Both fiat and bitcoin oscillate in value, the main difference is that fiat has a much larger volume so the oscillations are not as
noticeable as it is with bitcoin and other crypto currencies.
For me bitcoin is far more valuable than any fiat, and the main reason for that is that it has a limited supply and is independent of all countries
and man made laws, whereas fiat isn't and they print it more and more, even as we speak now..

Bitcoin is worth for the most people I think. Why it should be not worth. You can do many things with it and it has a value and that is very important. I hope that more people will know that Bitcoin is very good to use and that you can earn some money with it.
