Wasabi's Chaumian Coinjoin Best Practices

[zeycus]

I've been using Wasabi's Coinjoin for a while in an attempt to tumble by BTC. It is not much, I am getting the grips of it. The feature looks nice, but I have a few doubts on the best way to do it. For instance, after some hours when I reach home and there are several UTXOs "ready" (with a high anonymity set), is it a bad idea to move them in same time to my real wallet? I have to move them because I am using Wasabi only for the coinjoin, won't leave the crypto there. Of course I mean moving each one to a different address, but very close in time. Would this help trace the coins to me?

Another doubt: say I have 1 BTC to coinjoin. If I send it in one piece and order a coinjoin, I'll get two parts, one gets anonymity, it is 0.1 or 0.2 or 0.4 BTC, the other is the rest, not anonymized. Then I have to order coinjoin for the change as well, it is kind of slow. I thought I could send directly to Wasabi 10 different 0.1 BTC transactions, and coinjoin them separately, is there any problem with this? And if I do, and soon all of them are ready, is it a bad practice to move them to my real wallet in a short range of time?

Thanks!

I do not know if you will read my post, but ask this guy @nopara73

and you can also ask in this thread:

Wasabi Wallet 1.0 Is Released

[nopara73]

Let me try answering this question. It's best to use Wasabi alone. Meaning, this is bad:

1. Send coins to Wasabi.
2. Mix.
3. Send coins to hardware wallet.

The reason this is bad is, because every wallet, except full nodes, fullspv nodes and client-side-filtering nodes fall for network analysis or network spies (like your wallet companies backend.)  

After that:

1. Don't combine red shield coin with green shield coin. - If their histories cross each other the green shield coin is deanonymized.
2. Try closing the loop as fast as possible. - Use the "Max" button to spend whenever you can. The dead change may problematic later.
3. Try avoiding coin merge if you can. - Merging 2-3 coins is fine, there're definitely people coming to mixes with more than that. Maybe up to 10 doesn't ruin much of your privacy, but over 10 be careful.

And finally to address your specific question:
> is it a bad practice to move them to my real wallet in a short range of time?

It's a bad practice for the above mentioned reasons, but not a terrible one depending on your threat model. In fact you can completely eliminate privacy issues if your "real wallet" is a full node and you are using its coin control features to spend.

Thanks!

I see your point, still I would not feel too comfortable with my crypto on a computer online. In fact when I started using Wasabi I realized I miss the coin-control feature you describe, I need to take a look at it.
