How do you know?
I think back in the days when OP made that statement he seemed to know what he is talking about.
At least he understood how much power this invention, Bitcoin, will have.
When OP made this thread (5th of June 2011) the price of BTC was $18, right in the middle of the first bubble Bitcoin has seen.
Round about 5 years later we were at $630 to $650 and dropped due to the Bitfinex hack.
That's an increase of more than 3000%!!
And because of the fact that OP never has given any timeframe I would say wait another 10 years, which includes 2 more halvings, and he may have proven you being right.
