I don't interpret it as a imminent dump threat. Au contraire, looks like Satoshi has adopted SegWit and moved part of his stash to a SegWit address.
That's bullish!
SATOSHI NAKAMOTO LOVES SEGWIT!
afaik, 1000btc have been sold so far

Do you have specific comments in mind that you would like folks to read? Have you figured out whose coins they are? they were mined in January 2010 and they were never moved until today. O.k? Speculation that they are Satoshi's coins, but possibly not, too, right? What is the significance? Someone mining in January 2010 and got several rewards of 50 coins... what else is there to this story?
JJG, let the troll troll!
It's so unlikely those coins are Satoshi's!
Do you remember the 10,000 BTC pizza guy? laszlo?
1 BTC sent your way you Bitcoin legend

Wow thanks, I do still have access to it. You should never delete a wallet, even if you've spent what was 'in' it.
I appreciate the donations, but nobody owes me anything.. I generated my share and I spent it, it was just at a time when the value was lower, but so was the generation difficulty,
and the block reward was 50.Laszlo
and the block reward was 50.
and the block reward was 50.
How many early miners enjoyed and took advantage from the 50 BTC reward blocks?
THIS IS FUD FROM THIS CASHCOIN SHILL! He can NEVER, I repeat
NEVER prove those coins belong to Satoshi. It can be anyone's.
Fair enough, and i think that I asked the question for anyone to be able to provide some kind of explanation.
I would imagine that in January 2010, there were a lot fewer miners - yet without additional information, it could still be fairly difficult to trace the coins, as you seem to suggest... unless we are able to connect one or more of the addresses with a known address - and I think that more and more sophisticated means are being developed to attempt to trace coins while at the same time more and more sophisticated means are being developed to obfuscate ownership.
We live in wonderful and interesting times, no? And, I am glad to have a decent chunk of bitcoins in order to be in a position to actively learn and interact about these bitcoin related matters while profiting in financial ways, as well.
