To sum up, the BestMixer code is necessary to protect a client from getting his old coins back under any circumstances

How secure is storing this code for the client's privacy?
I'm mainly thinking about the following (unanswered) questions that were raised about BitMixer.io.
Just 3 weeks after the first post about it, BitMixer closed. The questions were never answered, and I'm still curious. Prepare for a long quote (please note that I'm not pointing fingers, but I'd like to hear your opinion on this):

It is good solution for stay anonymous in digital coins, the other way is use other bitcoins mixing services https://cryptomixer.io/
It is still working secure, fast, reliable and huge volume of mixing bitcoins, You get a discount on service fee when you use CryptoMixer regularly. More you mix less you pay.

This means that CryptoMixer keeps logs and may link multiple transactions to a person, right? How is that a good practice for a mixer?

Or how else would they know that you are a loyal costumer and already mixed more than 50 BTC?

Nice fuckin catch, bud! The last time I brought up a similar concern, a few days later the entity - ... BitMixer ... - closed up shop.

See if the following is similar:

What is a Bitmixer code?

After your first exchange you will receive a special Bitmixer code. This code makes sure that you will never receive any of the previous coins you have added to our reserves in any subsequent transactions you make with Bitmixer. In other words this ensures that you remain untraceable.

Day 1: I mixed U$100 worth of bitcoins and received a Bitmixer code so that when I mix subsequent coins I won't received what I previously mixed back. Fine!

48 Hours Later: I mixed another U$100 worth of bitcoins and received bitcoins back which none were of what I've mixed two days prior. Fine!

36 Hours Later: I mixed another U$100 worth of bitcoins and received bitcoins back which none were of what I've mixed two transactions prior. Fine!

Question: How were the last two transactions achieved given the following? ...

Our servers are located in a country where US authorities cant get access to the server without a local court order. Bitcoin is not considered as money here, so we cant be a money-laundering service. We use encrypted disks. We delete all order data after 24 hours. We completely erase old bitcoin addresses from our wallet after coins are sent out. Even if the server is seized, they will find nothing.

Clearly, my Bitmixer code remains on file attached to bitcoin wallet addresses I've previously used, else there would be a strong possibility of me receiving some of the coins back that I may not want attached to me, but that would be an impossibility given that ALL order data is purged from your system within 24 hours, as stated above, resulting in the 3-LAs et al. finding nothing.

Further, I'll be paying you a fee to mix coins stemming from a nefarious act with the strong possibility that I'll be receiving coins stemming from a nefarious act tens of times worst than what I'm tryin' to hide. Surely, wouldn't that bring the feds to my door a knockin' a helluva lot quicker? It'll be pretty embarrassing for me to defend myself if accused of running a underage goat brothel when in fact I ONLY pimp out adult chickens and occasionally a matured goose (soon to pimp ducks - drakes and hens).

Humor aside, I look forward to your reply, devs.

Now we have (paraphrased) ...

"There are no transactions keep on our servers. Plus, you receive a bonus - the more you mix, the less you pay. Yes, we keep records so that nobody games the system."

"I'm the manager over all the crypto mixing entities.
What's your position? Darknet crypto-based companies?"
