Topic: bitcoin-app.com - Facebook Bitcoin App - 0.01 BTC welcome present - page 2. (Read 5524 times)

It was not a scam, merely a negative balance due to technical difficulties that was fixed swift and quickly. I am continuing to use this facebook app and it is a great online wallet for those already with a Facebook account.

EDIT:to remove the Libel against YouGotCoin

It uses the original bitcoin client and makes no special tricks with your password.
The whole authentication process is entirely handled from Facebook.
We have no access to your password, it is submitted directly to Facebook and never to the App.

Does the app have access to everyone's private keys or does it use scripting with password or something to make keys and sign tx messages?

Indeed, actually any Facebook app can see the basic info of any Facebook member without anybody has to grant permission.

BTW: The withdrawal granularity is updated to 0.00001 BTC now (was 0.01 BTC before).

I don't know anything about the internals of facebook app development; but to my mind there is only one bit of information necessary for a bitcoin app on facebook: a link to the account.  Preferably in the form of some numeric ID.

That's enough to identify me next time I come a knocking on the app's door.

Then I'd allow the following permissions: notify me of a balance change on the associated bitcoin address.

My email address is definitely not needed.  Facebook has a notification system.

I understand that most facebook users are privacy-fools and don't give a rat's ass about what they hand out; but it makes us look like hypocrites when bitcoin apps remove the very features that make bitcoin so attractive.


You don't "need" my name.  Facebook ID -- okay.  Language -- okay.  "the list of your friends" -- WTF?

Perhaps I've not understood the point of this app.  There is little point in it just being a bitcoin interface... there are already wallets online and pasting a bitcoin address to my friends is not difficult.  Presumably then the purpose is to make it possible to deposit some bitcoins "on facebook"; and then use them to buy things -- either from other app providers, or from someone with a bitcoin address.   I'm afraid I don't see why either of those things requires knowledge of my friends list.


That's not unreasonable.

My guess is that a lot of the lack of privacy is nothing to do with that apps themselves (as you say "basic info" is minimum), it's that facebook don't care about protecting me and will hand over more than I want to any app.

For the paranoid like me, that unfortunately means -- no apps.

A good point. The answer is easy: There is just no way to write a facebook app without asking for the basic info. It's exactly that what you give in public to all the other Facebook users on Facebook.

bitcoin-app.com uses: Your name (to talk to you), your Facebook-ID (to connect it with your bitcoin account on bitcoin-app.com), your language (for translations in the future), the list of your friends (to show it to you).
Additionally we ask for your email (that is special) for the simple reason to contact you in case Facebook e.g. closes the app because they might don't like bitcoins. We would have no way to give you your coins back if we would not have your email.

Concerning yougetcoin:
I agree with you. I really don't know what yougetcoin wants to do with your birthday. Makes no sense to me. And they want even more! Ones you grant the permissions you quoted above, they require another heavy weight permission: to spam on any wall (those of your friends and others) literally what ever they want in your name. That's what I would never grant to any app...

It probably doesn't, but it's being used a lazy Open ID system, and without some kind of a hash of your identity based off some kind of unique identifying information, you can't have an account set up automatically.

It's pretty standard to use facebook or OpenID cousins to login to a sites. I've written a few myself too. Basically it's just used to differentiate you and me when we both go to the website. Nothing more.

What is wrong with the people writing these apps?



Why on earth does a bitcoin app need access to any personal information whatsoever?

Are the authors just hoping that because its facebook, people won't care about their privacy?  Possibly not; but to get a foothold they've got to get their apps promoted by existing bitcoiners to their facebook friends.  There is no way in hell I'm going to recommend any app that asks for more information than it needs to operate.

yougotcoin: fail
bitcoin-app: fail

You can send coins to any Facebook member, not only to your friends (see the search button)

Thanks!
Well, let's first see if it can sustain itself with bitcoins. Currently looks good. We got about 70 users in only 3 days.

Can you make a Facebook Litecoin App??
I'll donate...
Awesome work!

Perfect. Hope you liked it.

Great. And believe me, I hope that too

Thanks, I've just sent 0.01 BTC to my friend, hope he'll claim that

So, everything is correct here.

One of the about 5 lines of text the bitcoin-app prints on the screes says "(rounded with granularity 0.01)".
Your withdrawal amount  0.00945 BTC is thus rounded  (correctly) to 0.01 BTC with granularity 0.01.
That should explain all the rest of the output you got.

Really ?

"You wanted to send 0.010000 BTC and have to pay a withdrawal fee (0.5%) of 0.000050 BTC and a BC fee of 0.000500 (total 0.010550 BTC) but have only 0.010000 BTC!" when I want to withdraw 0.00945 BTC.

What is the deal

When I try and withdraw 0.0009 it still does not work and I get a blank page.

Definitely looks damn broken to me ...

It's definitely not broken. You should read the messages you get presented carefully.
Have fun with it like all the others!

And thanks to all the others! So many users in just 2 days. I'm excited!

Broken. Cannot withdraw anything.

Don't waste your time folks. Move on.
