Can you post your Bitcoin address?
Its within ops privacy right to either post his bitcoin address to support his or her claims, to me this is not needed and there are many other ways the newbie can prove to us that what he said is actually trues.
If you don't believe the OP just assume it's a made-up story. Because someone will not show the bitcoin address there are privacy reasons for me it is quite reasonable.
You can say that it is quite profitable to buy bitcoin at $22,000 if it is true and now it is around $52,000 many people buy in the lowest area before but make sure when you will withdraw the profit, if you wait longer after the halving then it will be better and it could be that the price of bitcoin soars.
