In another thread there was such a discussion: You can't purchase anything in US with euro, but it does not render euro worthless. All you need to know is that someone on this planet accept this currency as payment, then it should have some value. In fact, you might know nothing about euro, it might just collapse quickly because of those problems in southern europe, but as long as you can exchange it to USD, it has value...
A reasonable person, living in US, who knows nothing about euro, would not accept euro as payment.
At the very least, he has to know the exchange rate, and have *some reason to accept it instead of the dollar.* Otherwise, both bitcoin & euro are out of luck.
In this sense, bitcoin is no difference than any foreign currency of a country that you have never been to.
I'm not in the habit of accepting money from places i've never been to, especially if i know that *that place does not exist.*
Just knowing that some people on this planet accept payment for this currency is enough, it is not necessary to use it to purchase anything around you, all you need is an exchange
Well, no. You need a *good* exchange. One which is local, convenient, fast, and guaranteed to be there tomorrow. Bitcoin exchanges fit none of those criteria.
And, just like USD still keep its value without gold backing it, as long as you can exchange a foreign currency to your local currency with a good rate, even no one in the world accepting payment with that foreign currency, you don't care
The only concern might be: If the people accepting that currency getting less, its exchange rate will drop. But the forex exchange rate is mostly affected by central bank's monetary policy, their rate decision and even market intervention. Comparing with their influence, the real economy's affect on exchange rate is very small
We all saw that when one country greatly increased money supply, the other country would immediately increase their money supply about the same scale, otherwise their currency would rise sharply in exchange and heavily hit their export
For those foreign currency traders, bitcoin is a foreign currency which has a superior property: Downside risk is always limited due to limited supply, in worst case you end up buying all the coins at $100 with a capital around 1 billion USD. But the upside potential is unlimited.
In worst case the worth of a bitcoin bought for $100 becomes 0. Zero. Nothing. Consider bitcoin clone coins that died. They too had limited supply.
Wha happened?
This great property will surely attract lots of currency traders, it's almost a no risk strategy to always go long and double down until they bought all the coins, if that will ever happen
All i can say is please, for the love of everything that's good, kind & fuzzy -- *do not trade in bitcoin until you learn that Martingale is for rubes!* Lawdy.
