i wonder: if Bitcoin will become the main coin, what will happen to the money we are using now like us dollar?
As far as cryptocurrency is concerned, there is no doubt that Bitcoin is the first and the most known coin of all times...it is currently the King of all Cryptos and all the rest are just considered to be altcoins (even including Ethereum and BCH). Now, maybe you have in mind is the fiat or paper money we are now using...what will happen to the US Dollar if all the people of the whole world would suddenly be using Bitcoin?
Well, to answer that question I am giving you another question: Would that really be possible to happen? And my answer is a big NO. I know that Bitcoin may have a good future as a digital currency but it will never totally replaced the fiat money issued and backed by the state power. They may exist alongside each other peacefully but killing each other fatally may not be on the menu.
We have to understand that for as long as there is a government they need something that they can control with because control is an extension of power. Take away that control and the government may itself irrelevant so would the government relinquish the control it needs via the fiat money. Of course not.
I also believe that rather than make the government the central enemy, it would be good for the Bitcoin movement to make it a little friend on its side by giving in to some regulations and some compromises so it may not suffer the fate of being banned. Please give my regards to China!
Agree, I've seen this topic many times in different way. I wonder why bitcoin will effect the fiat. Of course bitcoin will not replace the fiat , I will also ask you a question. If there is no us dollars, How do you know the price of the bitcoin ? Bitcoin just like a stock, but you can use it like currency. But it will not change local currency at all.
