Coin mixing has always been useful for those trying to protect their private Bitcoin and crypto activity. However, recent regulatory action calls its legality into question.
That depends on whether they are custodial or non-custodial. Using either type of mixer does come with some risk. The recent arrest in the U.S. of Larry Harmon from Ohio has cast the issue of coin mixing back into the spotlight.
What is Coin Mixing?
Coin mixing is a privacy-enhancing technology for cryptocurrency users. Privacy coins aside, most cryptocurrencies, including Bitcoin, are pseudonymous and easily traceable on the blockchain in their transactions. Crypto-sleuthing firm Chainalysis has turned crypto transaction tracking into a very profitable business by selling its services to law enforcement agencies.
Coin mixers or tumblers allow users to split their funds into small parts and rewire them through thousands of microtransactions, sometimes into and out of a comingled pool, to a new address, thereby making it difficult for anyone to follow the cryptocurrency.
Mixing is a service that tends to appeal to two kinds of people: criminals seeking to hide ill-gotten gains or avoid taxes and people who want to protect their right to privacy. Depending on how the mixers work has a significant bearing on their legal standing.
Custodial Vs. Non-Custodial Mixing Services

Helix offered an Internet-based service that… enabled customers, for a fee, to send bitcoins to designated recipients in a manner which was designed to conceal and obfuscate the source or owner of the bitcoins. This type of service is commonly referred to as a bitcoin ‘mixer’ or ‘tumbler.’” Read More...
