Bitcoin Forum

I just registered bitcoinpeak.com and bitcoinpeak.org

Does anyone feel like writing a quick one page website for me that simply shows "the highest bitcoin price ever"?
Currently it could a static page showing $31.X (I don't remember what the exact peak, Google-fu didn't help me)... but we'll soon overcome it.

Full credit will be given to the coder. It's really not for profit, just a fun website to have.

I'll donate 1 BTC for a clean implementation of this.

Any jumpers?

Shure,

I can make a neat little PHP class that pulls historical BTC/USD exchange rates and returns the maximum price and its timestamp.

Heh, actually it was not intentional :)


Cool. Can you wrap it in a minimal design (nothing fancy at all, just centered div with border and background)?
Set it up on some server and I'll point my DNS towards it.

Also while you're at it you I suggest adding Google Analytics.

BTW for the 1 BTC donation I need to get access to the code, I suggest just posting it publically at github.

Shure.

I'll send you the code in PM and you can do what you like with it :)

Ah, now you are changing the specs in the middle of the project :P

I'm not a web designer, so adding markup isnt really my thing.

I'm not shure what you are asking with regards to the server. It looks like you want free hosting?  :o

I've made the class availabel to you for download on http://bitcoin.gdsl.no/bitpeak.zip (http://bitcoin.gdsl.no/bitpeak.zip).

Donation can be sendt to 1PHPJobsU1bRJh1UJk7HfwR2eHbuzhyd9P (http://blockchain.info/address/1PHPJobsU1bRJh1UJk7HfwR2eHbuzhyd9P (http://blockchain.info/address/1PHPJobsU1bRJh1UJk7HfwR2eHbuzhyd9P))

Well, what I had in mind is someone setting this up on some throwaway server.

I see the code is rather simple ... I guess I could have coded it myself and saved myself a bitcoin, but I'll keep up my end and send you that 1 BTC once I had a chance to check it out. Thanks!

According to bitcoincharts.com, the Mtgox all-time high is $31.9099. Any minute now...

I will donate space for hosting if you didn't already have something lined up

Heroku :)
I think I'll just convert the php code to java/scala because I'm more comfortable with it, and push it to heroku.
Thanks for the offer though!

Interesting, blockchain.info is wrong here ... it says the peak is $35

{"x":1307729705,"y":35.0}

In http://blockchain.info/charts/market-price?timespan=all&format=json

Here are a few data points from the time (June 2011)

{
x: 1307556905,
y: 31.9099
},
{
x: 1307643305,
y: 31.5
},
{
x: 1307729705,
y: 35
},

I guess I'll manually ignore them.

Yeah, I don't know why it says that. Maybe it uses a different exchange, or maybe bitcoincharts.com missed some of the trades.

Anyway, I just ignored those two data points.

It is ready - http://www.bitcoinpeak.org/

Code is here (Scala/Play 2): https://github.com/ripper234/bitcoin-peak

gdsl, I'll send 0.5 BTC to your address. I really expected more when I posted my donation ... I ended up doing quiet a bit of work (not just because I choose to convert it to Scala/Play). E.g. caching of the result is important in order not to waste time on every page view, ordering the app in a proper view etc.

Hope no hard feelings regarding the missing 0.5 BTC.

Actually I do.

Your request was:


I beleave I fulfilled your request quickly. It should not be my problem that you didnt know how to make the egg stand on its end.

Additionally, you are now going back on your reconfirmation on the 1BTC bounty.


If the last 0.5BTC remains unpaied I will not work with you again.

If you don't send him 1 btc, you will get a scammer tag.  It is up to YOU as the person who made the contract, to be specific if/when you need to.  He did exactly as you asked -not his fault you asked for so little.

in the IT hardware industry, we call that "moving the goalpost".  In your case, gdsl, you had a clearly stated ask, and a clearly stated reward for fulfillment. Him moving the goalpost after the initial agreement was made is just dirty pool, and he owes you that other BTC0.5 ASAP.

If he doesn't pay the other 0.5 BTC, report him in the SCAM ACCUSATIONS forum.  Open and shut case, and it will let the other forum members know that he goes back on his word.

I also see he did not give full credit to the coder on his website.   hmmmm

odsl - I offered 1 BTC for a clean implementation that works.
Your implementation was buggy. Did you even run it? It returns $35! Not to mention the other issues I mentioned.
Your code is a POC, nothing more. I wanted to pay 1 BTC for someone working and production grade to save me the work and upload a working website to somewhere (e.g. heroku ... no need for free hosting).

Nevertheless, after reading your initial reply on my smartphone a few hours ago, I decided to send you that 0.5 BTC ... $15 is not worth one of us leaving this thread with grudes.
Sent.


Geese, let a man reply before giving him a scammer tag ... I was away for a few hours today.
I wouldn't get a scammer tag, this was not a contract nor a bounty, just an offer for a donation.
Some proportion, people.
Anyway the threat of the scammer tag is not why I'm paying this up ... I honestly don't want anyone to feel cheated here.


This was not a job contract. There were no clearly defined terms for completion, but I did write:


- I didn't get a working implementation
- The code he submitted wasn't a website/webpage, it was a function
- it had severe bugs


Sorry, credit would have been given if the coder has implemented the above.
I'll pay the 0.5 BTC, but I won't give credit to someone who just basically pointed me towards blockchain API and gave me a POC, and let me labor for 2 hours afterwords to create a production grade product.

