I managed to mix my coins and used the "Sweep to another address" function. The addresses on my independent wallet I chose to send to are listed alongside a "pending" state and a private key. I understand that there can be a delay of up to twenty-four hours but it has been around seventeen thus far and with it being the first time I have used Chipmixer I am starting to worry that something may not have went as it should. There are Private Keys listed but I do not know whether I need them for this particular transaction or not.
I appreciate these may be rather rudimentary questions but I haven't used this kind of mixer before and would be very thankful for some guidance or advice on whether this is normal or what I should do next. Thanks.
