$DOLLAR OR #BITCOIN

Fiat currency is literally use by almost everybody. All nations and kingdoms in the world use it for the exchange of goods and services, and it has been a tradition for communities for a long time making day to day living easy and enjoyable, both the literate and the illiterate make use of it alike. Digital currency (aka Cryptocurrency) pave it way out in 2008 by the invention of a man known as 'Nakamoto Satoshi' who invented #Bitcoin blockchain as the very first Cryptocurrency, since then hundreds and thousand of various coins and tokens on their unique Blockchains has emanated eg #Ethereum, #Steem, #Tron and many others which is actually playing a vital role in the world digitalization revolution. But the big concern here is why the competition? why would crypto fans want to do away with fiat currency and vice versa, In my opinion i think $dollar a major backbone of fiat currency is not better than #Bitcoin being a digital currency neither is #Bitcoin better than $dollar the physical money, they work hand in hand to produce better result in the world. So complimetary is better needed than competition. What do you think?
