Name: Grams Helix
Helix is a bitcoin tumbling service created and operated by the creator of Grams.
What tumbling your “Bitcoin” does is let you mix your bitcoin with those of other users, thus making them “clean.”
While this is not a full-proof anonymity protection method, it can help discourage less persistent trackers in figuring out who you are.
This is mostly used by darknet market users to sever any ties to bitcoins they use in purchases over darknet.
The process is fairly simple and it requires few minutes up to few hours to complete, after which you are left with bitcoin which the owners of Helix are claiming cannot be traced back to you.
As stated above, the primary benefit of Helix and any other legitimate bitcoin tumbling service in general is that it helps increase the level of anonymity protection.
What separates Helix from other services, according to its creators, is the fact that the tumbled coins aren’t just mixed together, but rather also traded in for new, clean ones before mixing.
This means that you will likely end up with bitcoin that has never been on darknet at all and is completely clean.
Another thing that is important to note is that Grams has a bitcoin reserve being created in case that bitcoins from Helix gets stolen.
While they say it is more than unlikely that such an event will occur, a fund is created to return any stolen bitcoins should the need to do so arise.
Like with any other bitcoin tumbling service the security question arose very quickly.
It is not a secret that there are people working on de-anonymizing the bitcoin blockchain and that any other bitcoin tumbling service is prone to constant hacker attack.
Many argue if the need for tumbling your coin even exists, given that you will probably be found out through ordinary police work way before anybody even looks into the blockchain.
Another downside is that as many other tumbling services you will need to pay a 3% fee for using it.
This may not sound like much, but if one considers tumbling 50+ bitcoins that amounts to $400-$500 just to perform an action that many believe is redundant in the first place.
Given the fact that Helix is not standalone software, but rather an online service, it cannot be downloaded, but rather it can be used form this link: https://grams7enufi7jmdl.onion/helix or https://gramsflow.com/helix
The process of tumbling your bitcoin is actually a rather simple and quick one. You will need a clearnet wallet using which you will buy the bitcoins.
After that you will need two more wallets on darknet, one to send your bitcoins to and use as input wallet and one as an output wallet on which you will receive your tumbled bitcoins.
It is important that the two darknet wallets cannot be linked to each other in any way, which means you have to create completely different passwords and make sure that those do not have any information that may link them to you.
After you receive your bitcoins it is advisable that you perform a “taint check.”
Visit https://blockchainbdgpzk.onion/taint/yourbitcoinaddress (replace “yourbitcoinaddress” with an actual bitcoin address from your output wallet) and search the list for the address of your input wallet. If you are unable to find it, it means you have successfully completed a tumble.
