I got good news tho, please read the section at the bottom of the original post.
How sure are you?
I am not convinced that any of the characteristics you have listed are enough to make a definitive link between these two accounts. It seems to me that there is a not insignificant chance that you have just stolen $500 worth of bitcoin from an innocent third party.
My thoughts exactly. Even though it sounds likely, is (for instance) 80% really enough for this?
There's much more than that going on in this case. Say for example, how high are the chances that someone will pay a 5% fee for a crypto <-> crypto exchange when they can use KuCoin to do that for a much lower fee?
I guess it depends on how often you do these trades. If you do it several times per day, it could be a coincidence. If you rarely do it, they're likely the same.
Even instant exchangers can do such a trade at 0.5 to 1% fee.
I am still verifying the transactions tho and I am going somewhere with it, like the scammers address being connected with the second persons address.
Try
https://blockpath.com/I've never done any trades like these before where someone hits me up for a crypto to crypto transaction, so having 2 in the same day within 2 minutes, both having the same sense of urgency is a first. One needs it within 5 mins and the other within 15 minutes "for a friend".
At this point, after going through both chats once again I am 100% sure these 2 accounts are owned by the same person.


Deon didn't even bother to ask for any vouches on my side, that has never happened. He tried doing what he did with the other account but it didn't work.
Also thank you for suggesting blockpath, hope it's going to help me.
