Thank you for your answer.
I need a pro with authority because I need my evidence to have authority.
Yes If i remember correctly:
1. 175 btc from wallet A to exchange
2. some other small and big transactions followed from wallet A to various.
3. the complete contents from wallet A where then send to wallet B.
4. wallet A unfortunately was deleted and as a result I need to show evidence that the transaction of 175 btc to exchange is likely done by me and not by the other party(scammer)
So my request again: please give me a list of companies who can give me the evidence I am looking for. als I need to add that myself I am somewhat not really experienced in blockchain analysis and this is another reason that I need someone who knows what he doing.
I thank the community a lot for the answers.
