standardized currency codes?

[zenyfomax1]

Wondering if someone knows of efforts for cataloguing and standardizing cryptocurrency codes. As we all know, currently different cryptoexchanges sometimes use different codes e.g. XBT or BTC for bitcoin, BCC or BCH for bitcoin cash, XLM or STR for stellar lumens, and so on. Also, some of these codes are not ISO-4217 compliant, e.g. BTC clashes with Bhutan currency and so on (see https://en.wikipedia.org/wiki/ISO_4217).

I'm asking this because I'm planning to write a common CLI for multiple exchanges.

the ISO standard for bitcoin is XBT edit[1] only because calling it BTC and starting with B was not possible because of conflict with another currency  but people use and prefer BTC because it is easier to use and it has been used longer.

as for altcoins nobody cares because they are not used anywhere outside of exchanges and inside exchanges they can call it whatever they want and since there are only finite number of letters in English language but infinite number of altcoins it is impossible to even try to make any standard for them. for example BCC is bitconnect and is taken already. but bitcoin cash is also using it sometimes.

I don't believe 'XBT' is a standard. As far as I know, the only ISO 4217 assigned X codes are these:

Bond Markets Unit European Composite Unit (EURCO)	XBA
Bond Markets Unit European Monetary Unit (E.M.U.-6)	XBB
Bond Markets Unit European Unit of Account 9 (E.U.A.-9)	XBC
Bond Markets Unit European Unit of Account 17 (E.U.A.-17)	XBD
Codes specifically reserved for testing purposes	XTS
The codes assigned for transactions where no currency is involved	XXX
Gold	XAU
Palladium	XPD
Platinum	XPT
Silver	XAG

just to clarify, i'm not specifically asking for ISO compliant codes. any kind of cataloging is okay.

I've published my first catalog, based on CMC with some symbols/names changed to make them unique. please take a look and hopefully this is useful to some of us.
