“ Another coin scrambler Mixtum offers you a so-called free trial period what means that there are no service or transaction fee charged. The process of getting renewed coins is also quite unique, as the tumbler requires a request to be sent over Tor or Clearnet and renewed coins are acquired from stock exchanges. BTC mixer BTC mixer is another one that requires consideration. It supports Bitcoin cryptocurrency bearing no logs policy. It requires a minimum deposit of 0.001 BTC and the transaction fee is 4–5%. It supports multiple addresses of 2 or custom options and requires confirmation. No registration is required and it does not offer a referral program. Letter of guarantee is offered. Bitcoin mixer Grams itself is a brand on the Darknet so I believe not much needs to be said about it. Grams Helix is one of its subsidiaries and is one of the most reputed and widely used Bitcoin mixer services out there, it’s simple, modern, and definitely trustworthy. Grams supports only Bitcoins for now. It needs 2 confirmations before it cleans and sends you your coins. It obviously supports time-delay, but it’s automatically set to “2 hours” for some reasons. It also supports “Random transactions” for the deposit, the deposit address changes after each transaction and allows you to send more than 1 transactions to Grams Helix instead of sending in all your coins in a single go. The same is also supported for the “output addresses” (where you receive coins) and you can input as many as 5 different BTC addresses where your coins are sent after cleaning them. The coin-deposit address is valid for 8 hours, and any transaction not done within these 8 hours won’t be received by the platform." ”
