I think they missed the point. You can't just look at the address, you have to analyze the wallet.dat to see if it's the same one. There are many different wallets in circulation from the same addresses but different wallet.dat. I could now send you two different wallet.dat files from the same 4000BTC wallet address. One of them is a fake and the other one is unsure. Therefore, you must always check the files beforehand and then claim whether you really have the same ones with you.

The 10 wallet.dat files of mine might not be the same ones they have and that is the point I am trying to make.

Since I am only allowed to write 2 private messages per day (is limited as a newbie), I can never reply to your message immediately. If you are interested in an exchange, please send me the one wallet.dat and I will send you my wallet.dat files, which I currently believe are not fake.

Many greetings
