However fine tooth comb is not one with 21 teeth on it

Unfortunately I can't be puzzling for much longer because I go to work tomorrow.

I saw above reply a few days ago and said myself: "way should someone search Hal Finney instead Satoshi?". the answer is because some people believe Hal Finney may be real Satoshi. then I said myself again:"what if this user(watashi-kokoto) be blockladder(OP)?", then each of him/her replies may be a clue for us.

His first reply decrypt an slice of the puzzle for us:

Obviously she isn't him, but

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 S A T O S H I N A K A M O T O 8 2 3 9 1 6 11 4 14 13 12 15 5 10 7 N A T A S H A O T O M O S K I

who do you all think is she anyways?

and this reply implies to a Mailing List Archive that includes some mails of Hal Finney:

and in this reply he have a mistake about comb teeth number(20 instead 21):

Every puzzle needs an art piece so I shooped something hope you like it.

EDIT: fail. 20 teeth not 21 I'm tired

EDIT2: fixed

all of these clues are in Bitcoin Mailing List Archive. in this Link you can see a mail from Hal Finney to Satoshi that he mistakingly mentioned the total number of Bitcois 20 milion:

Code:

Congratulations to Satoshi on this first alpha release. I am looking
forward to trying it out.

It's interesting that the system can be configured to only allow a
certain maximum number of coins ever to be generated. I guess the
idea is that the amount of work needed to generate a new coin will
become more difficult as time goes on.

One immediate problem with any new currency is how to value it. Even
ignoring the practical problem that virtually no one will accept it
at first, there is still a difficulty in coming up with a reasonable
argument in favor of a particular non-zero value for the coins.

As an amusing thought experiment, imagine that Bitcoin is successful and
becomes the dominant payment system in use throughout the world. Then the
total value of the currency should be equal to the total value of all
the wealth in the world. Current estimates of total worldwide household
wealth that I have found range from $100 trillion to $300 trillion. With
20 million coins, that gives each coin a value of about $10 million.

So the possibility of generating coins today with a few cents of compute
time may be quite a good bet, with a payoff of something like 100 million
to 1! Even if the odds of Bitcoin succeeding to this degree are slim,
are they really 100 million to one against? Something to think about...

I think the solution of this puzzle may be in the content of this mail.

And this makes me thinks that who is this blockladder guy? He could be "Satoshi" too right? If we browse through the guys' past he created the account on the year 2015, and now he just wants to give us 1 whole BTC to solve the problem year 2019. That's a 4 years gap to post, so I believe that OP is someone really special connected to Satoshi.
