Can you post your Bitcoin address?
I can also say I bought Bitcoin when the price was $1 and hold it until now, I bought Bitcoin when the price was $3K during Covid-19 and sold at $69K etc.
Op does not have to post their BTC address if they don't want to, it is bad for privacy, especially when the address holds a large amount of coins in it. I understand you feel that the story is made up, and you may be correct, i have also called out a lot of members for posting fake and made up stories of how they bough x amount of BTC and made y profits, but they don't have to lose their privacy to prove their story, that is if there is a 1% chance that the story is true.
