Mixtum mixer is difficult to base on (how you explained) but I want to use the platform with Tor.
If you don't actually understand the method that had been explained so far, I think you can always turn to the website because that is where you could see different format on how you can mix your coin in a way that suit your interest. Mixing is not something difficult like one could think but our safety is very important, that's why it is always advised to use a strong VPN that could hide our identity.
You can use the free trial to test run how the system works so that you can become more conversant with the system.
Sorry for the misconception. There was a typo in the message.
What I mean is that the MixTum is not difficult to use as the user explained. However, I visited the website as you advised and checked everything carefully. I want to use their mixing service for privacy priority, so I need to be careful and also sure that I am mixing the Bitcoin the right way.
You said "strong VPN" but for the record, some VPNs could provide their user IP address to the authorities, so I never trust VPN service.
The reason why Tor is used is to hide our privacy from the public. Other strong VPN can likewise be used too if they work well and keep us safe. Maybe you can take a look at the Mixtum website and use the free trial for a better understanding.
In your words using a strong VPN when privacy is prioritized is good? No, I will never trust platforms that can see, or save their user IP address and this is why I consider Tor to be the best solution for this.
