.g. GEMZ) which are aimed at women more so than men.
105  Other / Meta / Re: Imposter Warning for Newbies! (thank you) on: May 15, 2015, 01:45:06 PM
I think it would also be a decent idea to somehow highlight newbies who post in the Marketplace section. Since the newbie PM warning has come into effect, I've seen a few threads where newbies are trying to publicly scam potential buyers. I don't think anyone has been scammed yet, but there have been a few close calls.

Ex: https://bitcointalk.org/index.php?topic=1023218.msg11312057#msg11312057 and https://bitcointalk.org/index.php?topic=1049386.msg11376537#msg11376537

Maybe if their rank was highlighted red, or there was a message under their name saying "Warning: this user is a newbie!" that would prevent some of these public scam attempts. What do you guys think about this idea?

Edit: I did an inspect element with my idea, I was thinking it could look something like this:


I edited your picture to make it more representative of what you might actually see since that newbie already has red trust and a signature and personal message that says "Sr. Member" (huh?):



Personally, it feels a little bit redundant but I can see how highlighting the rank could be useful. In any case, using escrow is recommended when you're dealing with other members regardless of whether they are newbies, junior members, full members, etc.
106  Bitcoin / Bitcoin Discussion / Re: Chinese team released software to mine Satoshi's coin on: May 15, 2015, 12:44:29 PM
Wasn't there someone on the forums here who tried doing something like this? He was paying people to run a piece of software that would try to crack BTC addresses. I'll see if I can find that thread...

EDIT: Found it:

http://bitcointalk.org/index.php?topic=929196

I wonder what would happen if it was discovered that addresses could be stolen in this manner? Probably some kind of emergency hard fork would have to be done before the damage has a chance to spread. There would need to be a rollback of any transactions too.

According to the guy that released the software, he claimed that they had cracked two addresses but refuse to specify, saying it would destroy the integrity of bitcoin.
They also said they had found 38,187 addresses that belong to Satoshi, or 50*38187=1,909,350 btc.

It would be easy to provide a proof. My chinese has weakened over the last years, did they provide the txid of the stolen coins to confirm this on the blockchain?
There is no way they brute forced two different addresses, I am with AGD on this they can prove it easily if they did and I want proof before we even begin to believe anything. The only way they have hacked private keys are through either attacking the pc the wallet is on or weak brain wallets.

Or a weak RNG.

We all know that Chinese aren't that far behind in terms of technology. In fact, theirs are advancing at a fast rate. Even though they hold the sufficient technology to crack or generate the same private keys to Satoshi's addresses, it still is a resource-consuming and time-consuming effort to recover those coins. SHA-256 is secure enough to be cracked by our technology for the next couple of centuries, and I doubt that even with the world's most advanced computers today, the algorithm would be cracked within a short span of time.

"Far behind"? !!!

LOL!
They are way ahead of everyone.
The truth is, you should consider yourselves lucky to say that YOU are not far behind the Chinese in technology.


i remember that japan were the one that were so far ahead in general technology, chinese are just good at doing thing fast and discover new things maybe, because they are many, still this news remain a pure trolling

Japan went from literally nothing to being a major superpower not only once but twice during it's history. It's possible that China could do the same.

Amateur hour is over.
Let's go over how a public address is derived from a private key:

1. SECP256K1(Private Key) ---> Public Key
2. RIPEMD160(SHA256(Public Key)) ---> Public Address

So these script monkeys are telling us that they found an ancient Chinese secret that can crack two hashing algorithms and an ECDSA all at once?

Unless Satoshi used a weak random number generator for his private key, and these amateur happen to know his public keys, GLHF faggots.

I don't think it's possible to deduce a private key from a public key. It does weaken the security since it strips away an additional layer of encryption but not to the point where an address could be compromised.

I'm surprised that an altcoin hasn't yet been released to do this very thing.
Still, even if the key was somehow found, I agree with others that this would amount to theft rather than once or twice in the lifetime of the universe luck.

An altcoin? How does that help in anything?

An altcoin that rewards those who submit shares to a decentralized effort to crack Satoshi's wallets? That doesn't sound all that different from what Primecoin/Riecoin/Curecoin/Gridcoin/Foldingcoin are doing so it might just be possible.

