Un grand merci a vous deux... Et lien bookmarké pour les longues soirées d'hiver (c'est-a-dire maintenant quoi ; )

Hey all,

here's my first experience with Ripple... All I want is to start using it. So I create an account on Ripple. I have already a fully verified account on Bitstamp with money on it.

I want to send 0.5 BTC to Ripple or so from Bitstamp. And there I learn that I need to "Trust Bitstamp" and that it's going to cost one XRP (maybe I misread but still). I ask on IRC and someone helps me and lends me 20 XRP.

Going back to Ripple, I want to trust Bitstamp: sorry, you need 25 XRP for that (I think it's the first time I read about 25 but anyway...). So I explain that and ask for 5 more: at this point the person thinks I'm trying to scam him from 5 more XRP.

He sends me 5 more and I trust Bitstamp. Good. I can send some BTC to my Ripple wallet.

Now before giving back the 25 XRP to the person who helped me, I think "oh oh, wait: if I sent you the 25 back now, I may not be able to do anything more on Ripple, because XRPs are apparently needed for nearly everything". So we agree that I'll first transform some of my BTC into XRP and then sent him back his 25.

I place an order to get 398 XRP for 0.01 BTC or something like that and then...

"You need 30 XRP to do place an order"

The "word" that comes to mind is "Catch-22".

Creating an account and not being to establish trust with one the biggest bitcoin exchange is weird. Not being able to trade for 300 XRPs because you don't have 30 XRPs is even weirder.

I'm sure there are lots of goods reason for this and lots of free XRPs around but making feel newcomers who like beggars ain't nice.

I'm not even asking for the 5 XRP that would allow me to reach 30 and hence place that order to trade BTC for XRPs... I'm pissed off.

I really think that this thing should be made more friendly to newcomers. Why not give the first 25 XRPs you need to establish your first trust to a known exchange and then take them back later?

Same for the first trade to XRPs.

Maybe I missed the obvious way to do this but all in all a pretty bad experience.

Too bad because the site looks kinda good and Ripple seems convenient once you're set up.

EDIT: apparently you can buy XRPs directly on Bitstamp then send them to Ripple but... On Bistamp it says: "We have no Ripples at the moment. Please try later"... Then, still in Bitstamp, I don't see the option to send Ripples to Ripple (but maybe it's because I've got zero of them).

There are know documented waves much bigger than that:

http://en.wikipedia.org/wiki/1958_Lituya_Bay_megatsunami

However if even a tiny wave like the one in that Photoshopped picture had hit a big city like the one in the picture, we'd all know.

It's one of the major risk for the U.S. east coast btw: there's a mountain in some Canary island (it's in non-continental Europe) that could see a gigantic landslide one of these days. If it happens, a 300 meters high wave would reach and destroy New-York in eight hours and pretty much the entire east coast of the U.S 

From what I read here Coindesk had also been advocating inputs.io as one of the most secure site ever if I'm not mistaken... Despite numerous people pointing out here why inputs.io wasn't the be-all end-all of security.

So I'm not exactly sure Coindesk is the epitomy of journalistic integrity.

And it's kinda bad that a single site, with a single rumor, no matter if it turns true or not, can have a -25% instant effect on the btc value 

I'm not saying they're not correct: but I'm taking it with a grain of salt.

"le linux n'exécutant rien depuis la clef"

Quel Linux et configuré comment ? Il y a eu divers problemes de sécurité lié a l'auto-run sur Linux et de nombreuses pages (notamment ici-meme sur bitcointalk) expliquent comment désactiver l'auto-run des clés USB sur Linux non !?

(je n'y connais pas grand chose a ce sujet mais je préfere etre prudent)

Bonjour a tous,

je me suis procuré le fichier Bash de grondilu ici (est-ce bien la bonne addresse ?) :

https://github.com/grondilu/bitcoin-bash-tools

et je lance ensuite newBitcoinKey et j'obtiens, par exemple :  (wallet que je ne compte pas utiliser bien évidemment)


J'ai a présent quelques petites questions  

Je ne comprend pourquoi le "compressed" WIF fait un caractere de plus que le "uncompressed" WIF et je ne comprend pas pourquoi la "bitcoin address" fait la meme taille dans les deux cas ("compressed" et "uncompressed").

