For sure it will be one someday. As for me bitcoin has a future. And I hope a brilliant future. More that can be imagine from everyone of us which discuss about it. But for the time which can be possible no one can know. There to many unknown factors from which this depends. Make predictions without data and without analysis in not mine so I cannot answer to this question. I cannot do neither any analysis because is impossible. I can tell one factor which is important for the given question. The rules that every Central bank must create to legalize bitcoin. Without those cannot exist any startup and CEO of those. Most of the countries today ignore bitcoin. For what rules can (may) we speak? Or when (in which time) they will be live with bitcoin? Or that, that only in 30 countries of the world (in about 200 which are in all those) is legal. You can find yourself the answer.

This was inevitable. Even the cleanly demagogy of Tsipras cannot impede this. It have no sense to be forgotten the money borrowed to the Greeks. There are no reason to do this. Tsipras must thanks to many times all the European countries which after its dirty behavior (on the one hand was in talking with European countries and on the other declares the referendum inviting his people to reject the agreement for which he was in discussion with them) accepted again to speak with him and to give other money that Greece have the possibility to go ahead and to try to go out from the crisis. Seeing its behavior and the behavior of most of the Greeks I doubt that this can be true in the nearest times. but who knows. Maybe some day in Greece emerge in Grace a fair politician, leader politician which can lead his people without demagogy towards the welfare based in the honest work and not in that with credits and with the money of the others.

Question without answer in a certain meaning. In the meaning that never will be possible to know it for the all the world. It is only one way but even this may not be true because to many countries lies with their data.

Normally would be the sum of the price of all the goods in the market in all the world in one given moment. But in the other one the goods will change (maybe price, maybe amount, maybe variety) and new goods may be in the market. Even not maybe but for sure. So the amount needed need to be changed.

Normally within one nation are predictions that predict the amount of currency in the market in with those are occupied the economist. And are the monetary policies (applied by them) which determines the amount of currencies in a certain period in a country. To speak about those is not easy and cannot be a post that can be enough for that. If you want to learn a little more you can read this: https://en.wikipedia.org/wiki/Money_supply

It is an amazing article which bring in attention of everyone the qualities and the unique of bitcoin as an invention and as an currency. Anyone who want to know everything about bitcoin must read it. Congrats for the choice.

Then, since I like your choice and I think that you can be interested to everything regarding bitcoin (even very strange things) I want tu suggest you to read the main post of this thread and if have desire, comment it: https://bitcointalk.org/index.php?topic=1191118.0

Bitcoin in backed primarily by its quality (what derives from the quality which have the technology from which it was invented) and is the peer to peer. In other words bitcoin is an currency which is the materialization of one concept which allow to exclude one third part in one communication between two sources. This is an extraordinary achievement. Then is backed by the passion, interest, curiosity and faith as a new kind of currency by the people.

First of all gambling spend money and don't give money. To gamble you must spend. But is this not the problem. It is the advice. It is the worst advice that can be given. It is the worst way to use your money. I don't understand how can be possible to invest in dice site. Only to play in it. And if you will play one day for sure you will lose all your money.

If you have time, have ideas, are expert in something connected with bitcoin, you can earn some bitcoins join signature campaigns. Go to the section "services" of this forum and there you can find to many sites which pay if you put their publicity as a signature in your profile. The bitcoin earned are few but not nothing. You must have fun doing posts and read the posts of the others to discuss about the matters they write otherwise you will find very hard to do this "job".

This is not an investment or a way to invest but a way to learn more about bitcoin and to earn some bitcoin. Maybe you can have interest about it in the free time.

Neither the first and nor the second one. Bitcoin is important for me but is excessive to pretend those qualities from it for my life. But if it will be possible to happen one of both qualities, probably will be the second one. This can be verified if some day, in some way, I will have (legitimately  ) a big amount of bitcoins. And since I believe that one day (I don't know when) the price of bitcoin will go very high, this will help to much my life.

While I don't see in which way bitcoin can ruin my life. I hate the gambling (which "eat" money) and I don't know other way how to spend those (if I would have). I don't know even other ways in which bitcoin can be ruin the life except the gambling. So no possibility to ruin my life from bitcoin.

It is not a religion but a passion yes. And this is not few. And the most used from all the other coins. Even from big "lions" of market like Microsoft or Dell. But I agree with you. If the new coin will be more competitive for sure will be used more. As I told in my post I don't have knowledge about the new coin.

