In 2014, Bitcoin's average price was $300-$400, sometime it even reached $700- $800
Let's say we consider the lower price $300, are you trying to say you sold the laptop at a flea market with (19,400 X 300) = $5,820,000 worth of BTC in it?

Nice catch and good logic !!
But how did you find it ? I mean how do we find out earlier versions of a post and where are the archives stored?
If possible could you please send me the link or any reference on how its done.
