Lightning network for BTC laundering

[mitsos2017]

I don't know exactly how lightning network works, but is it possible to use it for Bitcoin mixing?
In other words, are the transactions in this network traceable?

You can reach info about what is lighting network really easily. I made a search for you and get this info very quick.

The Lightning Network is a "Layer 2" payment protocol that operates on top of a blockchain-based cryptocurrency (like Bitcoin). It enables fast transactions between participating nodes and has been touted as a solution to the Bitcoin scalability problem. ... Lightning Network implementation also simplifies atomic swaps.

why would you want to bother with something complicated and not-anonymous to launder your dirty money when there are lots of easier ways to do it with a better efficiency? just take a look at how others are doing it, like all these ICOs that have been laundering their millions in broad daylight while calling it "fundraising"

Or split their coins to smaller amounts sent to multiple wallets, and have them deposited, and "played" in dice-game sites, then withdraw.

Others have raised fair points here, but i'd like to take a step back and re-visit OP's original question: can the LN be used for mixing...

Short answer: not really...

Long (simplified) answer: The lightning network is a network of nodes that have open channels between them. Both opening and closing transactions are on-chain. After a channel has been opened, what basically happens is both sides of a channel exchange signed transactions that are not broadcasted to the bitcoin network... When a channel is closed, the transaction is broadcasted.

So, basically, you have an usnpent output you want to mix... What will happen?

You use your "dirty" unspent output to fund your lightning wallet (or maybe the unspent output is already funding one of your mightning wallet's addresses). This is a 1-1 transaction and is traceable.
You use the traceable unspent output to open a channel with somebody else... This is on-chain and traceable
It doesn't matter how much update transactions get sent between you and the other side of the channel, once it closes it's once again an on-chain transaction funding either one side's address, or (more likely) partially funding an address of both channels...

The thing is: if you send funds using the LN to one person, and this person sends funds back, it'll most likely go over the same channel, and it'll cancell eachother out...

It is possible to add more addresses to the channel? For example, if a user sends a transaction via an opened channel to the mixer and then getting a transaction on another address via the same channel?
In this case it seems like mixing information will be stored only on mixer. Or not?
