1282  Local / Discussions générales et utilisation du Bitcoin / Re: Bitcoin Anonyme ? - Je reste dubitatif ... on: May 14, 2013, 08:36:26 AM
Utilise ton cerveau 2 minutes ...

Si tu achètes de la drogue sur internet, même en admettant que tu puisses rester 100 % anonyme en utilisant TOR / proxys / ou même un VPS sur la lune, Si tu payes avec ta carte bleue on pourra facilement remonter à toi (nom + prénom / adresse).
Maintenant, si tu payes avec des bitcoins, personne ne pourra jamais retrouver ni ton nom, ni ton prénom ...


Tu pars du principe qu'à la fin on aboutit à un échangeur de type mtgox ... Or tu oublies 2 choses :
1) Mtgox ne vérifie l'identité des utilisateurs que pour sécuriser les transactions et interdire le blanchiment d'argent en euros / dollars. Les envois / réceptions de bitcoins ne sont pas vérifiés, donc le blanchissement d'argent reste facile : tu vends 100 btc contre de la drogue, puis tu échanges ces 100 btc sur mtgox contre des euros, et tu vérifies ton compte mtgox, tu récupères tout sur ton compte bancaire. Tu déclares ces revenus sur ta déclaration d'impôt (autres revenus imposables), tu payes 20 % de taxes et c'est fini... Tu en fais ce que tu en veux.
2) Tout ne finit pas par un échange. Tu peux acheter des trucs avec le bitcoin. Et par exemple si tu veux te procurer un produit interdit aux mineurs (tu as 16 ans) : avec de l'argent et ta carte bleue, la transaction sera bloquée car la vérification de ton âge sera possible. Avec des bitcoins, la transaction sera effectuée et tu pourras accéder au service interdit aux mineurs sans soucis.



En ce qui concerne les services de mixing, tu n'as aucun moyen de savoir qui a envoyé l'argent à qui. Tu pourras voir que X a envoyé de l'argent au service de mixing, ou que Y en a reçu, mais tu ne pourras pas savoir que X a envoyé l'argent à Y. Et quand on parle de X et de Y, on parle bien d'utilisateurs anonymes ... "Use multiple recipient addresses and/or spread the transactions over a number of days to thwart correlation attacks!" ( http://app.bitlaundry.com/ ) = tu peux utiliser plusieurs adresses de réceptions différentes. Exemple : tu voles une adresse bitcoin avec 100 bitcoins dessus. Tu te crées 10 adresses bitcoins différentes, qui sont donc vides pour l'instant. Tu utilises le service de mixing pour envoyer les 100 bitcoins volés à tes 10 adresses bitcoins nouvellement créées. Tu n'envoyes pas la même quantité de btc sur chaque adresse (par exemple 50 sur l'adresse 1, 20 sur l'adresse 2, etc...). Tu étales les versements sur 1 mois. Au final on pourra voir que l'adresse qui a été piratée a envoyée 100 btc au service de mixing. On pourra également voir que tes 10 adresses ont reçu de l'adresse du service de mixing, mais impossible de faire le lien, car le montant des transactions est différent, et que l'étalement des envois sur 1 mois rend tout traçage impossible (entre temps il y aura eu des milliers d'autres transactions dont les montants pourraient correspondre).

Maybe you should starting using your brain for once. If bitcoin is used and adopted globally it will be worth far more than $5000 let alone $500, it's a mathematical certainty if you accept this premise. Even if only 10% of the human population would have $500 worth of bitcoins to work with 1 bitcoin would be valued at about 32,000 usd. And that's only considering a small scale of adoption where our old currencies would still play the dominant role in this world.


You are either stupid or american, or maybe both.
10 % of human population is a small scale of adoption? Only 30 % of the human population is connected to internet. 10 % is way over a small scale of adoption...

+ your calculation is over-evaluated. The number of bitcoins will double up, the value for each one will be half of it.
+ the real important factor is "how much some average guy is up to put on 1 btc" which is not going to be over 1k usd.


You wrongly assumed that bitcoin might/will/could be/should be handling an over-estimated part of the transactions... But it's not.
Notwithstanding the fact that 22.4 % of the world population is living with less than 1.25 usd a day ; almost no one will pay 1k usd for something that can disappear or lost its value any day. The most important factor is not which market bitcoin can reach (which will not be even close to what you assumed), but the psychological value of 1 btc.
1285  Economy / Trading Discussion / Re: Forex broker plus500 has opened for Bitcoin trading. on: May 13, 2013, 10:05:36 AM
Is there a catch in the 25 euros bonus with no deposit requirement?


you have to register personal details and phone number verification is mandatory.


You also have to trade that amount of money in order to allow the broker to win effectively more than the 25 euros they gave you in order to be able to withdraw it, which is unlikely that anyone is able to withdraw it without making a deposit or being lucky.
1286  Economy / Currency exchange / Re: Selling BTC Mtgox Last +5% Skrill / Pokerstars / Moneygram / WU on: May 13, 2013, 09:55:31 AM
It will take 1 or 2 business days to proceed ... Who on earth will be so hurry that he can't wait that long?
+ you don't have to pay any commission when you are only buying btc, and not selling them ...
+ you can find some exchange with lower price than mtgox.
+ I replied cause I was so shocked that you offered that


Still, good luck with your trade. I hope you will find any fool to buy that  Huh
1287  Economy / Currency exchange / Re: Selling BTC Mtgox Last +5% Skrill / Pokerstars / Moneygram / WU on: May 13, 2013, 09:46:09 AM
Why would anyone give you mtgox +5 % when they can get mtgox + 0 % for free?
1288  Economy / Service Discussion / Re: Is Plus500 the only platform that allows traders to short bitcoins? on: May 13, 2013, 09:44:59 AM
plus500 is not dealing with bitcoins. They just allow to trade and speculate about the mtgox price. So, it does not impact the price, since it does create any order on the market.

ripple is not a scam. 

What does it have to do with my message? Huh.
1289  Economy / Speculation / Re: What price do you see Bitcoins reaching? on: May 13, 2013, 09:43:20 AM
Infinity.

It is a mathematical certainty that 1 USD in its present incarnation will be worth exactly 0 ounces of gold and 0 BTC at some point in the future.


Except if the usd disappears that's not even possible...
1290  Economy / Speculation / Re: What price do you see Bitcoins reaching? on: May 13, 2013, 09:42:22 AM
Would be around 500 dollars / btc.

I hope you are trolling. I hope this entire thread is trolling.

If the U.S. dollar was replaced by Bitcoins the value per Bitcoin (in terms of current purchasing power parity) would be millions.


Bitcoin will never be closed to 10 000 usd, start using your brain.
It is still unlikely that we will see 200 usd again this year.

USD being replaced by bitcoin is not even conceivable, but if bitcoin somehow is adopted, which is highly unlikely, the value will be around 500 usd / btc.

Sachant que bitcoin-central est egalement "paytunia.com", peut on un jour:
1) espérer un réponse de leur part quand on envoie un mail a propos de paytunia?
2) espérer un jour avoir de nouveau accès aux bitcoins qui sont hébergés dans le wallet paytunia ?

Des réponses claires sont également attendue..... enfin s'il y a vraiment une personne de bitcoin-central pour y répondre

1) non
2) oui
