I'm in a bit of a bind and don't know what to do so I decided to bring this issue up here and ask for advice. Just like the heading reads, I received that amount of Bitcoin from an unknown address and don't know what to do about it. Should I spend it or let it be?
because not even Satoshi, Elon Musk or the president of the United States of America could give any random user such huge amount of fund unless you are a hacker and you hacked into an exchange to steal their funds. Because I think there is another side of the story you are not telling us here.
Well, I don't think there is any other side to this story other than the fact that op is lying possibly to make us believe he's an honest person, and also to again merit, and if he's reading and really wants to prove that he is telling the truth, like many already suggested to him, he has two options, and that is...
1. Take a screenshot of the 65 btc in his wallet and post here, and sign a message from the wallet address containing the 65 bitcoin.
2. Share the transaction ID of the 65 btc transaction here, and also sign a message from the wallet address holding the 65 btc funds.
If op doesn't do any of this, it's a clear indication and a confirmation that it was all a lie..
