That was a few days ago. 1AYtn... received 400,000 BTC and then sent 150,000 BTC to 1LYJH... (possibly the same person). 1LYJH proceeds to break the coin into many smaller pieces over a long period of time. My guess is that 1LYJH is breaking the coin intentionally for some reason (maybe anonymity).
There might also be another person (1NMDH
) between 1LYJH and the chain of coin-breaking transactions.
Interesting series of transactions.
One of the 400,000 BTC transactions was only 259 bytes in size, and only one transaction/block, since the 400,000 BTC was already in one coin.
