I was reading godlikeproductions in 2011 and there a man from UK posted a thread saying he is selling his house and buying £450,000 worth of bitcoins
After 6 months to 18 months, he posted there, he has earned some $20,000,000 from Bitcoins.

£450,000 to $20,000,000 means his money has multiplied about 40x. Was bitcoin price increase 40x in 6 months at 2011 ?
If it was not like that, then it just a fabricated story without some solid proof. If it was true, then maybe he has a crystal ball.
