Years ago, few people believe on bitcoin and look at them now, they are now millionaire simply because of bitcoin. I believe that bitcoin will continue to make millionaires, and it will happen in next 5years. This is the best time to accumulate more bitcoin for us to become rich in the future through bitcoin.
yes they are really the luckiest people who invested money in bitcoin in very beginning. i think most of the people got the opportunities. i think still there are a lot of people who are holding their bitcoin although they are now getting double their profit but still they are sure about bitcoin and its price to increase.
