Oh. Do we know of any big addresses supposedly belonging to him?

Yeah but the point is there would be no need to trick people because it was a totally new concept anyway.  Nobody knew that bitcoin would be worth anything.  Its like me saying to you an idea to make money and you rushing off and doing that task based on just an idea - you wouldn't bother right.  Stasohi got to mine legit with no premine because we all didn't know how brilliant the idea was, its beautiful.

The first few versions of the Bitcoin core client had a built in CPU-miner. Most of the early coins that were mined by Satoshi and others were mined using Bitcoin core. The characteristic was that every 50BTC block was mined to a different address (in the same wallet), so there are no big addresses for these early unmoved coins. You just have a bunch of different addresses each holding 50BTC worth of virgin coins.

This whole forum was an announcement thread of Bitcoin.

And I agree  lock this thread. There is nothing you can add to this discussion.

this forum was created 10 months after bitcoin was running. yet many people were talking and bitcoin was open from day 0.. just not here..
stackexchange cypherpunks, sourceforge, mailing lists, IRC were the older communication outlets. this forum didnt even conceive the term "ANN" until the crap coins and pump and dump coins of 2013+

I would not consider Bitcoin a premine. While there were only few earliest adopters, everyone outside was able to join, if he/she wanted. In my opinion the large amount of coins Satoshi presumably mined in the early days are well deserved for the great gift he has given to all of us.

That said it is not even clear, if Satoshi still has access to his alleged wealth. During the foundation times, Bitcoin was more or less considered an experiment, with a single bitcoin worth only fractions of a cent. So there's a significant probability that a huge number of early mined Bitcoin are lost forever due to carelessness of their holders.

I don't see a purpose in knowing where Satoshi's wallet is. He deserves to maintain his privacy more than everyone else here.

ya.ya.yo!
