It's interesting, but not quite a significant event, there could be many versions of the story that would lead to someone having to move bitcoins mined in 2009 and it would be be almost impossible for us to predict right. Although, it shows how far Bitcoin have come in just a number of years. At the first year of it's creation miners may have generated blocks for fun, with a free actually believing in the concept of the network. And 50
BTC then meant nothing, but not satoshis are worth significant amounts.
If these bitcoins were from the same year as bitcoin was created then most probably this is related Satoshi Nakamoto, but why they are moving this now?
It raises suspicion but it doesn't really tell anything to conclude that.
These coins are not within the same year of BTC's creation... more importantly, they are within about 5 weeks of the first block ever being mined... so there would not have been too many miners within that short of a period of time. Of course, we might not even be able to determine how many miners there would have been within 5 weeks of the first block besides satoshi and Hal finney.. Anyone else claim to be mining at that time or known to have been mining so soon after bitcoin's first block?
Clearly interesting.
Let's say for example it was a block mined by Hal Finney. Then that block could be in control of Hal's estate or one of his heirs. Of course, there are other plausible scenarios in which someone would still have access to earlier blocks and may even want to move those coins... I am looking forward to hearing more about this, if there happens to be any more information that can be sussed out from whatever happens to be currently known or even reasonably inferred from that particular transaction including its source and including speculation regarding how many miners might have been operating at that particular time and would have been in the running to have mined that particular block.
