- obayesshelton 13y agonothing loads for me in Chrome either that or it is taking an age.
- cjm 13y agohrrm, ok, i'm watching it -- everything is loading fine for me
- snitko 13y agoCan kinda confirm. Took 1 min to load background color (!) at first, then nothing else loaded. On a second attempt it seems to work.
- seferphier 13y agoworks well with the latest version of firefox
- robotmay 13y agoTakes a while to load (Firefox Dev) but it's really nice when it does!
- cjm 13y agothanks :)
- limmeau 13y agoMtGox at $90 and BTCe at $83. Easy arbitrage money? Probably not, but why not?
- nazgulnarsil 13y agotransaction fees and liquidity.
- conjectures 13y agoLooks that way - which says something about the maturity of the bitcoin system.
- netcan 13y agoLooking at it another way. Considering the maturity of the bitcoin system, it's amazing how much attention and money has gone in.
- shawabawa3 13y agoI tried but it was too much effort. All the api's are unreliable, it's hard to tell if your order went through, if it did you have no idea how long it will actually take. Then, once you've run out of money on one of the sites you have to go through the expensive and lengthy process to get more on, and you have to go through the same again to actually withdraw. It ends up just not being worth the time
- rfnslyr 13y agoActually I was planning on writing something of an arbitrage bot. It's hard though, I don't have any technical analysis knowledge. However, I did make over a grand on BTCe just buying and trading between LTC, BTC, and USD, and other small numbers that used to get "pumped". Quite fun.
- abrkn 13y agoI haven't had time to polish these, but would be interested in collaborating with someone to make something robust. Automatic trader: https://github.com/abrkn/margin https://github.com/abrkn/margin Common interface to several exchanges: https://github.com/abrkn/hail https://github.com/abrkn/hail Margin would be very nice with more tests and state.
- tudborg 13y agoChrome 28.0.1500.71 OSX, works ok. A little unresponsive sometimes. Really cool. I trade in EUR though, so it would be nice with a mtgox EUR listing. The access rights it wants to my twitter account is unacceptable though, so no chance i am going to bind my account to bitjoy.
- cjm 13y agoCool, more currencies coming soon -- will look at the permissions. Thanks for the feedback.
- frankacter 13y agoLooks great (FireFox v22), loaded after 45 seconds. Can you give some specifics as to what the tech is behind BitJoy and what your plans for it are?
- cjm 13y ago45s is waaaay too long :) will make that better. The goal is to create a real-time snapshot of the bitcon ecosystem & to build context around the data so it's simple to consume and understand. Price was a logical place to start, hope to add more types of data in the future.
- maaaats 13y ago4-5 seconds in FF here.
- cjm 13y agoAs far as tech it's node + engine.io + backbone. I can go into more detail though if you have any questions. Also check out, https://github.com/socketstream/socketstream https://github.com/socketstream/socketstream
- thomasjames 13y agoLooks really good. One thing to point out that is probably a one-line fix: the month being displayed for news articles is exactly one month before the actual date they came out.
- cjm 13y agoHrrrrrmm :) thanks for spotting that.
- plg 13y agoso here's a naive question : why aren't people simply playing off the price differentials between mt gox, bitstamp and btc (more than $7 when I just opened the OP's page) and making a ton of money? or maybe they are? or maybe commissions / fees are so high they eat up any profit?
- askmike 13y agoYep, it's pretty hard and slow to move the money around (in and out of the exchanges) and all the fees eat away almost all profits.
- TomGullen 13y agoBuy 10 BTC at btc-e.com for 831.66 USD Sell on MtGox for 591.18 GBP = 901.73 USD (my account is set to GBP) That's 70.07 USD profit from 10 BTC, or ~$7 USD per bitcoin traded. Seems like a good opportunity. The problem is you can't cycle your money quickly, it takes time to sell bitcoin for cash and withdraw it ready for the next cycle. But I mean there's the potential to make ~8% on each cycle. Buying, transfering and selling should also be a fairly quick process so you're not exposing yourself too much. I think as soon as instant cash deposit/withdrawls are available through various exchanges these gaps will close up pretty fast.
- simondlr 13y agoYou can also play arbitrage between altcoins (BTC to LTC, or LTC to XMP, or any other). On Vircurex, Cryptsy, BTC-e, etc. Even with liquidity being lower you can see them being rather close on the different exchanges.
- jjsz 13y agoDo you know of an economic or finance course that can help me understand how to use Bitcoin or any other currency. There's all the articles explaining Bitcoin but none treating it like a foreign currency and teaching how to apply foreign trade. I'll just search foreign trading at the library in the mean time...
- jonahx 13y agoLoaded slowly, but really nice UI imo. Nice work.
- cjm 13y agoThanks -- will work on the initial load time.
- csomar 13y agoIt crashes Chrome on the iPad.
- chrisvineup 13y agoAny plans to add other cryptocurrencies? Litecoin etc?
- cjm 13y agoYeah, possibly -- focus will be on filling out bitcoin data and other currencies first though.
- mhidalgo 13y agoLooks great ,would love to talk more about it , what's the best way to reach you?
- cjm 13y agothanks, cjm712 -at- gmail
- _feda_ 13y agoWow what a great interface. Really great clean design and I like the fact that you've used two seperate btc exchanges. I think this tab will be pinned in my browser once I begin my new career as a bitcoin dealer on localbitcoins.com ;)
- ca98am79 13y agothis is cool, but it would be great to also see volume
