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.

Many stories like this, when bitcoin prices are not more than $ 100 many big investors who dare to take risks so that they sell anything to buy bitcoin, now they are a new rich people. I think the opportunity to get big profits is still open because someday the price of bitcoin can reach hundreds of times than now.
