It is a good investment as it will no only increase in value over time, it also gave birth to the other beautiful technologies that have come up after it. Bitcoin will always be the father.
It is good investment right now, because as we can see, the price is going down since this China banned crowd funding, this was like a whale causing the panic sellers sell their bitcoin and the result is the continous bitcoin's price dump. Lucky for those people who do have money to buy bitcoin, the next PUMP they could make a really great profit.
