The invisible currency (edit)

[CRNDLSM]

Loopholes were weaved 'were' is kinda weak
as the process of greed so is 'as'
became perfected. 

A web work so subtle
that any rebuttal really liked this rhyme 
would be reflected. And this one, but I don't understand reflecting rebuttals in a web

Never a venture more costly
than the prevention of money this sounds like a second guess, preventing generation of money? creation of money? Spenditure? 
and it seems now third guessing
you've become greedy. Slant rhyme 

Invisible currency, these are all clues, I'm thinking cryptocurrency because we can't see it, but secrets are also a currency, and the fact that I don't have a definitive answer here is like it's invisible, because I could be way off base too.
