What will happen if we use a one currency only?

[mastermold]

 if there is only one currency, than it had to bear the burden of many under-developed economies (and also of some financially defaulted countries like Greece). Hence, the value of that currency would be highly undermined in terms of the performance of those economies which are struggling hard to maintain their status while the same value will be highly overestimated in case of those governments who are just sitting on the couch to gain their salary.

Moreover, a single currency status would be harmful for the markets as well because the Whole gamut of Foreign Exchange (the highest financial market with nearby $5 trillion volume a DAY) will be vanished. The same would also affect some parts of the economy as it would nullify the need of financial sector employees and would generate huge Unemployment.

To sum up, in order to have different delicacies in global environment, generating capacity to pay the hard-workers and punish the weaker economies, together with giving rise to need of Smart Employees, it is better to avoid thinking of single currency.

Indeed, a lot of coutries are intresteon on their own currency and don't wonna allow people to use any other fiat money, not even digital currencies. I think if that will happend it's really hard to say what kind of a price would be that currency. But a lot of currencies are dependent on other ones this which are more reliable and stable on current substantial

Every country have their economy challenge so it's impossible to happen.
Let say if this happen then there will be massive demand for some object let say , laborghini demand will increased 10000% since they able to earn same value just like other country has. If this keep happen than the resource will be vanish more faster than we expected

[webtricks]

The economic balance will turn seesaw, rich countries on heavier side and poors flying above on other side. With same value across the globe, poor countries will unable to access resources as richer do. Will lead to huge economic disturbance and widened gap between rich and poor.

What if all nation use only a one currency or one global currency?, What will happen to our world?, What is the effect of every nation's or every country economy?, It can make people's unite each other?Any opinion.

If that happen many of the bitcoin holders will become happy and for sure the value of bitcoin is definitely reach the peak high price value. And there is a possibility that people around the world unite each other.

[anavuajna]

I think such a condition is not possible even in future.Such a system now exists only in UAE which use Dirhams and European union which uses Euro.A country prints its currencies based on the value of gold it has in reserve and i dont know how all countries would agree to have a single currency.

It seems to me that now there is no gold provision of currency. I do not know how the national currency is supported, but definitely not gold.
Ideas of a single currency existed for a long time, but all of them did not translate into reality

It's not good. If we have only one currency on the world the greedy people will want to control it even more, there is a profecy which says when the new mundial order control the world there will be only one currency controlled by them. I believe Bitcoin is at this point the antagonic currency to the new mundial order wishes. And it's good how it is now, many currencies, many possibilities to the individual chooses.

Currently all the currencies are controlled by some hand, but if we all have one currency then everything would be fine, I mean look at people back when they used gold to buy and sell stuff things were fine you could go anywhere in the world and buy things with the same currency, but look at it now the world is constantly in war.

If all nation use only one currency, it means people around the world are united in one system. Meaning, if this currency is bitcoin the main currency all paper money are not useful anymore, and many people's too are not poor I think and the economy is also level up. And its true people each other are being unite.

[Amadues]

one currency only is impossible. a good example is what nowadays is happening with btc price dumping and most of the top 100 alt coins are gaining value. people will ever want their choice.

[Lecam]

That looks good because if a single currency is just  used to be quite difficult for others and they don't need to exchange currency for another before they have buy there needs. And will be good for everyone because sometimes you need a change of dollars just to have use to other countries.

[darthmaul]

It's really hard to state the consequences. Because there might be positive or negative side both. I guessing it would result in negativity due to complex domination of countries. Many countries are leading entity currently because of their currency. Your currency is gives power to your nation, it's property, it's military forces and protects borders from enemies. Yes! that is what money do. Countries with less of this always get dominated. There are many examples you can see in today's world. If you introduce one currency in the world then there will be first and last world war on the topic "Who will regulate that currency"? 

I am pretty sure no government will want to let this happen due to it's complex future and regulations. They have to save their assets from being monopoly gamed. 

[suredoood]

There are a couple of main reasons (although many more) why most countries have their own currency:

1. Each country wants to be able to regulate their own economy, having their own currency that they control gives them that power.

2. It provides a small barrier between a nation's economy and the global economy. An example of this is Greece with the Euro, though luckily it was contained to Greece as far as I know. If a nation's economy collapses and they have a worldwide currency it could be very bad.

Indeed. It also gives a country its own identity different from other countries. I think having one currency would just to more division and power struggles between rich countries and it may very well lead to military conflicts as to should have control over that one currency

And what about the European zone, which has a common currency and is quite valuable for today. The euro is not national, but it was recognized by all the countries of the European Union. And the dollar is generally considered international and nothing terrible happens. Wars begin for other reasons.

If all nation uses only a one currency, there is a good effect and bad effect for me. The good effect is, there is need to have a money exchanger for you to have a legal currency in other country. We can use currency into country so it will make us easier to buy a thing and to travel anywhere. But the bad effect is, there is no trading will happen so all we is go only in business to earn.

[Mario274]

I think that the most affected traders. Then there will be no stock exchanges, because there will be nothing to trade. I'm not sure that this will bring a positive effect

[Taki]

Well, in the case that all countries will move, for example, on dollar do they want it or not they will have to accept it, and in that case dollar will become international currency. In this case only one country wins - the US. But in the case if bitcoin will be accepted as international currency nobody will be a winner. I don't meen that every cuntry will be a looser, no, I mean that everything will be fair and nobody is going to be first or higher or main or ect. in this case. Sounds good

Dollars and now I go all over the world. For this the Americans have made so that all people have the dollars and not interested in his depreciation. I think as long as there is no currency which can compete with the dollar. This is the key to the success of the American economy.

and to me i think we are going to use a single currency and that will be bitcoin, as  bitcoin is still the number one online currency and still there is not a single currency so close to bitcoin to compete it.
