Topic: bitcoinparty.co - bitcoin prices comparison in Europe & US (Read 501 times)

Great website! I think it could offer a few more features though, for example a List of the best crypto exchanges for example?

Oops, good spot, thanks! Sadly, it's a manual process for now, except the live rates and fees (depending on the API features for each provider). Fixed now!

Re Europe-only question - it's simply due to priorities, already working on US and other countries/regions will follow.

Cheers!

It looks good, but why only limit it to Europe? Not sure where you based everything from, but I randomly checked a couple of things on the list and both had inaccurate data ^{[e.g. there's "DCA in Binance" and "Kraken supports lightning" transactions]}.

It looks much better now but I would also add something like filter that would show and hide only exchanges you can use to buy or sell Bitcoin without kyc.
Maybe you could add more filters for countries, privacy, fees, and lightning network, or think about including Bitcoin ATM locations in your list.
You could consider checking exchanges from kycnot.me website.

Hi, after a while of no development I picked this back up to add some more features and work on the content a little bit.

Just popping in to possibly get some feedback on a new view I've built to fairly quickly compare features of exchanges available in europe at https://bitcoinparty.co/buy-bitcoin-in-europe

Thoughts welcome!

Evilish, had a quick look at Gemini fee schedule and how we calculate them and it looks fine at first glance, do you mind elaborating a bit on the "offness" of their quote? If you prefer, feel free to DM me here or on twitter (@bitcoinpartypl).

Cheers!

For each request we fetch live rates from all the entities we compare, so is it likely that the price moved between your two requests?
There's no logic based on the IP address or other client metadata from the request.

We switch locale based on the domain visited, so when you visit bitcoinparty.co you'll end up on an English version of the site with default currency set to EUR and when you switch URLs to bitcoinparty.pl, you'll get the polish version of the site with PLN currency.

Regarding the DCA comment: there is an "Auto Buy?" column in the results that indicates entities that allow you to set up recurrent buys (aka Dollar Cost Averaging).
Also, Lightning Network withdrawals indicator is coming soon (at least Kraken & Paxful are to enable LN in the near future, OKCoin already providing this, soon to be listed).


* Will try and add Coinbase PRO asap and post an update here. This is a sideproject, so a bit time restricted.
* Also will double check Gemini fees & parameters. As mentioned before we're checking live rates, but fees mostly are hardcoded, based on static pages with fee schedules on respective exchange websites, unless an entity provides fees in their quoting API. So for the static ones, it's a constant struggle to keep up with any potential changes on their side.
* The final amount takes into account all the fees including onchain transaction fees for withdrawals from exchanges (if applicable).

Thanks for taking the time to post your questions and observations here!

Great work bitcoinparty_pl. I like the website. It's nice and simple to use.

Just a few observations. I don't see Coinbase Pro in the list of exchanges when I pick USD. That is where I make most of my purchases and sales, so quite a bummer not being able to compare the quotes there with other exchanges. And fees for Gemini look a bit off (unless it's showing Polish fees and not US fees, in which case I am probably wrong).

Also, is the amount that you show in "You'll receive" before or after the fees have been deducted?

Hi, just popping in here to let y'all know I've added HodlHodl to the list of compared exchanges. More brokers to come in the upcoming weeks.

Have a fun & productive week!

Hi, just FYI, the reported bug has been fixed. Thank you for taking the time to click around, highly appreciated.

Thanks a lot! Will investigate shortly!
It's most likely not the case of broker api being inacessible as then the result is not being included in the response at all.
Likely a mishandled case in the backend as Insanerman suggested.

I think it has an error in processing the API from swaply which then returned a null value of 1 BTC = 0 euro then had computed on the backend the swaply fee and your EURO amount which then returned a negative value indicated on your screenshot. But there are another possibility, and it might be the swaply's API being inaccessible the time you've encountered the problem. Those were just my ideas

It seems that you are making this project waaaay bigger than I expected. Keep this up dude! I'll try to see other bugs as well to help impprove your system!

I think I found a bug while using small amounts for the "BTC > EUR" pair ^{[swaply keeps giving negative amounts up until 29 euros]} and on top of that if I use the least possible amount ^{[9 euros]}, it keeps showing as a recommended exchange for that pair ^{[I believe those shown with a light green background are considered best in each table]}: SS of the bug
^{- Noticed a similar behavior for the PLN pair as well [SS for Flyingatom and Bitcantor].}

• If for some reason it's not a bug, then you should probably consider delisting those exchanges that return with negative results.

Hi, just a quick update:

* changed the jQuery CDN from googleapis to original jquery.com
* added Localcryptos.com p2p exchange
* added a simple currency-to-sats calculator at https://bitcoinparty.co/sats.

Thanks again for the feedback

Good looking website but I think you need to add more websites and exchanges to make it even better.
For example you can add localcryptos.com as a non kyc peer-to-peer alternative for localbitcoins and paxful:
https://localcryptos.com/

I also wish we had more decentralized exchanges like Bisq or better :/

Thanks for the feedback


lol

Re googleapis used to fetch the minified jquery library: the answer really depends on what we mean by "tracking" exactly, but G will see that request for this resource on their servers, yes. I'd argue it's still much more benign than using analytics, tracking cookies, etc but there's really no reason for this other than convenience in the initial implementation, so this is definitely something to address. Will remove shortly (tbh this was on the todo list for quite a while now). Good catch though!

Re monetization - thanks for your suggestions. There are a couple affiliate links already on the site for brokers and exchanges that have an open process of applying, but some companies require the traffic to be substantial to join. I'd like to focus on significantly improving the product first, but ofc this one of the most obvious way to monetize the site in the future.

That JQuery API is used only for the front-end elements, particularly on handling events and manipulating it on the website -- the way how they receive the price input of the user and how they show the results. Apparently, they've used the google API so that the user would just use an online jQuery file than getting it from the website's server, but using it doesn't really tracks you down. And yes, Google API's for some front end development (such as using online Google fonts) never tracks any user, but rather just sends data without receiving one.

I like the idea of the project. However, just like Vod's have mentioned, you can use referral links to have at least a little monetization to your platform, or you can have 2 options where they can choose one with ref link or without (for a better user preference). And I would also like to suggest to add more supported exchanges. For the front end, there are other ways to visualize results that would fit  for a better user-experience, but yours doesn't really need a change at all. Good job!

I like it.  First legit project of 2021!  There is also some room to monetize with referral links on the websites - wouldn't interfere with the user experience at all.  

Edit:  Your site says you value privacy.   Can't google track you with this?

Hi all,

I'm building a bitcoin price comparison website and I'm looking for feedback from the community.

It launched several months ago solely for Polish market but I've translated the site since and onboarded more brokers and exchanges that support EUR and USD.

The project is available at https://bitcoinparty.co/ (we're a "bitcoin only" endeavor).

In the near future I hope to onboard more DCA-enabled brokers and possibly expand outwards to compare other bitcoin related products.

Any feedback would be much appreciated, even if it's simply answering a question: do you find it useful? YES/NO/Don't care, that would help a lot

Happy to answer any questions, etc.
Cheers & Happy 2021!
