Since i joined bitcointalk forum i find it difficult to make a post relating to bitcoin, bitcoin is like physical money (fiat), and i want to know the difference between fiat and bitcoin, and without fiat existence can bitcoin have a name?, after thinking all this with seriousness i concluded that bitcoin and fiat works like brothers and sisters and no one can leave each other, so i want to know if any other digital currency can function without fiat?.
To this day bitcoin can not completely replace fiat. Many influencing factors such as technology and government regulations. There would inevitably be difficulties with the transition. But in the future with advances in technology, it is possible to happen. But I think it's better to have both. Fiat for short-term investment as exchange rate and buying and selling. While Bitcoin is for long-term investment.