It would be completely pointless though for reasons that have already been mentioned many times in this thread.

Wouldn't trust it it's probably a virus.

Wouldn't trust it it's probably a virus.

It makes sense, I also think it's a virus, because normal people know the probability of hacking satoshi's addresses, sane people won't believe they are really hack, because they couldn't find the keys until the universe is destroyed. Grin

I have stated the probability before, we need 10^70 years to crack the keys. LMAO. It's an impossible crack, if they can crack them, all exchanges' wallets are also dangerous, bitcoin system will be destroyed too, bitcoin won't be worth 1 usd if satoshi's addresses are hacked.

Even on that pages comments, in chinese, everyone just tears apart the post as a hoax and the software as a trojan or malware or other incentive driven fake. The first comment on the page is longer than the page article itself going into 8 reasons why its fake.  I can't believe some of you are even entertaining this discussion, if you didn't immediately realize what this was you need to restudy what bitcoin is and how it achieves what it does.

If the software is available for public download then it should be easy to confirm whether or not it's a virus.
107  Bitcoin / Hardware / Re: Avalon Nano - Stick Mining Fun! on: May 15, 2015, 11:46:00 AM
You can run much the same calculations for the Avalon Nano.  Rather than going forward into unknowns you can use historical data.  E.g. say you got one when it first came out and started hashing with it 24/7 until today; http://retrocalc.net/ -> ~BTC0.0117. (iMiner from its introduction: BTC0.0053)
They're both not particularly weighty miners - no StickMiner is.  For something more powerful but without breaking the bank, I think you'd have to take one step up to PodMiners - like the Antminer U3, Gridseed Orb/Mini/Infinity/Whatsinaname or Avalon Mini.

So instead I judge them on their own merits.  iMiner is very small and contained, NanoFury 1 is open source, and the Avalon Nano is nice and tidy but still provides reasonably easy access to components for tinkering and is easily sourced Smiley

Nicely explained.

I tend to agree with the idea that different miners have different qualities which may or may not be important depending on what it is you're after.

Didn't know there was a thing called "pod miners". I always wondered what that form factor was called. Cheesy

That being said, if you consider that getting a payout from a pool is part of the experience of mining, then it might be a little bit disappointing if a miner never reached this limit. But it's not a huge deal personally and I'd much rather solo mine with stick miners anyway. Grin
108  Economy / Micro Earnings / Re: How faucets make money? on: May 15, 2015, 09:08:41 AM
To create an adsense account you need a site rich in context. Then, however, you can add the adsense to the sites not so rich in context - it is said so in rules.
I have other pages than faucet, that have a lot of text and generaly a bit of "quality" users. Then, a faucet which generates much more traffic, but low quality

Ah, OK thanks for the explanation. I always assumed the requirement was universal. Never thought that as long as at least one of your sites have good content, you can place the ad even on pages/sites which lack high-quality content. I see that Freebitco.in also has AdSense ads and they're the largest faucet in the world so I guess that pretty much validates it then. Smiley
109  Economy / Trading Discussion / Re: Is day trading on Coinbase profitable? on: May 15, 2015, 08:58:35 AM
So leverage basically makes your profit and loss increase faster than it would without leverage?

exactly, its a good tool to use.

What leverage does is it amplifies risk and reward. You stand to gain much more with leverage but you also stand to lose much more as well. With 10x leverage and $1,000, your effective trading position would be $10,000. Because of this, a 10% drop would be enough to completely wipe your balance out (since 10% of $10,000 is $1,000) but on the other hand, a 10% rise would end up doubling your money (from $1,000 to $2,000).
110  Other / Meta / Re: Imposter Warning for Newbies! (thank you) on: May 15, 2015, 08:49:38 AM
Fortunately the problem of imposter accounts seems to be an eventually self-correcting problem since the pool of usernames which might resemble a trusted user would get smaller and smaller over time. Grin

...Most people who have been on the forums for long enough will probably make sure to double check the username to see if it's the actual person who they're speaking with but sadly, sometimes this doesn't always happen.

Example:

How did he scam assets out of you?

He created accounts with names that were almost identical to names on the stakeholderlist.

So there would be dudexxx on the list and he would create an account dudexx.

