So I don't have a grams account yet but I might just make one. Didn't see a reason to as of yet. Looks like its a coin tumbler. You bitcoin nerds should have a look and let the rest of us know:
Is it actually safe? Is it trackable? Whats the pricing like? Is it what we've been waiting for?
Or
Is it over rated?
Heres the description:
Helix is the definitive darknet bitcoin cleaner. Grams' helix doesn't just clean your bitcoins it gives you brand new ones which have never been to the darknet before. The helix system is more than a bitcoin tumbler, it is privacy and security wrapped in one.
And heres the link:

Edit: added link and description.
I read on the site (can't remember where) that there was a flat 3% fee.
