Why playing dice? Do you mean "gambling" your coins because of the risk of having your private keys stored by ChipMixer?

The best way to avoid this kind of issue would be sweep your new coins after mixing them. Something that in my opinion, almost everybody does. The smartest user wouldn't use this mixer and keep using the address generated by ChipMixer afterwards. That's why I think that many are exaggerating about this situation.

The risk of having your coins stolen by any other mixer is almost the same as with ChipMixer. How many Bitcoins in all private-keys generated by them do you think would be enought to make it worth an exit scam? Do you think someone mixing 10 or 50 Bitcoins would keep their coins in those addresses after mixing?

but the system might be a bit.... Complicated. Let's see how people manage to use it ^^

They CAN scam us and they MIGHT scam us! But it does NOT mean they WILL! Like others have said, it comes down to how much you trust them. ChipMixer offers features others don't offer and there are drawbacks for offering such features. If you don't like ChipMixer or is afraid they may scam you, don't use them! FYI, I have used ChipMixer recently! Both their service and their support are great!

I was not familiar with the letter of guarantee method used by Bitmixer, but now that you have mentioned it, I wonder why it isn't possible with ChipMixer. Once the mixing amounts have been confirmed by the user, would it not be possible to sign a message containing the final chips being output in the mixing process, along with the input? The chip sizes may not be known prior by ChipMixer, but once they are chosen by the user wouldn't it be possible to include in a signed message?

I have not yet tried either of the mixers out myself, so please forgive me if I misunderstand the process involved in either of these.

--- MESSAGE ---
This is a receipt / confirmation that you have received following
private keys from ChipMixer:
### CHIP SIZE:  BTC
Address: 
; Private key: 
### CHIP SIZE:  BTC
Address: 
; Private key: 


This message is signed with ChipMixer's Bitcoin address:

That is not true. Bitmixer offers letter of guarantee. They show input and output addresses and signs them with their private key. Customer see it before they deposit. This is very nice feature and we would really like to have it, but we cannot. Their method is non-interactive and both inputs and outputs are known before deposit and if anything goes wrong, they can complain public. Output of ChipMixer is unpredictable - you can pick whatever chip sizes you want, you can bet, you can freeze them with vouchers. It offers better privacy, but downside is that we cannot offer letter of guarantee.

Hi ChipMixer, can you share with us why using a chip mixer is better than using an online exchange lik Coinbase, Xapo, and others?

Does @chipmixer have any sort of strategy to prevent this from happening? Maybe get the person using the chipmixer service to insert a bitcoin address in the beginning and then just before the private keys are revealed, they have to sign a message with the exact same address to prove that it is still them accessing the private keys and nothing fishy is going on?

There is nothing any site can do against this. You can say any exchange, casino or other site gave you a deposit-address and changed it right after you deposited.

... Which is why ChipMixer will not refund.

So i'm wondering as well - what if someone decides to frame Chipmixer by saying that they got hacked/chipmixer did an inside job when they really just sent the bitcoins to themselves? there would be no proof either way, but the guy can do this under multiple accounts and then people will say chipmixer is a scam.

Good question. Funds from cannot be stolen, unless you know private key. ChipMixer knows the key, you as a customer knows it and nobody else. Let's assume there was a hacker who somehow got the private key too.

How he got it?

Method 1. Eavesdropping

Customer visited http website? No, it redirects to https and you cannot start mixing with http.
Customer visited https and it was eavesdropped? No, https is encrypted, so private key will also be encrypted.
Customer visited .onion website? It is encrypted, so private key is also encrypted.
Customer visited MITM or forged copycat of ChipMixer? Attacker serves his address and does not give you any chips. Why risk that you will sweep them immediately?

Method 2. Hacking the server

Destroying the session deletes chip private key. In this case attacker would sweep hot wallet and active sessions. If for some reason you do not want to sweep everything instantly, there is no reason to sweep single private key of active session. This would only hurt ChipMixer reputation and that decreases your change for large loot.

This shows that single private key cannot be evesdropped, and hacking the server would result with much bigger mess.

Another group - ChipMixer. Stealing single chip hurts reputation. It is not worth to be little dishonest, when you pay much more for ads and sig campaigns.

Last group - Customer. Let's say you sweeped 1.024 BTC chip. You can write a post that somebody else sweeped it and you demand a refund. If you don't get a refund, you've lost nothing. If you get a refund, you've earned 1.024 BTC and nothing stops you from posting more complaints. Which is why ChipMixer will not refund.

There is a difference between ChipMixer and other mixing services, online wallets and exchanges, i.e. ChipMixer gives you private key. When we withdraw Bitcoin, you will get a receipt or a signed message saying you have withdrawn xx.xxxxBTC to 1xxxx...(or 3xxxx...). You or the service can check the withdrawal address you have given to see if you have gotten your bitcoins or not. Even if an accusation is made, you/service will be able to provide sufficient proof. If you couldn't, say they blocked your account, that will only make service's reputation worse. But that's not the case with ChipMixer. They are giving you private key which makes it harder to prove who send Bitcoin from that address.


Yes, you are right! However, anybody, especially competitors, could use this flaw to destroy their reputation.

If someone accused ChipMixer once, maybe a lie!
If it happens second time, is it really as trusted as others say?
If it happens for third time, suspicious!!!
If an accusation is made again, negative feedback!

As with other mixers and as is the nature of Bitcoin, there's not much that can be proven when you accuse someone of stealing.

For example, if a mixer/wallet/exchange is accused of stealing, no one can prove who actually spent the bitcoin since the only proof would be held by the person stealing and by the original owner, who might be the same person if the accusation is false. How could people know who is being truthful if the result would be the same regardless of whether the original owner spent the bitcoin or if the other party used the private key? It could even just be a hacker who managed to get the private key through other means.

So in the end it all just comes down to trust and reputation of ChipMixer.
