Because I just got it recently am not asking to sell it to anyone on this platform all I need to know is where and how can I sell it I can give proof if needed
Cmon, do you really think that that people will belive you that you somehow got 10,000 BTC , while just a few weeks earlier you were trying to get 0.3 BTC loan?
You are a bit late with your bs story, something like that could maybe work if we were in 2009/2010 but not now with these prices.
Regarding the proof, you can always sign the message and prove that you really have that amount, but we all know that you won't do that and will probably just disappear or more likely make a new account and again attempt some type of scam.
