I don't think there is a possibility about that happening. Bitcoin is meant to be convenient and decentralized. It is under the blockchain technology so it is better to stay as digital currency rather than become a physical one. Bitcoin indeed is the king of crypto and it can dominate even more as it stay as a digital currency. In future, we would see it more as a coin that will give great convenience to many and will contribute a lot in different countries economy. We just need to believe and stay faithful on it.
