Helix doesn't just clean your bitcoins it gives you brand new ones. Helix system is more than a bitcoin tumbler, it is privacy and security wrapped in one.
The Helix process uses a new proprietary technology which has never been used before with bitcoin tumbling. The coins are not just mixed but traded out for new ones before mixing. By trading dirty coins for out for new coins helix severs the taint trail.
Helix is easy to use since it is integrated in to your normal Grams' account. Load bitcoins in to your account as you normally do. You will find a Helix withdraw form on your account bitcoin page. Once you put in the amount you wish to withdraw and the address to send to the system with start the process and use the coins already in your Grams' account.
Helix has it's own servers not connected to Grams. The several bitcoin clients it uses are on a completely separate server from Helix and Grams. Even if Grams was under attack or compromised it would not effect the Helix system.The bitcoin clients are also switched out regularly to protect against a server compromise.
Privacy is a main concern for bitcoin mixing which we take very seriously. All logs are deleted after 7 days, but can be deleted by the user as soon as the helix withdraw is complete . Once all transactions have been sent for a regular helix withdraw the user will receive an encrypted message on grams with the transactions hashes. The message will auto-delete after it has been read. Helix light and market users get a status page for each helix. Once the helix light/market is done the user can delete all records of the transactions with a single click.
The Helix system has a flat 2.5% fee. It is on the high end of the fee spectrum for bitcoin tumblers for a good reason. This system has lots of fees involved with many transactions to and from the exchanges. For the cleanest bitcoins on the dark web we must top-up end prices to ensure quality.
Grams has been using this system for a while on the back-end. Every bitcoin loaded in a Grams account starts the process as soon as it arrives. Helix has a reserve of clean bitcoins which are ready on demand for smaller orders. The helix process has a maximum process time of 4 hours. So even without the reserves you will start receiving your bitcoins in a timely manner.
