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.

That's what you get for playing against the odds and also having belief in what you are doing. If you have belief in what you are doing then there isn't anything in the would that can stop you from succeeding but if you doubt then you will be in great trouble.
