I on personal basis also believe that each person who can foresight bright future of bitcoin has invested affordable amount in it. In future the prices will surge high and it will be widely accepted as mode of digital payments with faster speed and low fees. But selling your house and all other assests for this volatile currency can never be idea or advice of smart person. Invest up-to only that much which you can afford to loose. But you will surely gain profits in long run if you hodl with patience.
