It is good service, do you have plan adds altcoins price chat in the future? I think it will make more famous and there are many people who use your services, because there are many choice on this service.

It's possible but definitely not coming in the near future.

Is this tool down? I'm getting errors on all the images:

Fixed. Thanks, and sorry about the problem.

Today I found I couldn't fully load bitcoinity in either firefox or chrome. The real time price data won't load in them. I tried it in internet explorer and got this warning that there are security certificate errors.

Should be fixed now, thanks.

When I swap the markets view I keep getting this error. The most recent trades all show up as an hour old. Everything works fine until I swap to a different market view. Is anyone else getting this problem?



Huh, not to me, fun thing is these are shown as from the future ("in 1 hour" not "1 hour ago"). It should be using time offset provided by your javascript, so timezone should be irrelevant, I'm assuming your local clock is correct? does "new Date()" in JS console  gives you proper time? And if both are fine, what timezone are you in?

If anybody else is experience this I would also appreciate some feedback.


I think it would be nice if we could add a way so that when I hover over the volume I can see how much exactly it was.

I'll try to add it, but only if first I do what somebody else suggested, that is for bars to be exact timespans, like 1d or 5m or whatever (currently it just splits whole displayed timespan evenly), only then it makes sense to know exact value I guess. Both these things are implemented on http://data.bitcoinity.org though.

i expect to see a response to my accusations on the previous page

I don't consider them being worthy a response (as accusations). Although around the time you posted it, that is ~ Aug 2014, I did see some live market depth issues on bitstamp. I haven't changed anything on my side before or after, it could be some edge case in my code but I would risk suggestion that it could be something on bitstamp side. However I've seen they currently have some new different API so I'll try to update to the new one, nice they kept the old stuff but maybe it's not getting enough attention so it's faulty sometimes. Too bad their new live depth API is... well its design sucks IMHO.

Coinbase on the other hand did live market depth API in a very sane way which actually allows to keep proper state of the orderbook.  I'm not updating this thread often so probably already known but I added them as soon as they lunched the exchange http://bitcoinity.org/markets/coinbase/USD

I had some db problems lately so http://data.bitcoinity.org was working quite randomly, this should be resolved now, but I will need to do one more maintenance which may take up to an hour (I'll put some notice few hours earlier)

Also some exchanges are in the queue to be added but I need to finish cleaning up backend first. Even if I don't reply, I read all suggestions and have some quite long todo list with many of them. Wish I would put some more time into this but my main focus currently is on something else (and I want to keep bitcoinity without any ads other than info about sponsoring).

I've reached a functional form of a "replacement" as of now and would like some feedback while working on a final version. For the time being downloads are free but subject to change.

https://untorrent.me/



Awesome.

some feedback:

  • I was getting download speeds > 10MB/s when downloading back to me, but the download never finished (it was stopping at random points)
  • magnet urls seems to work in the way that the name gets displayed but they don't seem to download
  • when trying to add some other file after refresh I kept getting "failed to add torrent", maybe you were changing something

I'm probably back.

Sorry about the cert, it's gonna be updated today.

I'll post more replies later, regarding counter at the bottom of the page, please don't trust it too much. The reason I don't have graph of it over time is because I keep getting some problems with the module that handles live updates, and sometimes subscribers stop being counted, while sometimes there seem to be some hanging and it will go down like 20% after restarting servers.

I don't know what happened, but it used to be an excellent service. I hope it gets back, if not then some alternative is badly needed.

I wish it would get back because the owner has made the right choices. It was doing what it was supposed to and it was doing it very well. I also tried some old funding address without any luck (probably bitcoind died?). Fetching still works fine.

hmmm bit confused here. how is it possible that OK Coin has less volume in the last 6 months, than the last 30 days?

https://bitcoinity.org/markets/list?currency=ALL&span=6m
 okcoin   279,155   BTC (6m volume)

https://bitcoinity.org/markets/list?currency=ALL&span=30d
 okcoin   1,078,781 BTC (30 day volume)

6m is 1,180,760
30d is 1,086,843

It's not much higher because I only have their data  from the last month. I guess  it's possible you saw some version with a cache still back from the import time, it seems 6m total volume cache expiration time is as high as 5 days, I'll fix that to make this period shorter.

Just in case no one has noticed, but the bitcoinity site is having problems...looks like the CSS and JS are no longer there?

I can't reproduce. Does anyone else can? And what browser/OS is this happening on?

Where is the charts from Kraken?

Kraken is getting the shout out for being the first exchange to take some serious steps towards proving their bitcoin solvency. Their solution ( https://www.kraken.com/security/audit ) is not perfect but it's better than what any other exchange has done so far. It's going to be just 2 weeks because it's not a full proof of solvency i.e. it still depends on trust to the auditor. I'm happy to promote them because based on my talk with them my subjective opinion is that they know what they are doing.

