looks like XWT is no longer an option, it was stolen by another altcoin.
*Why not XWC ? non compliant?
* XAL (latin variant meaning?)
Therefore, my order would be:
1. XWC
2. XWT
3. XAL
Glad you keep this alive

updated list of possible currency codes:
XWC -
ISO standards compliant -
WC taken from
WhiteCoinXWH -
ISO standards compliant -
WH taken from first two letters of
WhiteCoinXWT - ISO standards compliant - because it goes along nicely with Bitcoin's XBT codeXAL -
ISO standards compliant -
AL taken from first two letter of
Albus which is latin for "white" - same naming convention as GOLD which has currency code
XAU (from latin "Aurum" for Gold)
WC -
not ISO standards compliant - also has a negative EU/ASIA stigma (water closet/toilet)
WTC -
not ISO standards compliant - also has negative USA stigma (world trade center)
edit: unfortunately XAN is already used by another alt

so XAM which is free
XAM -
ISO standards compliant -
AM taken from first letters of
Albus and
Moneta which is latin for "white" and "coin" - same naming convention as GOLD which has currency code
XAU (from latin "Aurum" for Gold)
we could maybe even get some unofficial voting going on here in this thread to test the waters, see whats the sentiment of community:
1. account older than 5 months
2. to keep it simple, use
(like) for one or more currency code options
3. ranking - sorted by sum of
(like) votes for each option
