They sold everything but they knew the risk and willfully entered into it. Whether its a good decision or the most foolish one, only the future can tell as to the time when they decide to cash out. If they invested at the point of $4000+ it they decide to cash out now, then they have made some amount of profit. But I am skeptical that by the time the price gets to $10000+ this family becomes automatically millionaires depending on the amount they put in at the time of their investment.