I always check on the google spreadsheet with the search function if the PMs really came from stakeholders. If the search function finds the text you are looking for it marks the entire cell green not just the letters which is why i didn't notize the one missing character. Cell lit up green so I thought it was a match...

Link: http://bitcointalk.org/index.php?topic=677064.msg7673786#msg7673786

I retract the above statement because upon further analysis, I doubt even a warning message would have helped in the above situation I linked to:

...Of course all accounts were brand new but then so are many of our stakeholders so that didn't really ring any alarm bells.

So it's not completely foolproof although I suppose the presence of the warning itself might encourage people to become more vigilant in these situations. Sad

So the excuse: ''It would be too much work'' is a valid one? Then you could say that for anything and let every thief escape because it would be too hard to catch all of them so we let all escape. Is not that admins or mods have to assume the responsibility of anything, they only have to ban those scammers that are already confirmed, they dont have to do anything if there are proofs of their scam, thats why i said beyond reasonable doubt. I dont know if you follow me here

The number of scams where it can be confirmed to be a scam without a doubt is actually quite small. Usually it's only when the scammer confesses that you can remove every other possibility.
111  Bitcoin / Bitcoin Discussion / Re: Purchased a 10,000 BTC PUT option today, history has been made on: May 15, 2015, 08:28:11 AM
Not sure why so many people think OP actually bought 10,000 BTC. He clearly said in his original post that the option cost him $7.50 per BTC. 7.5*10,000 = $75,000.

I don't think it's a stupid move. Looking at the Bitcoin price charts, the trend has been going downwards ever since late 2013. Is it really that unrealistic to think that it won't continue declining for another couple of months?

I wonder what would happen if the coin price moves in the other direction. I'm sure you have all the plans put in place in case the result did not turn out as what you expected? By the way, just wondering where did you manage to secure that amount of funding? Kind of curious since that is not small amount by any means.

You're probably thinking of shorting, which is a different thing. An option is essentially a bet that Bitcoin will/won't be above/below a certain price on/by a certain date.

I don't get how this works. How can he acquire 10000 for 75$? Where is the business for the one offering the BTC for such price? I guess im missing the point here.

He didn't acquire 10,000 BTC. Here's a short explanation of put options:

Quote
If you are betting against bitcoins, what you want to do is buy a put option, which is a derivative contract that allows you to sell something at a set price. If the actual price of the thing falls below the set price, or strike price, you make money.

It cost $75,000 for OP to buy a put contract to sell 10,000 BTC at a strike price of $215 per bitcoin. The contract expires in three months and will expire worthless if the price of a bitcoin is above $215 at that point. But the value of the contract will go up before then as long as the value of a bitcoin drops.

If the price of BTC is $207.50 then OP could sell 10,000 BTC for $215 making 7.50*10,000 = $75,000. Since the contract cost $75,000, he would be neutral overall.

If the price of BTC is $200 then OP could sell 10,000 BTC for $215 making 15*10,000 = $150,000. Since the contract cost $75,000, he would have made a $75,000 profit, and so on. The lower the price of Bitcoin is, the more OP benefits.

Wait, I am confused.
So, this is like a guessing game?
He placed a bet, estimating that the price of Bitcoin will be under $215, and if it is he wins, if it's not he loses.
Is that right?

That's a very simple way of looking at it but yes, in essence you are correct.

He paid $75,000 for the right to sell 10,000 bitcoins at $215 per bitcoin in three months. For example, if the price is $200 in three months then he will be able to make 15*10,000 = $150,000. Take away the $75,000 he spent to make the contract and he ends up $75,000 in profit.

Obviously the more the price goes down, the more OP profits. If the price happens to be $207.50 then OP's situation remains neutral. If it happens to be any higher than that then OP would have lost money (up to a maximum of the $75,000 he spent initially).

EDIT: In my explanation you quoted, I probably should have used "for $215 per bitcoin" than "for $215". My mistake.
112  Economy / Micro Earnings / Re: How faucets make money? on: May 15, 2015, 08:07:31 AM
Aren't implementing captchas enough for this? Which ones would you recommend? I've been using Solve Media and ReCaptcha. And what other anti-bot measures are there (apart from captchas) that a faucet owner could choose to implement?

