You might want to add a link directly to your site in the OP so that people who come here don't have to type it out in order to visit it. Regardless, I just checked the site and it looks quite fine. My question to you is, how does this differ from other similar wiki sites related to Bitcoin that are more popular such as, say, bitcoin.it? It seems to me that there isn't much more information that would differ between the sites as most all of it is just the normal Bitcoin facts. I assume you plan to cover cryptocurrencies other than Bitcoin as well? I do appreciate the ICO point, however.

I posted something about Wagecan recently in another thread that might be useful here as I see discussion about it.

I recently got a PM from a Wagecan rep (weiting@Wagecan - https://bitcointalk.org/index.php?action=profile;u=963014) after having posted in the Advcash debit card thread. He was promoting their own debit card that I took some time to check out and consider among my other options. My only problems with it are that the limits are much lower compared to other cards given by other vendors given comparably ID requirements and that their debit card, unless I am missing something obvious, costs over $100 (am I even looking at it right?) according to their pricing page on their website: https://wagecan.com/Pricing. Not sure if anyone has any experience with them. The rep gave me some links, but I would like to know no-bias.

Wagecan issued virtual USD card ?
need ID + proof ?
No. To be clear, while they did contact me about their newly released card, I did not take them up on the offer. They did require too much ID + verification which was way past my limit. This is the reason why I openly asked if anyone here had any experience with them, as I would feel very uncomfortable giving away any information to an unknown party without any significant reputation.

I can't seem to find any configurations with the NVMe option, unless they are listed on a separate place other than the VPS tab under your offered services? I can only see regular VPSs, web hosting, and domains, so I do not think this is the case. Also, what is the difference between an NVMe SSD and a regular one?

EDIT: Nevermind, I'm clearly blind. It appears once you click on the "Configure" button.

Seems like a few people are having issues with this card. Really looking for alternatives to cryptopay and wirex right now, does anyone know whether or not Uquid is worth a shot for an unverified account?

2-3 weeks my arse... uquid, your reputation really has gone down the shitter at this point.

What was your problem with theM?
It's not that their reputation has gone down, necesarily. Personally, I don't see the present situation as all that bad. The complains right now stem from the fact that UQUID lost their card provider because their contract ran out and are now on the lookout for a new one. They stated a few weeks back that it would take 2-3 weeks to get a new contract. I am not familiar with the inner workings of these deals, but I assume they have to take some time to develop and integrate into the current ecosystem. You can't buy cards or load current ones because of this, but you can still spend what's inside them. I never had any other problem with them, so I wouldn't be worried. That being said, you should look elsewhere at the moment.

suppose you have the following tools available;

1. Two trezor hardware wallets
2.offline bootable pc with ubuntu
3.bitaddress.org siteburned to a CD

There are laser engraving machines that are selling on Ebay for $71 now. They look like a little 3d printer and you can hold one in one hand.

This type of machine would allow putting keys and squarecodes on anodized aluminum plates or painted steel plates. They would burn through the paint or anodized layer.

I suggest this as a way to avoid all the issues of paper getting wet, mildewing, rotting, catching on fire, etc.

Although it's possible that an engraved steel or aluminum plate would not survive a fire with the engraving legible. Still a gigantic improvement.

The problem with that is that the cost for doing it is too high, and it might not be worth it if it made up any significant portion of your worth im bitcoins. On the other hand, we could simply keep separate and several backups in safe places and the store a brain secret to decode the seed or private key. This way, it is very unlikely that the coins could be obtained by anyone else or lost by the owner.

... every experienced programmer/user knows that with java script the programmer/administrator could steal your cookies (from any website) and forcing users to perform actions that they did not intend (IP LEAKING?! and much more) very unsafe for a mixing service.
I'm assuming you actually mean... "very unsafe for USERS of a mixing service"

But my question would be, why would the programmer/administrator need to steal cookies from users? The users are voluntarily giving them BTC... Who cares about some IP addresses and cookies when you can just wait until you get given a bunch of BTC and walk away... why hack your own JS? Huh

I see that the other site utilises PHP... a quick perusal of google using words like "php" and "vulnerability" cough up an awful lot of pages regarding security flaws in PHP... just like there are many ones about JS... At the end of the day, you are putting faith in any 3rd Party service that they have used appropriate methods to secure their systems, regardless of the systems in use. Using the "safest" system in the world isn't any good if you leave the door unlocked Tongue

Also, while it is a great show that they've put 10 BTC in escrow... aside from the word of the mixer admins and the escrowing party, is there any real way for them to actually prove that they are actually independent of each other and they're not best friends (or the same persons)?

