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.

This man has the hell huge courage in his. He can sacrifices the thing he has and in return he gets more than what he gave. This is the prove that bitcoin is worth risking for. If you take the risk then probably you will get something in return. Return that is greater than what you have expected. Bitcoin is very powerful so as the people who have the courage.