Is not enough, SolveMedia in security mode revenue or secure level 1 could be easy read with OCR.
I think recaptcha is the best one
But with phantomjs or imacro is it simply to simulate a human.
You also need a mouse detection, measurement of time and other few think to detect a bot.

The best way against bots is a email registration, but this is really annoying

Hmm... Didn't realize that. Perhaps that might explain why my faucets keep getting drained so quickly. Sad

I'll probably be shifting to ReCaptcha and testing to see if it's any better. I've noticed that ReCaptcha sometimes doesn't check to see if a captcha was successfully filled in (i.e. you just press a button and the system analyzes your behavior/setup and determines whether or not you're a bot based on just that analysis alone). Email registration would be very annoying, and I'm not sure if many popular faucet scripts out there support that either (at least not out of the box I think).

Anyway, thanks for the help. Smiley

I am running a faucet and I have to say:
all other ad systems apart from adsense, generate almost nothing
you have to have really big faucet to start receiving earnings from other things than adsense
I earn enough form adsense to keep the faucet going, but there is not much profit there. (some days 100% profit, but then 2 days in a row with 50% loss)

Doesn't AdSense require sites displaying their ads to be rich in content? I would have thought most faucet sites would fail this requirement. Huh

A skin implant with your private keys would be pretty cool.
I'd definitely do that.
I'll take the chance that if somebody really wants access to my bitcoins they'll have to cut me open rather than relying on my PC & paper wallets.

I'm guessing this is only for cold storage though right? An implant that transmits a signal such as the pill in the OP's article would be a huge security risk since the signal could be "grabbed" from you and analyzed/copied at any time.

A skin implant with your private keys would be pretty cool.
I'd definitely do that.
I'll take the chance that if somebody really wants access to my bitcoins they'll have to cut me open rather than relying on my PC & paper wallets.
That would mean your private keys are always on you, rather in a external location to yourself. It's a shitty way for protecting Bitcoin, same as this pill is absolute nonsense. The more 'advanced' the technique it seems its easier to get the information that can be protected pretty well with some basic techniques.

To be fair, an implant that doesn't transmit any signal could work quite well as a cold storage solution. The only way to access it would be if you were cut open. Or if you lost an arm, torso, etc. in some sort of massive traumatic injury.

Of course, the same problem also exists when you want to retrieve the funds too...

A skin implant with your private keys would be pretty cool.
I'd definitely do that.
I'll take the chance that if somebody really wants access to my bitcoins they'll have to cut me open rather than relying on my PC & paper wallets.

biometric would be better, but only with the scan of the eye not skin or other part of your body

so in this case you can unlock your smartphone by just looking at it, this would be very advanced and less annoying than a pill

Retina scans can potentially be compromised by high-resolution photography.

Another point: Assuming that the pill is evacuated out after digestion, what would prevent someone from the sewage treatment facility from collecting all of these pills and gaining access to the passwords of possibly hundreds of people?

Because swallowing a pill every 2 days is not an inconvenience. Plus how would it be a good way to have a cold storage wallet? Some robber could just put your phone near your chest to unlock your wallet.

Surely you mean that it is an inconvenience?
The idea would just be an addon to conventional means and it wouldn't be for daily use. It would be for rare times when you need to unload your cold wallet, so lets say you have 200btc and need to dump them for some reason, this would just be an added physical level of security. I can definitely see some possible uses.

Ah, OK. Well I guess that makes a bit more sense. Still I can think of more practical methods though.

Try this.

Strange. That link just takes me to a login page in Chinese...

Do not use proxy. Proxies are being re-directed to login. This is the link...

http://weibo.com/3552119670/Cg6HS4D9W

@ CCTV News
[Mo open strange e-mail in English spread! ] New Trojan virus struck, the most vulnerable foreign workers caught! It is spread through corporate and personal mail, e-mail in English, the Trojans were generally means "order" "Product Details" and so on, can be deceptive. Once caught, the computer 114 kinds of file formats will all be the Trojan encrypted and can not be opened. Want to restore a file, the only way is to pay a ransom to the Bitcoin Trojan author. (CCTV reporter Sun Yang)

I wasn't using a proxy. I think there might be some sort of geographical restriction which is redirecting non-Chinese IPs to a login page.

This is the page I get:

http://www.weibo.com/login.php

Anyway, thanks for the translation. It sounds like a variant of the CryptoLocker virus.

