Its really a big gamble that this family has to make. They are betting that by year 2020, they will be millionaires. Just like all of us here, we want to be rich with bitcoin. But they have taken it to a different level. On must to think logically because its 2-3 years from now and how do his family survived then? I guess bitcoin has affected and changed a lot of people's mind but somehow, you should only invest what you can afford to lose. This family invested everything and chances are that they won't be living normally and have to wait till their gamble pays off.
