I am just curious, and I can see that some other members are as well, what is your reasoning against posting the bitcoin address here? The string that begins with either "1", "3" or "bc1". Bitcoin addresses are public information. You can find all of them on any block explorer.
I'd assume that he wants to keep it private so in case he is cashing in those coins he is not doxxing himself.
The alternative would be that all of this is just a nice story.
