Thanks, appreciate it. Will look into it further
So it was the email address someone used to connect this with Craig?

I missed this latest scammery. What's he after old empty wallets for?

Withdraw is a separate function, should be in the menu.

I'll post my thoughts so far here. They may or may not be useful - I hope so.
It looks like blockladder has deleted posts he made in the past. A Google search shows up the odd quoted post for which the original has been deleted. It's hard to tell whether these are sarcastic or trolly. Either way, I've hit a dead end. Here's what I've assumed so far. Some of these assumptions could be false, of course.

Thoughts/Assumptions
1) ‘Why The Comb...’ is poor grammar (it should be ‘Why Does The Comb...’). I assume this is deliberate (OP appears to have native English), and that ONLY these letters are required.

2) I assume it’s an anagram of the question for that reason.

3) The ‘.txt’ is difficult; it could be part of the answer, or could simply indicate that the answer is plaintext. Including ‘txt’ increases the proportion of consonants to a problematic level.

4) I assume that the 8 camel case words are to be hashed (SHA256) to create a 32-byte privkey. It is technically possible that the 8 words ARE the key. However, this would require that several letters were discarded (as the question contains too many), and there is no obvious indication of which ones.

5) ‘Natasha Otomoski’ is an anagram of ‘Satoshi Nakamoto’. The letters were clearly grouped to indicate this, so I assume ‘Satoshi Nakamoto’ is a part of the answer. This massively reduces possible permutations for 8 words. If it is not, and is simply deliberately misleading, it becomes vastly more difficult to figure out the answer.

6) There may be a second layer in the puzzle, whereby the answer references something in the question rather than just using its letters. ‘Why….?’ implies an answer ‘Because...’ (the right letters aren’t present though) or ‘To...’  I spent a while considering the joke, ‘What has teeth but cannot chew’. Answer: A comb. ‘ToChewThe21MbyteHashOfSatoshiNakamoto’ doesn’t hash to the given address.

7) The significance of ‘21’ (or ‘12’, or ‘1’ and ‘2’ separately) in the answer is unclear. The letters aren’t present for ‘21 Million bitcoins’, though they are for ‘21m Btc’.

A rail fence cipher doesn’t appear to produce anything useful.

That's all from me. It felt I was getting close. Assuming there is a solution, I hope this helps someone find it.

I posted this in Slack earlier today:

If you're on our Slack, we'd like to use that to keep people informed over the next few weeks and months. This is the critical moment for Incent, so I hope you will join us.

Should be a simple matter of logging into your account. What is the problem?

You misunderstand. It's possible that the privkey itself is a plaintext phrase like TheCombOfNatashYaddaYadda. However, since only a few such phrases would fit the criteria for a privkey (I think around 1 in 200), you'd need to search a load to get one that worked.
Or you can create any phrase and hash it for a privkey.
Either method generates a valid privkey. But only one will create the privkey to the prize address. So it helps to know what he was doing

Annoyingly, I've hit a dead end.
I'll give it a while longer, then post my thoughts here in case they're of use to anyone else.

Right. Either the 8 words are the privkey (which is possible if OP did some brute forcing - I've done something similar myself, several years ago now, for a puzzle), or it's a hash.
Either way, it's finding the right 32 chars. I have been assuming that they are from the question itself, like others have been.

I don't think it's a troll - I'll give it a little bit more time and then, if I can't solve it, drop my thoughts here.
When you have enough letters to play with, you can make it fit (almost) anything. But the answer I've got so nearly fits the criteria, and reflects the principle hidden between the lines of the question very neatly (I can't say more without giving it away).
But I cannot figure out how it's slimmed down to 32 letters. I am missing something.
Thank you for the tool.

Thanks - BitAddress does the same if you enter a non-valid private key. I've been using that.
It's not clear from the question whether the solution to the riddle is the private key itself, or whether it points to the private key. I don't think it will make too much difference either way but would help - knowing if the answer is 32 letters or not would be useful.

I feel close. I have a solution that matches the right criteria, with the double meaning implied by the question. Just need to figure out how to process it.

Still unsolved? I have a couple of ideas.

Done.

Hoping to be there.

Bitcoin is designed for financial transactions, but that's just information stored on the blockchain. The information can be anything.
The Omni layer is a 'hack' that lets you store other information on the Bitcoin blockchain, and that information records creation, transfer etc of other tokens. Like a blockchain on top of a blockchain.

Think of it like cleaning your ears with the lid of a biro. It's generally frowned upon in polite society and it's not what biros were designed for, but it works well enough and you can't stop people doing it so ¯\_(ツ)_/¯
The Vicks vaporub discussion a few pages back is another example.

Well, that was that. It was, in it's own way, Fabulous. Though 23:10 was a bit much.
Going to need another glass of wine.

I don't know how many minutes of this I'm going to be able to handle. But I have an evening off, and a glass of wine, and... https://www.youtube.com/watch?v=msL-XFs3Ggs

W for Weekly.

April is when Murad expects a bottom. Again, not unreasonable.
The really good news is that the bear line hits zero around August, so we'll definitely be in a bull market by autumn.
