If you are not satisfied with our service, please contact support in 48h (while your session is not yet deleted) and we can help you. Waiting few days then writing on forum while advertising bitmixer looks bit weird.
I have a question that probably a lot of users just starting to use chipmixer will probably share. What if the session is automatically destroyed after 48h and something happens, say the funds get stolen/private key doesn't work? Will support be able to help the user then?
I thought about this while doing the alpha-testing. Let me go over both options:
"say the funds get stolen"
If this happens, there are several possibilities: It could be ChipMixer keeps copies of private keys and took your funds, but that would destroy their reputation instantly. It could be you're lying, hoping to get extra money, or just with the sole purpose of destroying ChipMixer's reputation in favour of competitors. It could be (and I think this is most likely) your own computer got compromised and someone stole your funds. If this happens, ChipMixer will get the blame anyway, while there is no way to prove who got compromised. I think this is a risk for ChipMixer's business model.
If you don't want to trust ChipMixer long-term with the private key they provided, a very simple solution is to just transfer the funds to an address you created by yourself.
"say private key doesn't work"
You can test this by importing the private key into any wallet to get the address associated with it. You can do this on an offline computer, or even from an Ubuntu Live CD using bitaddress.org's wallet software from a USB-stick. Then, you can check the balance of the address in any block explorer online.
