The Helix process (only on HelixGramsLight.com) 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. The new coins have a 0-history policy meaning there is absolutely no trace back to you. By trading dirty coins out for new, freshly mined ones helix protects you from blockchain analysis - better than any other service that sends you old, often dirty coins.
After the intial transaction you send to Helix has 3 confirmations, the coins will be cleaned and sent back to you with 1 transaction immediately from our 1000s of mining stacks. The process can take up to 6 hours, but because of reserve clean coins, 95% of all helixes are sent with in 30 minutes.
The Helix system has a flat fee. It is on the low end of the fee spectrum for bitcoin tumblers for a good reason and is randomized. This system is extremely advanced with the highest privacy features and gives the benefits back to the user by using extremely sophisticated bitcoin exchange technology.
