Can we stray away from this currency ending with the word coin? There's too many 'coins' lets get a fresh, new name. As with anything else, lets try and keep it simple also:
(I also like some of the more sci-fi-sounding currency names)
Units (UNT or UNIT for short)
Standard Value Unit (SVU or UNIT for short)
Skrill (Already slang for money, SKL or SKRL for short)
Krill (What whales eat, KRL for short)
Stacks (A play on a now infamous scam and already slang for money, STK for short)
Etc. I could literally come up with these for days.
