Winklevoss brothers invested $11 million when 1 bitcoin is amounted to around $120. An now it soared to over $10,000, that investment could be something.
At that time no one exactly knows what will happen to bitcoin or how much it's price can be in the future. And I was amazed by their dedication to believe that they can benefit a lot from bitcoin, investing $11 million for bitcoin once thought cannot reach this far. They deserve billions for such patience. And I think they are already billionaire when they invest on bitcoin that day, so I guess now, they are more than just billionaire.
