Access to Bitcoin Fog

You should install Tor browser. Tor is an open-source anonymization network.

For easy setup: Tor Browser bundle

When you are done setting up tor, visit this address: http://foggeddrz4hjnxa3.onion

You can also track all the latest Bitcoin Fog news and warnings about hypothetical downtime or disturbances of the service operation on our twitter:

This website is just information about how to access the Bitcoin Fog in Tor network. Bitcoin fog is not hosted on the same server and can only be accessed through Tor. The clearnet website does not have any sensitive information, and hacking or seizing it will yield nothing except perhaps it's service termination. All the sensitive data is kept in the hidden bulletproof service, which will be operational no matter what happens to this website.

What is Bitcoin Fog?

The bitcoin network might be anonymous in terms of single-handedly revealing your ip address, but the transaction history is recorded in the blockchain and is publically available, which makes your anonymity very vulnerable. Once the interested parties, be it authorities or just interested researchers ( have acquired any one of your addresses or transactions, they could easily track your coins around the network. And knowing your transaction history, connecting your bitcoin addresses to real you is possible because you will at some point need to exchange your bitcoins to or from a fiat currency using a bank account number, a credit card, PayPal account or similar service which is much less anonymous than the bitcoin network. We are providing a solution for this: using our service you mix up your bitcoins in our pool with other users' bitcoins and get paid back to other addresses from our mixed pool, which, if properly done by you can eliminate any chance of finding your payments and making it impossible to prove any connection between a deposit and a withdraw inside our service.

How does the Bitcoin Fog mixer work?

You register an account on our website and deposit bitcoins to the designated address. After 3 network confirmations, your coins are registered on your Bitcoin Fog account, and you can schedule withdrawals. Each withdrawal will be split in a random number of payouts, depending on the amount, and the relative size of each payout will be randomized as well. Even the timing of those payouts will be randomly spread out over a period you will specify. Better deposit some bitcoins to the Bitcoin Fog, wait some time (for amounts above 75 btc we recommend a day, above 300 btc a couple of days, about a week for 1000 btc, etc.) and request a withdrawal, which will not have the same amount as the original deposit, leaving some funds in the Bitcoin Fog. Then you should deposit another batch of bitcoins and withdraw yet another amount, again different from the amount you have deposited. This time it can be lower than deposited, or higher, adding the funds you have left from the previous deposit. This way there is no practically reliable way to do statistical analysis on the blockchain and link your deposits to your withdrawals.

“Do I get the same bitcoins back?”

No. Transaction you will get back from us will be just some bitcoins transferred to your address, not “marked” in any way. A link could be made if you would get paid from the same address that you have deposited bitcoins to our service. This is not the case with Bitcoin Fog. The bitcoins you deposit stay on the random initial address we generate for you. Only when our main account is running low, do we transfer the money from your deposit address to the main pool. That way, you may get a payout from the pool, while your original bitcoins are still on the random initial account, not linked to your payout anywhere in the blockchain. Since it is just a bitcoin address like any other, there is no way to even see that you have deposited some coins to Bitcoin Fog, and not to a random account you have generated yourself (until the pool runs low and transfers your original money). Even if you waited long enough time for your coins to be transferred to the pool, there is still no reliable way to see that it was your original transfer that is the source of your payout, since it is mixed with other users' transfers. Another thing to consider is the amount of your withdrawal. If you transfer 1.262 to us, and the next day you withdraw ~1.26 bitcoins to another account, those amounts will be visible in the blockchain, and unless there were 10 other people that day that also withdrew just 1.26 bitcoins, the link between your deposit and your withdrawal will be pretty obvious. You will still have plausible deniability since nobody else has access to our servers and can actually prove that those bitcoins came from your account, but the link will be found nevertheless. This is why you should better never withdraw the same amount as you have deposited. We are already helping you to do this by transferring your money to you in multiple randomized payouts at randomized times (and optionally to different addresses), but to be sure you should withdraw to multiple addresses and different amounts than the one you have deposited. Also, make sure to change your deposit address every time and then to further anonymize your payments.

Why us?

There are a couple of similar services like: chipmixer, btcmixer and as we see it, the problem with most of them is that they are not professional enough, not secure enough, and not taken seriously, thus becoming subjects to easy hacking and other problems. We, on the other hand, are here for the long run. Our team consists of professional secure web application developers with more than 12 years of experience, and we have built this solution from scratch with security being our number one concern. We are the team, that launched the first bitcoin mixing service ever and we are proud of it! We strive to be a crypto mixer that just works and does not lose it's private bitcoin keys due to poorly configured backups or because of some hacker attacks on other sites from the same shared hosting, or because of any other silly reason. The service is running on a VPS which is manually configured for this very purpose, which does publically connected from the internet (not needed if using Tor). And, yes, our server is located outside EU and US, which makes it fully offshore and bulletproof. Bitcoin daemon is running on another machine, all suspicious activity is monitored and the website shuts down automatically if it even senses it is under attack. It is manually checked daily. For security purposes, the service operates through the Tor network only. You can be sure your data is processed securely and only by our server if you use our .onion address. On the other hand, this also makes us feel more secure, knowing that we will never be found and dealt with by proper authorities. (Even if Tor network would be compromised, we have taken all the necessary precautions to still stay hidden).

Are you going to run away with my bitcoins?

With a service like ours, it will always be an issue of trust of course, but we can ensure you that the service will continue to operate, simply because of all the time and effort, we put into building it, debugging it, setting it up at a secure location, etc., which makes it simply not worth for us to run away with a couple of hundred bitcoins which is collected at the initial phase. And once again, running through Tor makes it not likely for us to be shut down under pressure from the authorities. When in doubt about this, consider Silk Road. Of course, we are still going to have to earn your trust. We suggest you trying the service out with small amounts.

Do you keep logs?

Like all services, we keep logs, but only for 5 days for troubleshooting purposes. After that, they are automatically permanently deleted. ALL logs are taken care of. Even the bitcoin client we use is purged every week, starting with a fresh installation of only the blockchain, and importing all the addresses we need at that point automatically. That way, if you have received a payment from us a month ago, not even the address will be left on our server. If any service tells you that they don't keep any logs at all, they are most probably lying, because when clients come asking for funds they think are missing, not having any history is like turning our backs on them and not being able to provide any support.

Fees and requirements:

Our coinmixer takes a 1%-3% (randomized for obscurity) fee on each deposit. No other fees are in place, no complex calculations based on the number of withdraws or similar. The minimum withdrawal amount is 0.035 BTC. We do wait for 6 network confirmations on all deposits to prevent double-spending.