They plan to release audits quarterly. I definitely would like to see these more often, and with direct proof of control of the bitcoins. I hope this is just a first step to a better future when such proofs become a standard. But a lot of this depends on the community. You can ask your exchange to improve their transparency, and you can vote with your money.

I like you BitQuick and you know it but..

Apart from the fact that you are not a standard exchange where customer can store funds and trade them realtime (as far as I understand it), your proof does not seem to be optimal to me. Solvency proof has too parts to it: 1. Prove that you in control of some amount of bitcoins. 2. Prove that sum of users bitcoin liabilities are smaller or equal than that. I don't see either of that.

I've also been contacted by bitalo.com (even before bitquick), they are using multisig and (based on the description) they are doing it right, so that you have full control of your bitcoins and no solvency proof is necessary. I like that very much, but again, that's more like a marketplace. It's something very good and it has its place, but it's not an exchange in a classical meaning.

I just got info from kraken and I need to take a detailed look since I just woke up, but it's possible that's what I've been asking for.

Regarding other posts, sorry for no answers lately, I'll post them soon-ish

You surely would be able to recover them from your previous backups, right? .. Right??
14  Economy / Trading Discussion / Re: bitcoinity.org/markets - live bitcoin price charts on: February 27, 2014, 01:19:47 AM
Bitcoin central added.

Is there a reason that the Mt Gox Euro chart is still displayed while the USD chart was removed?

Cache. I didn't remove anything, it's just sorted by volume + some cache (~24h).

The charts on data.bitcoinity NEED a button to toggle log-Y axis. All of them!

Agreed, I'll add it soon. I mean like really soon.
15  Economy / Trading Discussion / Re: bitcoinity.org/markets - live bitcoin price charts on: February 22, 2014, 02:03:44 PM
Never gonna happen... not necessarily because all exchanges are fractional, or anything nefarious necessarily, but for privacy and security reasons.

Can you provide these privacy and security reasons?

It certainly isn't going to happen if users are not interested in it. Unless users want it, exchanges have no interest in proving their solvency.
16  Economy / Trading Discussion / Re: bitcoinity.org/markets - live bitcoin price charts on: February 21, 2014, 06:56:15 PM
There was some discussion today that started around here: http://www.reddit.com/r/Bitcoin/comments/1yj5b5/unverified_pastebin_gmaxwell_irc_log_mtgox_was/cfkze3p and here's some more explanation: https://iwilcox.me.uk/v/nofrac

TL;DR exchanges can prove that:

  • they own specific amount of bitcoins
  • and that your bitcoins on their exchange are included in this amount

But they are not doing this yet. I'd like to do something towards changing this.

I'll give a shout out on Bitcoinity to the first exchange that implements it, and it will be displayed for a week under the page title (where sponsors are displayed). Another 3 weeks are going to the first exchange that implements it with volume over 1k BTC over the last 30 days. Exchange must include BTC/USD pair and it's not relevant whether it's currently listed on Bitcoinity or not (although it must provide full API - list of latest trades and orderbook).

I'm considering sorting exchanges not only by volume, but first including those that provide such proof if the idea works out.

edit: to clarify, it does not have to use this specific implementation, as long as the one that it uses works as a proof

Temporary (I guess) addition: http://bitcoinity.org/markets/bitcoinbuilder/GOXBTC

I set the main default for the website manually at the moment (and it's USD/bitstamp). For everything else there's just algo that decides this based on exchanges and currencies volume. I set what you see when you first enter website manually because otherwise it would be huobi/CNY and not many people want to watch that. When you enter the website second time, you are displayed what you have been watching lately. So newcomers see USD/Bitstamp, others see what they visited lately. But yes, when you click on the currency you see the biggest exchange for given currency first.

I'd like to provide unbiased data, that has nothing to do with my personal opinion. Maybe mtgox should not be default for EUR. *Maybe*. But I'm not sure. I'd rather be coding than keeping track of all exchanges news, especially when it seems really hard to be able to track down facts and not just people opinions. If I would use my personal opinion, btc-e for example would not be on the website anymore based on my support experience with them.
19  Economy / Trading Discussion / Re: bitcoinity.org/markets - live bitcoin price charts on: February 16, 2014, 05:15:55 PM
Maybe it is time to remove the MtGox charts, because its not relevant any more.

I've answered this so many times already. I just provide charts. Exchanges are sorted by volume. I'm not forcing anybody to watch mtgox if they don't want to. In fact, even though mtgox has the highest volume, exchange displayed by default is bitstamp. 1/3 of viewers are watching mtgox.

can we have a graph of the number of connected users VS time

I've changed my monitoring tools lately, so without any acrobations I only have a chart from the last month:

FYI, fixed it by switching antivirus from bitdefender to avast.

Thanks for the info. I'm still wondering what could cause it to block it. Were you using https version or normal?

Btcmarkets.net and Anxbtc.com added, also some http://data.bitcoinity.org updates like an arbitrage table, or orderbook stats over time and some bugfixes.
