Which is under 5% of the NSA's annual budget. Also keep in mind that
bitcoins are extremely illiquid. The largest bitcoin transaction I
can find where the buyer got something of identifiable value was a
$500K villa in Bali. (The so-called $147M transaction doesn't count
since there's no evidence of goods or services on either side of it.)
Fencing a thousand villas seems pretty hard.
If I wanted to use my NSA connections or my quantum computer to enrich
myself, this doesn't strike me as a particularly good way to go.
R's,