So if I understand correctly, a user needs to run this file first?
Which is sent to them via email?

If it's anything like the CryptoLocker trojan, then yes, it would need to be run.

Another ransomware case, are antiviruses able to identify it still or not? I think it's designed for windows only right? Or can it spread in Linux and Mac too?

Again, I'm only familiar with CryptoLocker but if it's anything similar then it should be Windows-specific. Malware which can infect OS X and Linux are quite rare.

It's going to be difficult to stop Ransomware. Once the Trojan is triggered all files targeted will be encrypted and then you are stuffed.

Without the key, your files are gone...

The only way to reduce the damage, will be to do regular offline backups. If you are hit, you could just restore the files and only lose the files that was not being backed up.

Most office workers do not make backups regularly.  Sad 

Businesses will probably start forcing backups soon if they haven't already been doing so. If everyone had backups, these ransom hackers would be out of business.

to be honest backup should be mandatory regardless of virus or other things, what if your hdd fail or other random crap like that? i've always an entire backup of my ssd in a usb pen drive

in this situation the victim could have just restored everything in no time without paying that crazy amount

It's also recommended to have backups of your backups.

And even that isn't necessarily going to be 100% successful. Stefan Thomas who is a Bitcoin core developer once lost a substantial amount of BTC because both his backups managed to fail simultaneously:

Quote from: Bitcoin Magazine
The Stefan Thomas Loss

This next incident is also fairly ancient in Bitcoin terms, taking place in July 2011, illustrates how wallet security can also fail in the other direction. Bitcoin developer Stefan Thomas had three backups of his wallet – an encrypted USB stick, a Dropbox account and a Virtualbox virtual machine. However, he managed to erase two of them and forget the password to the third, forever losing access to 7,000 BTC (worth $125,000 at the time). Thomas’s reaction: "[I’m] pretty dedicated to creating better clients since then."

Link: http://bitcoinmagazine.com/4628/bitcoin-self-defense-part-i-wallet-protection/

Guys, nobody has answered my question so far:

This trojan has to be ran by the victim right?
And it's send through email?


Much viruses and malware need the user of the computer, aka victim, to run an unsuspected file to be infected. Email is only one of the main source of these malwares. Others ways include plugging in a usb flash disks, downloading and viewing a pdf document.

PDF documents?
How does that work?
I have never heard of that before.
This is the first time I heard that.



There is a way called extension spoofing. Using the appropriate tool anyone can do it and it can be used to trick users download and run malicious files as well as files with malicious code attached to them. You can use extension spoofing on a huge variety of extensions but besides PDF is an especially vulnerable extension.

Basically this is correct. The Wikipedia article goes into more detail about the issue with extensions:

CryptoLocker typically propagated as an attachment to a seemingly innocuous e-mail message, which appears to have been sent by a legitimate company. A ZIP file attached to an email message contains an executable file with the filename and the icon disguised as a PDF file, taking advantage of Windows' default behaviour of hiding the extension from file names to disguise the real .EXE extension. CryptoLocker was also propagated using the Gameover ZeuS trojan and botnet.

Not to mention Acrobat Reader can also have vulnerabilities of its own which can be exploited if left unpatched:

We are using Php + MySQL with the style of Bootsrap.
The script won't be openly available like vBulletin etc. It will be only allowed 5 licenses per year
It can be used for clearnet and darknet

5 licenses per year? So does that mean that only 5 copies of the software will be sold per year?

How will the selling process work? Will there be a public auction?

Also, I don't see how it would be possible to prevent people from reselling the script especially in the context of the darknet. Huh

We make profit and it is really worth. You can easily double up your investment.
But you have always the fight against bots. Also you need a big experience to operate a faucet and one faucet is not enough.


Aren't implementing captchas enough for this? Which ones would you recommend? I've been using Solve Media and ReCaptcha. And what other anti-bot measures are there (apart from captchas) that a faucet owner could choose to implement?

I don't find it half-bad to run a porn business using Bitcoin. People are going to pay for these things and the freedom (plus "anonimity") Bitcoin can provide make it an even better choice. Sure, there a lot of shady things you can do with Bitcoin - they may even outnumber the "normal" things you can buy - but in part that is what got Bitcoin here in the first place (looking at you, SR).

