Why are mixers necessary?

[LbtalkL]

Coin Mixers are really helpful in making transactions hard to track or untraceable at all but it is giving some scammers an advantage they are using it to anonymize their transaction and exit freely which is not good for the crypto community, even though it is very useful if you are concern about your privacy it is a good alternative for privacy coins.

In general mixers clone the initial transaction to ensure privacy, making tracing really difficult but not impossible.

Yes, we can say it was pseudo-anonymous and we can ensure privacy with it and it is certainly impossible to trace which hands it goes provided that you use those legit mixers ( a lot of fake mixers out there).

This is also a reason why some illegalities find it unnoticed and scammers will use Bitcoin mixers for they know that they aren't traceable and yeah, it works. Living to that purpose, it comes into the point that mixers also allowing such action because they never know where it is coming and never ask by then. That is how Bitcoin mixers it serves.

I don't think it's untraceable, as long as everything goes through the blockchain, everything can be trace, but with mixers, it will make it harder.
Mixers are most helpful for people who like to launder their money to get out clean going to their exchange but I believe more users are using it legally.

but it is giving some scammers an advantage they are using it to anonymize their transaction and exit freely which is not good for the crypto community, even though it is very useful if you are concern about your privacy it is a good alternative for privacy coins.

It's another advantage because mixers are also being abuse by criminals, so I don't know if mixers will last longer as crypto is more popular now and the eyes of the regulators are already looking unto us.

In very simple words, mixers are made for the purpose of hiding your BTC and sending you different BTC from different addresses to your desired address(es). If you send some coins to a mixer, it will keep them there for a while but immediately create you some tokens (not altcoins but kinda vouchers) which you can either give to the person you want them to redeem, or you can redeem them yourself on your desired address. These transactions will come from the reserves of the mixer so not to let anyone trace your old and new transactions. So, it is possible for you to anonymise your coins up to a level where they can't be traced at all.

I have been wondering what bitcoin mixers can offer me. With what I have read on this forum, bitcoin transaction is not anonymous, because it can be tracked using blockchain explorers. I do not know much about bitcoin mixers, can they make bitcoin transactions still anonymous? Or please, what is the function of bitcoin mixers?

Forgive me for my unpopular opinion, but mixers are to me only useful if you’re a newbie who scammed someone.

But it's not unpopular outside this forum. Your opinion is shared by different government agencies and financial institutions.

This is the second time I have seen you take a swipe at mixers. The first one was you calling it a tool for money laundering (https://bitcointalk.org/index.php?topic=5266574.msg54936148#msg54936148). Are you against anonymity and privacy? or only anonymity? If you are against both, what is your take on the ongoing developments that are said to improve or enhance on chain transaction privacy like taproot and schnorr? I'm just wondering.

Imagine scammer who just scammed someone and he needs a useful tool to obfuscate source of funds and thus make it impossible for police to identify who that sneaky criminal element really is. Your opinion is not unpopular despite your claim it is. In your statement you accept the fact that mixer are useful and suitable for scammers, because mixed coins can hardly be tied to our scammer. The goal of that criminal, as we have learned above, is to escape punishment by making a transaction anonymous and private. What if non-criminal also wants to preserve privacy, why can't he use mixer if he knows that it is a useful tool to achieve that goal? He knows that because even risky people who value privacy use it, why ordinary people can't? I don't understand, why criminal should have that right for privacy, but honest people should not in order to avoid being called criminal. That is unfair at least.