Now everything is clear. I can have only the first of cards. My country enter in the group in which can be taken only these cards. This fee is to high for me. I have not continuous and big earnings in bitcoin to withstand this fee. Hope to be able to use it in the future. So to have big earnings in bitcoin. 

Thanks for the explanations. Are logical, complete and helpful for someone who have in mind to do this transaction. Some of you answers was imagined (knew) by me (the last two). But it was my curiosity for the answer of the OP who made me wrote those. Me for sure don't have (had) in mind to do such transaction. If I had those money wouldn't stay in front of my computer all the day but will do even some other things (more diverse). 

Since I like your post I want to know your thoughts (if you want to do this naturally) for another my post. You can find that here: https://bitcointalk.org/index.php?topic=1191118.0

Yet I am not clear. I wanted to know if it is a fee that is taken every time I withdraw money from any ATM or is taken only one time when I will take the card.

I would do with pleasure this but must be Marco who must tell this. In this way can be official. Then, I think that if I change signature of the bot immediately the bot will do the payment of the new signature and not the old one. So the posts that I will made since this moment will be paid with the rates of the Hero and not with the rate of Senior. For this reason needed to know what will tell Marco.

I am Hero Member from this moment. I must change my signature (from Senior to Hero) immediately or I must wait that pass the first week? Thanks!

The main purpose of existing of this forum is to talk and discuss about bitcoin and everything which can be correlated with it. So, your post to write for the economy of Vietnam is inappropriate. It have meaning only if we talk about the correlation of this economy with bitcoin. In this direction we can say that bitcoin is banned in Vietnam since February, 2014 by the State Bank of Vietnam.

This kind of behavior have nothing to do with power of the economy Vietnam. Since Vietnam have fear from bitcoin (otherwise haven't banned it) is a poor and weak economy which have fear for something that is yet child and is own by no one.

I agree with you. Bitcoin cannot be made as the first currency in any country for to many reasons. But can bitcoin becomes first world currency? What do you think about this? Can you comment the ideas that you can find in this below thread?

https://bitcointalk.org/index.php?topic=1191118.0

I would thank you very much if you will write your comments after the reading.

Really a good idea. I haven't thought it. But I have some questions. Are you sure that the market can afford such transaction? Are in market so many bitcoins? And it will be possible to buy all those immediately? And to sell those immediately? Because if bought or sold gradually the price will increase gradually and will decrease also gradually and this set in doubt the profit.

If you ask to those questions maybe I will do another post.

I wanted to know only if what you have understood is based to some real data or is only a feeling or sensation become from some your yesterday wonder or from your discussion the day before yesterday with your girlfriend.

Seriously: Have you really read something about this? What kind of search have you made? Can you show some title of speeches or any kind of materials you have consulted? It is very interesting find from what depends the change of bitcoin with the other currencies. It will be a surprise for me if the gambling will be this reason, but, if it will be true, the facts cannot be denied and I must renounce from my convictions.

The most stupidity that an human being can do is to connect the "intelligence" of one speech or something like that of Varoufakis which have as a principal purpose of his life the excessive preoccupation with or admiration of oneself with the intelligence of Satoshi Nakamoto which it has created one of most wonderful invention of century and is so modest as to be disappeared and to not enjoy the deserved merits of its invention.

The narcissism of Varoufakis go over everything and first of all is showed with its behavior with all the European leaders in all they meetings. Even he is a poor debtor. No other merits is known as a foreign minister. But he want world recognition. So must be unique in its words with them. Such he was. For something which a shame for its country. To not get back the money taken from the others.

Satoshi Nakamoto has created something that has passionate all the world and find followers and enthusiast every new day which pass. And yet he remain in silence and in anonymity. Who can imagine the honors that he will and can receive from everyone if will be shown? Yet him remain hidden.

Can everyone who will read this post the stupidity of this comparison?

And then the other shame. The title of "the speech" of Varoufakis with capital letters. The glory of something dirty and shameful. Glory to one people that vote to not give back the money to the owners. Money that made them rich and doing "la bella vita" without working and without doing nothing.

I have no other words for this thread.

Now everything is gone (almost for the moment) so don't exist more such risks for the euro but the if Greece or some other country of Eurozone will go out of European countries which use euro as their currency, euro will suffer to much. It were be in discussion even its existence. Were and yet are to many the articles in internet that explain in details this event. In this point of view I think that if Greece would be already out of Eurozone the value of euro will be decreased, notably with the main currencies (such us dollar, British pound, Swiss franc and Japanese yen). As for being better without Greece I have my doubt. Even I am very critic with them about to many things and with their behavior in these times.