Again, some perspective people. You can request I get a scammer tag for failing to give full credit if you want :)

Thanks everyone, a total of 1 BTC paid, have a nice day.

Your statement that the code is bugged is untrue and dishonest. The code is available for peer review on http://bitcoin.gdsl.no/bitpeak.zip (http://bitcoin.gdsl.no/bitpeak.zip). It does return $35 as the peak price as this is the data returned by http://blockchain.info/.

How do you even know that $35 is not infact the correct price ?

If you disagree with the blockchain.info market data I suggest you take it up with them.


-You did get a working implementation. The code to present the peak price is included in the source. Move the code out of the comment block and you are set.
-It was a php class with example code on how to use the class. You needed nothing more then I deliverd to present the peak price over http.
-It has no known bugs. Your rejection of the blockchain.info data is on you.

I see your attack on the code quality as a pathethic attempt to save face.

I will update https://bitcointalk.org/index.php?topic=147308.0 with payment recived. I will however keep the recomendation not to bid on your offers.

Does the data contain any trades between 31.9099 and 35.0000? If not, I'd say it's pretty certain to be an error. The price jumping from 31.9099 to 35.0000 and then back again to no more than 31.9099 I'd say is highly unlikely. It would basically mean a complete absence of any asks from 31.9099 and up to 35.0000, and and a buyer entering at least $35 as his purchase price (I don't think market orders were implemented on Mt. Gox at that time).

It might be untrue, I haven't actually ran your PHP code, but it's not dishonest - if anything it's an honest mistake.
The reason I wrote that it returns $35 is because my code based on the exact same algorithm and returns $35.
Now, before you go accusing me of bugs in my own code ... the bug is actually in blockchain.info's data ... one of the entries it returns is has price 35, which needs to be manually ignored.

Everybody involved with Bitcoins knows that the price was never over $32.


You know, in software development you can do two things.
A) You can keep the letter of your contracts, and stick to them ... even if you know there are bugs, or the client asked for the wrong thing.
B) Or, you can try actually be helpful to your client, work around 3rd bugs instead of laying blame, and working with clients to improve the spec if needed.

You seem to choose the first approach - good luck with that.
Please don't hesitate not to bid on my offers in the future ... no need to remain angry ... I am not angry with you, as you did save me a bit of time (I could have gotten the same by asking a question on bitcoin.stackexchange for free, but I didn't, and here we are). I hope you're not angry with me, but if you are it's your problem, not mine.

Cheers.

Come on. An easier answer is "it is known". Nobody ever wrote anywhere that bitcoin went above $32.
Another hint is the exact round price of 35.0000 ... the price is never round.

I needed the peak of the bitcoin price, not the peak of the "bitcoin price as returned by blockchain.info".

the site isn't working...

Yeah I know, another bug in the original algorithm, see discussion above about delivering a working product.

The bug is due to reliance on blockchain.info API that only updates once a day (I hope it doesn't update less than once a day!)
This will cause both a delay in the results and inaccurate results.

The API should be switched to something like Mt. Gox API. Maybe this weekend?
I'll post it once it's done.

Thread discussing new all-time high: https://bitcointalk.org/index.php?topic=147475

I agree. The blockchain update rate is too slow for my code to have any real use.

I will update the code to add bitcoincharts and mtgox as data sourses.

Done.

New version with support for bitcoincharts and mtgox is available from http://bitcoin.gdsl.no/bitpeak.zip (http://bitcoin.gdsl.no/bitpeak.zip).

Fixed.


Pro tip: learn and start using github. zips are so 1990.

Could someone please explain why bitcoinpeak.org says $112.25 and not ~$266?

I mean, it's obviously only taking the last X days into account, but what is the value of X?

Yeah, I noticed the problem this week, not sure why it's behaving this way.
It doesn't just take the last X days ... it showed $32 right before the recent peek.

My guess is that the data feed I'm getting is faulty in some way.

Planning to debug it this weekend.

Issue resolved.

The problem was caused by BitcoinCharts API returning only 20,000 records instead of the full range (I don't know if this is documented or not).

I modified the app to save a daily snapshot of the peak price into a database, and take the max of bitcoincharts data and the previous day's peak.

Thanks again for reporting!

Was the exact peak 266.00 or did you just put that in there manually? I seem to recall it being something like 265.95 but I could be wrong.

According to the data in bitcoincharts.com it was exactly 266.

rounding

I entered it manually, if anyone has an authoritative source for the exact peak, please let me know.

I guess I might miss a momentary pick this way (if it peaks between 2 consecutive reads).

Anyway, the current design works, I don't have time to change it (pull requests welcome if they improve the product).

Here's the authoritative source for the $266 peak, Mt. Gox' own data: https://data.mtgox.com/api/1/BTCUSD/trades?since=1365596104182691

Four trades were executed at that price:


For a total of 21.18640495 BTC ($5635.58).

Crap, I checked the service yesterday and it worked ... but now it shows 0 USD peak price for some reason.
I don't have time to debug it right now ... and we're approaching a new all time peak.