#foodForThought

Why would EXCHANGE exit scam? why would DARKNET market exit scam? javascript is  simply a very smart way of stealing money, user is trying to mix his bitcoins and got infected by miner or malicious Trojan that expose his computer to hackers to steal a bigger amount. Who's using unsafe website with javascript is a totally idiot.

such a mess. just sent some coins, a quite large amount actually to your mixer, and 5 sec later the website was down

504 Gateway Time-out

fuck, what to do now??
If clearnet site is unstable, please check Tor one. If you cannot, wait till we get online. You have 48h. You can also send us an e-mail to extend your session.

they put 10 BTC in escrow
If you have 5 BTC daily volume then it is good amount of escrow.
If you have 100 BTC daily volume then it is false security.


I guess you will never know how much bitcoins they actually mix and what's their  daily volume. they put something in escrow, something u haven't done. disable javascript for your customers sake

For the record, this guy has no idea what he's talking about and is most likely just trolling. Instead of trying to argue with me, he ad hominemed his way through the discussion. I also talked to the manager of the campaign that he was allegedly participating in-- it turns out he was never even accepted into it. I have no idea why he is doing this, but I feel the need to mention this because all of his accusations against ChipMixer are complete spam and completely unfounded. He simply has no idea of what he is talking about and is probably desperate about bumping up his post count and joining a signature campaign, as he can't seem to get into one.

In other words, just ignore him.
447  Bitcoin / Development & Technical Discussion / Re: How to design a perfect cold storage? on: September 26, 2017, 03:08:09 AM
Passphrase is limited to 50 charachters on Trezor, so there could be a bit less words, is it still secure then? Also should you choose words with dice or just pick some sentence that makes sense just to you?

Maybe you mean "50 words" If that right, 170 000 ^ 50 combinations are possible.

If you mean "charachters" then we have  (numbers of English letters + number of numbers + number of keyboard symbols) . It's very strong password as you could see) ^ 50
Also you may notice that mnemonic phrase is stronger than passphrase. mnemonic phrase has 170 000 ^ 10 possible combination while passphrase has  60 ^ 50 .

Yes, this is the math that I followed previously. If it takes only up to 50 characters (I am personally not familiar with Trezors, so I do not know their limits) then somewhere around n^50 would be the maximum number of possible combinations where n is the number of accepted symbols. You can still use words and assuming that each word is around 6-7 characters in length you may be able to fit still 8-9 words in there which mathematically speaking still makes up a very strong password of up to 170K^9 possible combinations. Using just characters could be even more secure in this case, though.
448  Economy / Exchanges / Re: List of bitcoin debit cards on: September 26, 2017, 03:02:28 AM
Guys, Which one do you use/Recommend?

Thanks

At this point it really depends on where you currently reside and what your specific needs you have and what verification limits you are willing to comply with. For example, Shift is pretty good if you are not looking for any privacy and just want something that works and has good reputation, while something like SpectroCoin is good if you would like to stay anonymous and don't like fees very much. Also important to note is that most card-providing vendors do not provide cards to customers that reside in the United States, at least not without significant amounts of verification. The 2 providers I listed both work in the U.S., however.
449  Economy / Service Announcements / Re: [ANN] ChipMixer - mixing reinvented on: September 26, 2017, 02:58:48 AM
i've no idea if ddos from another competitor but honestly nothing possible,because too much bitcoin mixing service now

At this point it's safe to say that there aren't any actual competitors for ChipMixer -- all other mixers have not yet proven to be fully trustworthy, which results in them having a hard time attracting more people to use their service. I am glad that ChipMixer is building itself up nicely, otherwise I would basically be forced to expose my funds to great risks when making use of a mixing service that is relatively new in the game, and that's obviously not something to look forward to.

Chipmixer's website is mostly based on java script (NOT SAFE?!) and unlike the company in my signature (they put 10 BTC in escrow) they don't have any guarantee. their  private keys could be hacked and leaked. So I think you got it completely wrong lad.

