Testing pseudo-currency "BTC"

[Bost]

Can you please tell me what am I doing wrong? (Thx)

user=> (require '[clojurewerkz.money.currencies])
nil
user=> (clojurewerkz.money.currencies/pseudo-currency?
(clojurewerkz.money.currencies/of "XXX"))
true
user=> (clojurewerkz.money.currencies/pseudo-currency?
(clojurewerkz.money.currencies/of "BTC"))
IllegalCurrencyException Unknown currency 'BTC'

Bitcoin is not part of ISO-4217.

You need to add your own currency provider using Joda Time and Java interop.

Joda Time and Java interop??? I did that in MoneyDataExtension.csv
Except that I found several errors in joda-money mostly revolving
around the concept of pseudo-currency.
Long story told short:
What makes my currency the only-true-one and yours just a pseudo-currency?
The only thing ISO-4217 says is: Currency FOO is standardised,
currency BAR is not standardised.
And the detection standardised/not standardised should not be based on
the count of decimal places of a given currency (rather on something
like being defined in MoneyData.csv/MoneyDataExtension.csv).

I need to talk about it with some joda-money devs. Anyway what do yo
think about that?

Governments do. Welcome to the world of fiat currencies.

The specifics do not matter. There needs to be an indicator of sorts and most "electronic"

currencies don't have a fixed number of decimal places. So it's a good criteria to use.

I think that in the world where probably about 0.1% knows what Bitcoin is,

it is not a problem that Joda Money needs to worry about.

Governments?
So we also need to consider the Governments of Syria, Libya, Zimbabwe etc. ?
And what about Somalia?

Do you realize that you're complecting a notion of "Number of decimal
places" with "Currency defined by ISO norm"?

Ah statistics... :)
I think that in the world where probably about 0.2% knows what Java is
and where about 20% of those know what Bitcoin is, IT IS a problem

that Joda Money needs to worry about.

Well, my original intention was to use clojurewerkz/money for my project.
And now I see I should think twice about that.

You are putting too much thought into this. The Clojure community should focus

less on decomplecting and more on writing quality libraries with documentation.

This argument is a red herring. 100% of the world knows what fiat currencies are,

whether they have flaws or not. So Joda Money focuses on those.

No problem. All it takes is adding a currency provider but I see that you would

rather debate what other people are complecting and how the current situation with

currencies and standards is broken instead of just doing that and using a pretty

decent library.
