Bicoin Mixing Services


There are two main trusted tumblers and a third which was just released that I will post here along with some information about each. I will also post an extra free method that you can use on top of tumbling.

First - BitBlender. This service has been around for quite some time and is one of the trusted tumblers. BitBlender works with a shared coin system (one huge wallet sending many small payments) while the others seem more sophisticated (many wallets bigger than your deposit that will send amounts to the addresses you gave). In both cases it should work as far as blockchain analysis goes. (Thanks Wilderness.) BitBlender also has a high volume bonus program where if you send 10+ BTC within 7 days your fee goes down by 0.5%. They also have a referral program where once combined deposits from a user and his/her referred users reaches 10BTC in 7 days, the referring user will be credited 0.5% of all deposits.
Fee: Randomized 1-3%

Second - Helix by Grams. Grams started in April of 2014 as a simple search engine for products on the markets. After a few months they started Helix and have since created many useful services such as TorAds, InfoDesk, and GramsFlow. Helix has a regular version which requires a grams account, and a light version which does not. The full version of Helix has more fine-tuned controls like delays and sending the clean coins in more than one transaction. In the light version you send your coins to the address it gives you and as soon as it gets 2 confirmations it sends the cleaned coins (in one transaction) to your specified address. In the light version it can take up to 2 hours but most transactions are completed within 30 minutes.
Fee: 2.5%
Minimum withdrawal amount: 0.02 BTC
Maximum withdrawal amount: 21 BTC
Helix account cost (not needed for Helix Light): 0.01 BTC

Third - Pay Shield by SIGAINT. SIGAINT has been one of the trusted darknet email service providers for about a year now and has just announced their new tumbler on 16 June. I have not had a chance to try it yet but it claims to complete the tumble in 30 minutes. What's unique about Pay Shield is that it has a "Pay someone with mixed coins" feature. From their website: "[Pay someone with mixed coins] is primarily used to pay someone else with maximum privacy. Simply input the payees' Bitcoin address and the amount they expect and Pay Shield will generate a mix for you and calculate how much you need to send to make the mix work out to that amount."
Fee: Randomized ~1%

Now on to the free method. This is not recommended as a stand-alone method. There are many websites that store a large amount of bitcoins - stores, casinos, exchanges, etc. I personally use casino websites - send in your BTC, play a few rounds (penny slots or you'll regret it) and send it to your final destination. You can also send to your preferred website of choice first before sending it to your tumbler. With exchanges, it's best to find one where you can send your BTC and convert to LTC or another currency, then back to BTC.