Bitcoin can be made near-perfectly anonymous but I doubt most people are going to have the know-how to accomplish that. Point is, people are lax about their security and can't really be trusted to conceal their identity. Just look at this forum for instance. Sockpuppets are being unmasked all the time often via taint analysis but sometimes it's been the case that people have reused the same address over and over multiple times. The anonymity/pseudoanonymity doesn't really factor into it IMHO and if the authorities were really determined to unmask someone's identity, they would be able to do so successfully in 99% of cases.

It is pretty bad, to be honest the only reason I started a porn site, is cause no one was taking full advantage of bitcoin's feature set it is kinda sad.

Also it isn't easy to start one, most girls have no idea nor care about bitcoins.

The way around this problem is to create a bridge. Allow users to pay in BTC, and then use an intermediary (like BitPay) so the girls get paid in cash. Now they don't care about BTC, nor need to know about/have it, and users can still benefit from the anonymity and ease.

And what would prevent the authorities from going after this company then? As well as shutting it down, confiscating logs, etc.

I see that you are using a-ads. What is the profit per week? Even if it's a small amount like 50 cents, I'm curious. Send me a PM if you don't want to post it here.

And where are the jokes? When I visited your site, all I could see were articles and pictures of altcoins... Huh

I've used a number of different publisher sites in the past couple of months, so it is unclear what the exact profit is. I would average it around $0.50 per week. The thing is...the site costed nothing to build and currently has no monthly expenses.

As far as the jokes are concerned, you can see in my signature that the focus is really "Funny Articles", so the jokes are in the content of the articles, pictures and videos on the site. If anyone wants to buy the site, they can feel free to add a "jokes" page. I see a lot of potential for the site but I don't have a team to handle or manage all of these things.

That's actually higher than I had expected. I've used a-ads in the past and was able to make barely over 5 cents. I agree about the potential thing. Weebly is OK, and there are blogs hosted on Blogger (another free website creation platform) which have been quite successful in the past but the site would look more professional and attractive to potential buyers with a nicer template and without the Weebly branding.

Anyway, good luck with your sale. Smiley

We can just buy a domain at Namecheap at a very cheap price. We dont even need to use Weebly, just download Wordpress and it will work better than Weebly. Wordpress have lot of plugins and themes. I dont think CCJ worth 0.5 Bitcoin.

Installing WordPress usually requires you to sign up to a paid hosting contract. WordPress.com is free but it doesn't allow ads (instead they place their own). There are free hosts out there but they're not very good and most have ads (not yours but theirs).

SatoshiDice has a long history and was once the largest dice site but ownership of the site has been transferred at least once in the past (although the sale involved a huge sum of money so it's unlikely that the new owners would use it to scam). PRCDice.eu has been online for almost two years and have enjoyed an OK-ish reputation so far. DaDice is very new but they have become popular very quickly.

Actually SatoshiDice hasn't been accepting US based players for almost two years now:

Quote from: CoinDesk
Citing legal advice, Bitcoin gaming site SatoshiDice is closing to US players, moving to block all US-based IP addresses from the website.

Posting on Bitcointalk and the Bitcoin reddit page, satoshidicepr, an official representative of the site who asked to remain anonymous, said the decision, which is effective as of today, was taken following “extensive legal counsel.”

Source: http://www.coindesk.com/bitcoin-gaming-site-satoshidice-closes-to-us-players/

US players can play the on-chain SD game by getting a SD address on https://blockchain.info/popular-addresses without accessing the page.

Ah yes, before I knew about SatoshiDice having an off-chain game, I always wondered how they were able to block US-based players since I thought only their on-chain game existed.

Also, everyone in this thread is just posting either their own dice site or the one they have in their signature. There doesn't appear to be any consensus at all as to what dice site other than PD and JD are considered the most trustworthy.

DaDice has been mentioned a few times but they are far too new to be considered trustworthy IMO no matter how popular they become. They definitely have potential though and if they manage to continue operating for a while longer without any major issues, then I suppose they could eventually become a very important player in the field.

Biggest problem I see is that PD and JD exited the US market for a reason and any dice site that grows big and trustworthy enough will want to avoid the US market for the same reasons too unless they want to become a target for authorities. Sad