Si je venais a poster le WIF publiquement, n'importe qui pourrait me voler ce qu'il y a dans mon wallet ?

Le 'X' et le 'Y' donne les coordonnées du point de base sur la courbe elliptique définie par le "secret exponent", c'est bien cela ? Si oui, il y a-t-il un et un seul unique point de base pour un secret exponent ?

Enfin je ne parviens pas a utiliser le vanitygen : quoi que j'essaye il met "unexpected format for public point". Ou se trouve ce "public point" et comment l'utiliser ?

Un exemple de ce que je fais mal :


(edit: je pense que la "uncompressed public key" est simplement 04 + X + Y, qui donne 130 caracteres / hexdigits... Maintenant il me reste a comprendre comment créer la "compressed public key")

So much condescension in so few words

I opened the account first then realized I needed to scan papers... No scanner here so I only got my scans 3 days later.

From the moment I uploaded the scans on Bitstamp.net it took me 3 days to pass from "PENDING" to "VERIFIED".

I'm now waiting to see how long a deposit (using EU SEPA wire transfer) takes to reach them (not too much money at first: nothing that I cannot afford to loose).

Wouldn't you waste less time making a list of the coins you believe aren't scamcoins?

Does anyone know which percentage of their bitcoins Bitstamp is keeping in cold storage?

In case of an inputs.io-like SNAFU, which % of your coins do you think you'll see back?

Also... When an exchange like that get owned (as obviously happens once in a while) and see their bitcoins stolen, will they use your account balance in EUR / USD to reimburse everybody?

(btw I opened an account there and scanned my driving license and an utility bill and I'm now verified)

Is it possible to set up a totally offline 2FA using something like Google Authenticator or another "widely" used authentication method?

For example my bank has a "digipass": a physical device without any network connection (no LAN, no WiFi, no bluetooth, no nothing) that generates codes in response to challenges (bank account number to wire money to, transfer amount, etc.). Or some companies have physical RSA tokens for their employees which permanently generate authentication codes. PokerStars also offers such a fully offline 2FA device (obviously some players have a lot of money in their PokerStars account).

But in the Bitcoin ecosystem apparently we're stuck with 2FA which apparently require a device which is always connected... I'm not saying it entirely defeats the purpose of 2FA but there have already been reports about people getting their bitcoin stolen despite having 2FA.

In a way all these "2FA apps" are really a poor-man's 2FA compare to these fully offline devices. I mean: there's a very real issue that the device offering the 2FA app gets itself remotely compromised (say your Mac is compromised and you use that same Mac to log to your bitcoin exchange and to "sync" your smartphone... Smartphone which you use as a 2FA       I mean: I'm not the only one to think that it's only a matter of time before bad guys find a way to exploit this right?!).

So... In the same way that it is possible to use an offline computer to generate a wallet that you can put in deep cold storage, is there a way to somehow setup a device (an Android device ?) to use something like Google Authenticator but entirely offline?

I don't mind if the device is only used for 2FA... But I do mind if it has WiFi, bluetooth, or anything making it possible to be "online".

Hey all, super newbie here...

I'm not using Ripple yet and I'm not sure I plan to after reading what people here have to say about it. Yet I'm genuinely curious about it and I've got a question...

Can Ripple be used to buy LTC from BTC without having XRP involved in the process? Or is the "small fee" always paid in XRP?

Also, if I don't really "trust" Ripple to put all my eggs into and have no faith whatsoever in XRP, can I still use Ripple to, say:

- transfer a tiny amount of BTC from Bitstamp to Ripple
- exchange the tiny amount of BTC into another crypto currency at Ripple
- transfer the new cryptocurrency to my wallet(s)

How long would that take?

Basically I take it that my question comes down to: even if I don't trust Ripple much, can it still be useful to convert and move small amounts to/from different crypto currencies? (hence never being exposed too much to Ripple being a scam or getting owned by the feds / DoJ or hacked or anything else that could happen to the centralized dot com server).