Huh? What do you mean JavaScript is not safe? As a system administrator and developerwho has used JavaScript very widely before, I can tell you that this is completely unfounded. JavaScript is only unsafe if you code in such way as to allow cross-site/external JavaScript scripts to run inside your website, which I am sure anyone with some decent knowledge of JavaScript knows how to prevent. Furthermore, there is no reason to trust whatever mixer it is you are advertising more than any other. You failed to elaborate on your point and just blindly claimed that their guarantee is to be trusted.
450  Bitcoin / Press / Re: [2017-9-22] BREAKING: Amazon Will Accept Bitcoin By October on: September 25, 2017, 08:36:25 PM
It's decent news, but people shouldn't expect the price to react on this -- merchant adoption is no longer a price driver. I am not an Amazon user at all, but there is no way anyone can deny their large market share and dominance. At the end of the day, even though they might be accepting Bitcoin, everything will get dumped on the market by their third party payment processor. Only when merchants are going to hold a certain percentage of their Bitcoin sales, the Bitcoin price might end up reacting positively.

I disagree. Merchant adoption is a pretty big price driver when it comes to big merchants such as Amazon, which is the most popular online retailer in the west. The actual fact that they accept Bitcoin is not in and of itself a good cause for Bitcoin value to go up, since as you said, they would most likely be converting the bitcoin as soon as they get it, but the fact that it can become an option increases the popularity of the Bitcoin name which may interest more people and inherently give more value to the currency, since the general demand for it would go up. The actual price delta is arguable, but the effect would be very real regardless simply because of the promotion of its existence.
451  Bitcoin / Development & Technical Discussion / Re: How to design a perfect cold storage? on: September 25, 2017, 01:19:07 AM
Is leaving seed in unlocked place at friends house a risk if there is also strong passphrase on it or is there risk somebody could see seed and brute force it? Even keeping in bank safe seems a bit risky.

It would depend on what the passphrase to your seed is. If it is long and complex, say at least 12 characters including special characters and numbers, then you should have nothing to fear. The amount of time it would take for such a passphrase to be brute-forced is not within what you could call reasonably or efficient. You could also just use a set of words to end up with an even stronger passphrase. Given a strong passphrase, you should also feel fine about having multiple copies of it stored in different places. Just make sure that your passphrase and seed never meet, since anyone who has access to both of them at once can (and probably will) open your wallet and potentially steal your bitcoins. A physical copy of the seed and a brain copy of the passphrase is a good combination. Make sure not to forget about other possible attack vectors such as malware, however.

So if you find seed couldn't you rent out computer cluster and crack passphrase?

Not at all. You could get all the computing power in the world and it would still not be possible to crack it in any reasonable amount of time. And note that my definition of reasonably is very wide in this context. We're talking about being unable to crack a passphrase within a million years. Now, I have also heard from some that quantum computing may change things around in regards to cryptography, but I personally don't think in this situation it would matter. Of course, in the end it depends on how long and secure a passphrase you use. However, if you use 10 random words as your passphrase, you can rest assured that your seed will be safely protected and you have nothing to fear, as the difficulty in that is n^10 where n is the number of different possible words. Using any possible words in the English dictionary, currently around 170K, would result in 170,000^10, which results in 20159939004490000000000000000000000000000000000000000 or 2x10^52 possible combinations. In other words, don't worry about it.

Nobody here seems to have mentioned that there are already 2 threads discussing this matter. Here are the links:

https://bitcointalk.org/index.php?topic=1410577.0
https://bitcointalk.org/index.php?topic=1242788.0

In my experience, I have had success with both UQUID and SpectroCoin. The problem with UQUID right now is that it is not currently possible to create cards or load current cards, as their contract with the card provider ran out and they are looking for a new one. SpectroCoin works but I am not convinced by their support, as some of what they have claimed in regards to fees contradicts the experience I have had with them, but functionality-wise, their card works just fine. Feel free to check both of them out.

I would like to know what the reputation of these sources is. I do not ever go into any crypto-specific sites to obtain information or news on Bitcoin or any other crypto-currency, so I am not sure that any of this can be trusted. If this happens to be true, however, it is truly a huge step for Bitcoin as Amazon is one of the biggest online retailers on the web and would potentially increase Bitcoin knowledge to the general public by a good bunch. If it is just a rumor, then services such as Purse.io would still work for purposes of buying products from Amazon with bitcoins.

For now, the "easiest" way is record all your income carefully and calculate them in the current price when you get it. And i've never seen software that can do this hard thing Roll Eyes
Yes I also agree with this that there is no software in this day to calculate something virtual, but may be possible in the coming future. That would be so amazing. But now you will have to calculate your bitcoin price by the time of transaction and the current value of the bitcoin.

So I think we will have to wait for this kind of software, because up to date we don’t have any. Just look at the software developers.
This type of software is not a critical or very complex one like those needed by NASA. It can be created by any junior developer even. The requirements are not a very tough one. There are simple calculations. Simple form of input data, some mathematical functions and that's all. If someone wants it, he can post it on freelancer's websites.

