195K Bitcoin Transaction
First time accepted submitter saidi writes "The Washington Post reports that yesterday a truly massive Bitcoin transaction occurred, from the article: 'In this particular transaction, bitcoins from 15 different Bitcoin addresses were consolidated and sent to address 12sENwECeRSmTeDwyLNqwh47JistZqFmW8. The size of the transaction? 194,993 bitcoins. Given that one bitcoin is worth around $800 right now, the transaction is valued at more than $150 million.'"
A researcher did a bit of digging, and it appears that this was the Bitstamp exchange moving their balance around (business appears brisk).
Was this transaction really intended to be secret? "Leaking" the identity seems like a positive PR move for the exchange --- "look how much BTC we handle, and how hot bitcoin transactions are!". Normal sized transactions are already obfuscated by the traffic of normal sized transactions. How many users have $1e8 bitcoin balances to shuffle around just to provide "cover" for this size of transaction --- as though doing so would improve their ability to keep a low profile?
This is simply good stewardship. One of the largest exchanges (actually not, Bitstamp, rather another ahem Magic: The Gathering Online Exchange site) had a rush of buy orders, so they decided to redeem an address they kept in cold, offline storage to meet demand.
This is a good thing(tm), as it means that there isn't any fractional deposit factoring going on.
