The thing is, I'm not. But if you buy legal dollars, it's ~800 +75% (a part of that are 30% or so taxes, the other part are 45% or so retentions that are returned as tax deduction doing the proper paperwork).

I held the retained part as taxes because of high inflation, but that's just me.

You can follow that as "dollar tarjeta"

The blue was near 1350 some time ago and started falling when people began to sell their dollars. Now it is slightly cheaper than buying legal dollars + taxes - retentions.