I agree, and it is also no math that could not be simply added to an already existing accounting software. Even plugins or add-ons for existing software would do the job just fine and the development time would be minimal. You could probably already classify Bitcoin as one of the pre-existing asset types in most major software, however.

For now, the "easiest" way is record all your income carefully and calculate them in the current price when you get it. And i've never seen software that can do this hard thing

I have no idea what you are talking about. You literally just described regular accounting software. It is no rocket science and already exists. You follow historical cost if you need to, which is already a feature essential to any decent accounting software. You clearly have never seen any before.

I suspected as much, but figured it wasn't my place to say so... honestly, why do people do this sort of thing? What do they gain out of it? Huh

Perhaps other mixers desperate to destroy the competition? There are some with a dodgy reputation who are probably struggling to lure victims. Then you have those offering genuine and legitimate mixing services but can't make ends meet with the low turnover from the few users mixing coins on their sites.

Then of course you have those malicious actors who take pleasure in destroying other people's work or who resent their success.

Envy knows no bounds. People filled with it will do things that cross the bounds of human decency.



Eh, it's actually fairly worthless to try to do it that way. A DDoS attack is only a temporary method of attacking a website in the sense that once it is over, it's over without any real consequences afterwards. The denial of service also can't really last that long without too many resources. I don't see any mixers really benefiting from doing this either, but it is certainly possible to try to get the business of those people trying to mix their coins at that time and then looking for an alternative. There really isn't that much to gain, though.
458  Bitcoin / Press / Re: [2017-09-21] Bitcoin's not a fraud … but don't risk it on: September 21, 2017, 04:31:44 AM
I know that a Bitcoin forum is probably a bad place to say this, but there really is no guarantee to the future of Bitcoin, whether it be a good, prosperous one, or a bad one in which it crashes back to nothing. To the average person, I certainly would not recommend investing in Bitcoin in big amounts unless proper research is done and the risks are properly calculated. In this sense, Bitcoin really just acts as a more volatile asset which may not be worth the risk for some. Circumstances matter, and are the sole reason I am invested in Bitcoin, but that is also because I have many fail-safes in case something goes wrong.
459  Economy / Service Announcements / Re: [ANN] ChipMixer - mixing reinvented on: September 21, 2017, 04:15:09 AM
Why not have it set up where there is a fee scale based on how long you keep your coins on the chipmixer system? ranging from investment return for keeping your coins on for a long period, to paying higher fee when you remove your coins immediately. something like this.

+3 months= +1-2%
2 months= +.50-1%
1 month= +.10-.50%
10 days=  0%
5 days = -0.10- -0.50%
1 day= -0.50%- -1%
immediate withdrawal to 1 day = -1- -2%


This is a very interesting idea. Now you can either withdraw your chips and receive private keys or you can take voucher to withdraw them later. Taking the voucher keeps your chips in the pool.
We could add an investment return for vouchers ie. you keep 1 BTC voucher for some time and when you redeem it you get more than 1 BTC.

The only problem I see here is that it looks exactly like pyramid-scheme. All the accountability that ChipMixer is proud of - we do not keep your funds, we give private keys immediatly - is missing from this investment idea.

Please check your PM, I have sent you 32 mBTC voucher.

Besides the pyramid scheme stuff everyone is talking about, another problem is that vouchers could be all saved up and reclaimed at the same time, and if this is done at a large scale, it is unlikely that ChipMixer is going to have enough chips to redeem the vouchers. Other than that, I do agree that it could be seen as a potential long-term scam, so maybe it is better if it is simply kept as it is. No point in playing with the trust that you have already earned and risk losing it.

This poster brings up a good point:
I'll try it out as long as it isn't blackhat

Is this white-hat or black-hat? I would not like to be hurting the actual people doing the deliveries (think no tips for the poor guys) since they are just trying to make a living off that part-time job. If it is fully on the corporate or intentional business level and could be seen as some sort of marketing strategy or loophole in their registration process, however, it might be ok. Otherwise I do not think such a method should get out there. Also, how likely is it to get patched by Uber in the near future, since I assume it is not necessarily intended?

It is grey hat, you won't be hurting the workers or deliverers, but you will be hurting uber as a corporation

To be honest, given the kind of company Uber is, I don't really care if it hurts them, especially if this method is a result of a flaw in the design of their software or registration system. What are the chances of this method getting shut down? Does it involve creating multiple accounts, and if not, how long does it take to do this method, as if it is too long it might not be worth it.
