Thank you very much ajaxmoor for your answer!  

If you buy and sell bitcoins in an exchange like bitstamp, you only have a small yield;
but
if you invest in a binary option like btcoracle.com, you can receive 50% for a small variation of the price, and
if you invest in market.com you have a leverage of 20.
These two last exemples show how you can make fast money (But I know that there are risks).

I am looking for other websites with a larger leverage or something other with a large (potential) yield.

Hello everybody, :-)

Please, do you know something better than market.com (with leverage ×20) in order to earn money (or bitcoins) on bitcoin price variations?

Thank you very much, but we don't know how much percent the transaction fees are...

Hi everybody,

Do you understand what kind of transaction fee there is at ANXBTC?
It is possible to read in the FAQ:
"ANX customers are no longer charged transaction fees when using the ANXBTC platform to buy and sell bitcoins. The price displayed for buying and selling bitcoins via ANXBTC is determined by the members of the ANX Open Dealer Network who are actively participating at the time your order is submitted. The price displayed is the total price and your account will be credited and debited as per the details provided on screen. There are no additional or hidden fees. Deposit and withdrawal fees still apply and can be viewed via the Funds Management screen."
and
"Transaction fees are deducted from the received amount."
but nothing else.
It looks strange.

Sie möchten, dass ich Ihnen etwas klar darstelle und wenn möglich mit screen shots.

Ich wurde (hoffentlich) nicht betrogen.
Habe mich schon bei bitcoin.de gemeldet.
Bin nur sehr erstaunt.

Bonjour tout le monde,

bitcoin.de a changé la liste de mes achats.
Certains achats ont changé de date, d'autres ont disparus.

J'ai régulièrement sauvegardé la liste de mes achats et je constate aujourd'hui que la liste actuelle ne correspond pas à celles que j'ai sauvegardées.

C'est comme avec MtGox, on ne peut faire confiance à aucun site.

D'autres personnes ont-elles faite la même expérience ?

Hi everybody,

bitcoin.de changed my history of buys.
Some buys have new date, other buys disapeared!

I made several copies of my history of buys. Now I notice that some copies of my history do not agree with the present history.

Did  someone also noted that?

Would it be a forerunner indicating that bitcoin.de is the next MtGox?

Hallo Alle,

bitcoin.de hat die Liste meiner Käufe geändert.
Manche Käufe haben neue Daten und andere Käufe sind verschwunden!

Habe immer wieder Kopien der Liste meiner Käufe gemacht.
Nun stelle ich fest, dass die jetzige Liste nicht mit der, die ich kopiert habe, übereinstimmt.

Es ist genau wie bei MtGox, man kann keine Webseite vetrauen.

Hat jemand die selbe Erfahrung gemacht?

Hi Shorena,
Thank you very much!
