As an anonymization service we try to make it possible to pay for premium accounts anonymously.
One can buy prepaid cards at a lot of newspaper stands, gas stations and supermarkets anonymously using cash. In Germany there is a limit of 100 €/month due to the Gesetz über das Kreditwesen (Banking Act).
JonDonym offers European users and North Americans the option to pay anonymously via paysafecard cash codes. Outlets selling paysafecard cash codes close to you may be found with the "Find sales outlets" search on the website of the provider. In order to a guarantee a smooth and anonymous deployment of cash codes you should consider the following advices:
Buy cash codes which fit to the premium rate you want to purchase for one-time usage. It is not possible to use more than one cash codes for one payment.
Refrain from checking the cash codes before using them. Use the codes immediately for your JonDonym premium account after purchasing them. Due to restrictive security settings cash codes are blocked automatically if they are entered from more than one IP address.
Use JonDonym for the payment. During the payment both paysafecard's website and the webshop of JonDos GmbH are accessed. In order to avoid a deanonymization by means of your IP address reliably we recommend using JonDo + JonDoFox for the payment. There are no constraints regarding the mix cascade you may want to use.
If your cash code got blocked automatically, please write an email to the support of paysafecard. If you provide a copy of that cash code you will get a new one which is unblocked.
Bitcoin is a digitial peer-to-peer currency without a central and administrating institution. JonDos GmbH is accepting Bitcoins as payment for premium accounts.
Without proper precautions paying with Bitcoins is not anonymous. All transactions are saved in a publicly available "eternal logfile". Researchers of the Darmstadt University of Technology have provided an analysis of Bitcoin's anonymity on the Chaos Communication Congress 2011. Another analysis was published by D. Ron und A. Shamir. They were able to identify the IP addresses of users and link the different Bitcoin addresses of an account. For an example informations about the Bitcoin usage of Wikileaks were published. Until March 2012 Wikileaks used 83 Bitcoin addresses and got 2605.25 BTC from supporters.
As Bitcoin relies on exchanging data over the Internet you may use JonDonym in order to stay anonymous during Bitcoin transactions. Thereby, two separate problems need to get solved:
You may use JonDonym to stay anonymous during Bitcoin transactions.
If you didn't trust a third party server, you may use the bitcoin client Electrum to keep all your bitcoins and cryptografic keys on your computer. The usage of Electrum requiered only small amout of data traffic. The program does not download the hole blockchain, it uses remote servers for most work. You can stay anonymous by using Electrum with JonDonym premium services. Start the program with the following proxy parameters:
electrum --proxy=http:127.0.0.1:4001You can buy Bitcoins by cash or send cash by snail mail without bank transfer and without leaking identificable informations to the Bitcoin seller.
If you buy virtual goods like JonDonym premium coupons you can pay it anonymously with Bitcoins. If you buy real world goods keep in mind you have to give out a shipping address which may compromise your Bitcoin account. Do not use an anonymous Bitcoin account for this purpose. Create a new account and don't link both accounts together.
