Is it possible allowed to send multiple transactions to deposit address generated by chipmixer?

Yes.

Or should it be one transaction?

Thank you

Yes, i'm aware that this decreases privacy. I'd be great if you could generate multiple deposit addresses during same chipmixer session.

I also ran blockchain study on spending  chipmixer transactions and there are two interesting things i noticed:
- Most people, like 95%+ are combining the chips while withdrawing them. They do not withdraw/spend each chip to separate addresses.
- The 0.512 and bigger chips have very few spending transactions. The difference is very significant significant. 90% of spending transactions involve smaller chips

Data from 5-6 days of blockchain transactions.
Number of spending transactions involving given chip size

0.032 337
0.016 676
0.064 200
0.256 67
0.128 94
0.512 39
1.024 22
2.048 21

Based on these numbers, does using bigger chips due to fewer transactions seen on blockchain, have any negative impact on privacy?

Making several deposits to different addresses in a short amount of time still reduces privacy. That's why ChipMixer uses vouchers: you can keep them for a long time to make it much more difficult to link your individual inputs.

Can you share your findings?

- Most people, like 95%+ are combining the chips while withdrawing them. They do not withdraw/spend each chip to separate addresses.

That makes sense, to a certain extent. If you have to pay something that can't be paid from one chip, you add another one. So if you have 12 chips and need 3, you only use 3 and leave the remaining 9 untouched.

Based on these numbers, does using bigger chips due to fewer transactions seen on blockchain, have any negative impact on privacy?

It's hard to say: If you deposit exactly 0.512 BTC, get one chip, and spend it the next day, it's possible to link a list of possible inputs to possible outputs. But you could just have well deposited a much larger amount, or several smaller amounts (through the use of vouchers). You can also have months or even years between creating and redeeming the voucher. An observer can guess and make assumptions, but without additional information they can't know for sure which input belongs to which output.

I would argue that using a bigger chip has a positive impact on privacy, in some situations.

If you spend two chips of equal value, someone looking would know that you sent the chip value to CM on or before each chip was created. With a single, larger chip, someone looking would know you sent the chip value on or before the date the larger chip was created.

If someone knows all transactions going to CM, the list of transactions that meet the criteria of using two small chips is going to be smaller than using a single, larger chip.

The caveat is using a single chip that is larger than necessary. If you use a very large chip that results in a large change amount, it may benefit your privacy to rather use several smaller chips, depending on the circumstances.

Clearly there will always be more smaller transactions of a certain size than bigger transactions.
But you can easily deposit a big value and withdraw a number of smaller chips.
And you can easily deposit a non-standard value so it's not seen as a deposit to CM, but of course, this means that you also make a donation.

Clearnet site working?

[LoyceV]

Clearnet site working?

It's offline from my end. But the Onion site works fine, and is better for privacy anyway.
See Tor Project to download the Tor browser.

It's down for me also and I tried with different browsers.
I know we can always use onion website that I usually recommend, but it would be good to hear from official Chipmixer account with explanation what happened in this case.
Probably some ddos attack or scheduled maintenance.

It got weirder, it looks like the site currently uses the wrong certificate:

The certificate is only valid for *.interactio.live.

it would be good to hear from official Chipmixer account

Agreed.

[dkbit98]

Confirmed here.
This is using LetsEncrypt certificate anyone can get for free, and that interactio.live domain was registered this year by amazon
I don't remember what kind of certificate was used originally by Chipmixer, but this stinks more and more like some kind of attack, better to avoid using clearnet when it goes online.

We had maintenance problem with clearnet website. It's resolved.
Tor hidden service website was not affected.

I used your service and my transaction has over 12+ confirmations, but i never received my chips or anything. In the Deposit step it shows no funds either.
It also shows no confirmed transaction on step 1.

I sent an email but it has been over 24 hours and I have not heard anything back from you,
will this be solved or are you guys scamming?

From what I remember from doing some tests, have you tried skipping straight to step 2 to see if your chips are there?(don't press ahead to step 3 yet though)

If that doesn't work, you're probably better off waiting for them to respond by email (make sure you have your session token noted down too). Support can take around 3 days to respond sometimes but they're fast at resolving problems once they're aware of them.

[TeddyXc]

Yeah I tried going to step 2, but that shows that i have no funds, so i cant do anything.

I have everything noted down and I sent them the information they ask for when you run into issues on the site through email.

Are you sure you used official Chipmixer website or their v3 tor onion version?
I have seen people getting scammed before by using phishing websites especially using clearnet website, or by searching chipmixer website in google.

[TeddyXc]

Yeah I did. Chipmixer.xyz and chipmixer.com

[LeGaulois]

Yeah I did. Chipmixer.xyz and chipmixer.com

.xyz has never been a TLD used by ChipMixer.com.They use .com and only .com (on the clearnet).
So if you used that .xyz, you got scammed

[NeuroticFish]

I have everything noted down and I sent them the information they ask for when you run into issues on the site through email.

If you have everything noted down please check if:
1. The ChipMixer website you've visited is one of those posted in the first post of this topic.
2. Maybe you can restore your session and see if the bitcoin address you've sent to is 100% identical with the deposit address posted on the website

[LoyceV]

Yeah I did. Chipmixer.PHISHING.xyz and chipmixer.com

How did you get to the .xyz site? Google? It's the first site Google shows me when searching for "chipmixer".
I'm more and more disappointed in Google nowadays: they used to take pride in providing the very best search results, but when searching for chipmixer they usually show a phishing site first. My browser even remembers I reported them to Google a long time ago. Google doesn't care.
And every time someone falls for it, the scammers have more funding to continue their scam

I've stumbled upon something weird here, on the bottom of the page there are 4 linked DMCA

One of them:

makes total sense as far as I understand it

But this one:
