While sailing a strange sight to see
An actual Currant bobbing past me
In the Sea
An enigmatic Black Currant no less, not the Current of tidal stress
Mathematically complex an unbreakable code
A new form of something I would guess
Matters of Fiat it does erode
Now all is clear I know what it be
No way, could it be, a........... Crypto-Currant-Sea!
