Why does this user immediately go and pay 10.6 ETH to the forum after he lost his coins in the mixer?
Not immediately, but after other users expressed doubts about the accuracy of his claims. I guess he just wanted to prove that they had a large number of cryptocurrencies. It certainly helped draw attention to himself and his "case".
Am I missing something here?
Nobody in their right mind would through even more money down the drain after they lose a significant sum, except I guess fools who are the type that fall for scammers, but it's already been established that a fool and his money are easily parted, and that is not what's happening here.
Here is something that was recognized as illogical in his scam accusation:
This is part of a chat he had with Unijoin support, where he declares that he is not looking for a return of 15+ Bitcoins.
You, 3 days ago
No. Always had the correct web address. I repeat that I did not leave your web address, and there were several successful mixes before. Also, there are no infections or access to my machine, otherwise the rest of my funds would be lost. Im not asking you to return the money, but would you like to at least try to understand what happened. In fact, the user created an order on your mixer, the mixers web address was correct, not phishing, your system generated a letter of guarantee, then the money did not arrive to the user, and the user saw that the letter generated by your mixer contained a different key.
Later he gave an explanation why he said he was giving up the refund
I wrote that I did not demand a refund only after they refused to do anything. I thought it would motivate them to do something to solve the problem. Obviously this was actually a failed attempt. Also this phrase caused a wave of skepticism on the forum so I showed the seriousness of the situation by making a donation to the official forum wallet.
Previously, on two occasions, he reported different amounts for which he was scammed. Where the difference is only 5 BTC
He explained this as
I edited the mix amount because it's quite large and I think it's easy to track. It's not even 10 or 15 btc.
Now think that after all he donated 10.6 Ethereum to the forum.
Of course, it does not help that Unijoin does not have its official representative (communication goes through the manager), so we are deprived of more details from that side and answers to some other questions.
