Does this mean that if I were to deposit 10 BTC today, and let them sit there for one year and then withdrawal them after a year, they will be more 'mixed'?
If someone where to try and follow your coins, they see you move 100 BTC and suspect you put it in a mixer. They would then not be able to follow those coins to find out where you withdrew it, they would need to go check all bitcoin transactions and see if they find a transaction of 97-99 BTC in a block after the transaction. 97-99 is within the 1-3% service fee i take. Every hour there are approximately 10-15 000 transactions, some of them are between 97-99 BTC, after a day there should have been enough transactions on the bitcoin blockchain within that range that they cant know which one is yours or if you even withdrew yet or not. To make it harder for them to guess which transaction would be your withdraw its a good idea to withdraw to maybe 2 addresses and with randomized amounts and long randomized delays.
Can you tell us a little bit about what sort of cryptographic solution you use to track every sincle coin and fraction of a coin that a user has originally owned so they will never receive it again?
No
Can you tell us some statistics about what the maximum length of time a single coin, or fraction of a coin, has remained on the tumbler before finally being tumbled out?
No I wont tell you, but it depends on the amount of coins in the mixer wallets and the volume users make. Higher volume (deposits/withdraws) and a lower amount of coins in the mixer wallets would make the coins move faster, stay shorter time.
Do you mean to say that if User A deposits 1 BTC into Deposit Address A, that User B who withdrawals 0.5 BTC will receive half of the 1 BTC from Deposit Address A? Is this the minimum amount of tumbling?[/li][/list]
No. The minimum amount is 0.001 BTC right now, the information about minimum amount is on the quickmix page and the withdraw page if you use registered account.
I asked about how often the 'QUICK MIX' withdrawals are made and at what times of day. You stated on your website that they happen 'four times a day'. Does this mean it's the same four times a day; i.e. 0636, 0911, 1758, 2325? And each day is the same time, or each day is a different time of day?
Can you point me to where it says that quick mix happens "four times a day"?
Quickmix creates your withdraw directly after your deposit is added to your balance, there is no delay except if you specify one when creating the quickmix.
What about a coin that later returns to the tumbler, because another user has brought it back?
As I explained in my previous post about this, the system does a taint analysis on all deposited coins to see if they have previously been on Bitcoin Blender to take care of this problem.
Are you saying that your tool is effective and your tumbler uses this tool? Would you be willing to open source this tool?
Correct, I have been thinking about making the taint analysis tool available on the site, as a way for users to verify that the new coins they received has no taint to the original coins but it would be better if it was provided by a third party instead of me.
https://bitcointalk.org/index.php?topic=436467.msg46285715#msg46285715What method would you suggest to pass through 100.000 BTC through your tumbler, or other tumbler also?
Mixing 100000 BTC? It's going to take a long time. I suggest reading the Best-Practice Guide that is on the front page of the mixer, "Delay your withdraws" and "Withdraw to Multiple Addresses".
Finally, can you tell us anything about how your service is hosted? I'm confused as to how you have a clearnet detached from the onion. Does this mean your clearnet has absolutely no link to your onion? Different hosting providers, different countries, and different server architectures to prevent fingerprinting and surely different TTPs to administrate them both?
The clearnet site uses a different hosting provider, registered anonymously. There is nothing linking the clearnet site to the hosting provider used for the mixer.
