I may be wrong, but I see about the same amounts being deposited and withdrawn before and after their departure, which was early August 2023, if I recall correctly.

This is their address: bc1qf8h5k6sash8007vpesymxkw2xsg5d0r3j4l5vmcrwpz2pqu66fjstzgd3r. Their last withdrawal before they stop processing payments happened in 9th of August 2023, in 96f687580d2ddec4328b9fca8aff8edda74c0f7de16b8be2da81413545308de3, correct? You're right that according to their last consolidations which happened in February 2024, as we can see, they are quite high in value, but how confident are we that these are customers' funds? If you check the history of that address, you can see that it was having more than just 7. The address was having more than 9 for some time, and people were withdrawing frequently, the address' balance was going up and down.

It would seem an exit scam, if there was a transaction in which they received 10 bitcoin, as an example, and then immediately stopped processing payments. But, this didn't happen. What's the evidence that their poor grew from 3 to 13?

So, you would have trusted a service which turned out to be "scam", but you would hesitate contacting a trustworthy campaign manager. Got it.
