Bitcoin can be good as a fiat currency we have right now. It can buy good and services. It serves as a digital currency in this digital generation. It can be good because bitcoin can be exchange for alt coin which you can buy services and good or you  can exchange alt coins for bitcoin. The only difference of it to the fiat currency we have right now is that it is decentralized, the community itself is the one who facilitates and promote and I think bitcoin is good for buying goods and service but for me I prefer that tangible money over bitcoin for now because bitcoin is still on it development stage.
