今天看到4900万刀/BTC这个关于价格的说法，觉得很是离谱，虽然我们都知道在金融市场，价格是围绕价值上下波动的，而且价格对价值的偏离经常也没谱儿，但4900万…我还是表示理解不能，希望Michael Saylor在方便的时候还是能简单介绍一下他的估值模型。
搜索了一下，原来我自己也还从来没在这里聊过BTC的价值估算。
这里简单透露一下结论吧，BTC的价值将要经历下面一些主要估值关口
15.2万USD/BTC
28万USD/BTC
36万USD/BTC
61万USD/BTC
248万USD/BTC
1270万USD/BTC
刚刚说过，价格围绕价值波动，所以实际价格走势不是简单的触碰到价值然后就反转，而是必定过冲，然后折返，长期事后观察就会看到上述几个关口的枢轴作用。
这其中，1270万刀是个类似于无限逼近的价值上限，当然价格一定也会突破这个上限，然后被拉回，收敛于1270万，但是接近价值极限的情况下，市场参与者的情绪几乎不可能将这个价格偏离打到超过20%-30%，任何超过1650万的价格预测，我都有理由质疑其没有有效的模型支撑，纯属信口开河语不惊人死不休。
给出以上结论的估值模型，是以币本位观点计算，然后按美元通胀历史数据计算美元汇率，将在价格触及每个关键价值节点时重新进行修正计算。

My original words are about a method:
1. among the 2048 words in BIP-39, cut the first 4 letters out first
2. delete all the words containing these 10 letters, leaving only about 600 candidate words.
3. to uniquely express 12 seed words, each taking the first 4 letters requires 48 letters. Only 46 are given here, so there are 2 words that are 3 letters long, and there are 10 words are 4 letters in length.
4. run a letter counting program for random combinations of 12 words on the compiled 600-length word list
It's hard to understand from these words that all seed words longer than 4 letters are excluded, right?

Let's take an example
you have 12 seed words in the following order:
anger animal check effort eight episode just oppose pig possible question sea
By the way, this happens to be one set of possible solutions to your challenge.
I re-encrypted them with my password card as below
https://image.nostr.build/3a4d3f8a72c7cfe3ff77eaa7d256e1b4743024637b5ef0dad4ac0ba137d6d0ad.jpg
to get the following strings:
h+ike2Tk2hK9!%%+%@7#S9fVhMV^pVMV!h9Tb=2S9&Xe+hs8~npf5eMss
I can write this string of characters on a piece of paper and put it anywhere in the public domain, along with my password card.
If no one else knows the plaintext and substitution rules, then your seed words are safe.
And even you yourself know the plaintext of the 12 words, and you know the ciphertext, and you have this substitution table from my password card, but you still can't backtrack my substitution RULES.
Once you can do that, guess my substitution rules, you can restore another ciphertexts that I have written on paper and made public:
5hK9!spT&=h+Vs%9K9bXh+hY7fM2&8%+X@e9M2fVhMXspVT^h%Ss@2h+XP
You'll find this is another group of MY seed words:
XXXXXX XXXXXXX XXXXXXX XXXXXX XXX XXXXX XXXXX XXX XXXXXX XXXXX XXXXXX XXXXXXXX
By the way, this group of seed words is another set of possible solutions to your challenge.
can you make it?
As you can see, the key to security becomes the RULES, and it's always easier to memorize the rules than it is to memorize individual ciphers one by one, so I use this card to manage all of my high-strength passwords over 8 years, and I'm sure it can be used to keep the seed words safe as well.

In simple terms, the ciphertext and substitution table are publicly displayed, and without knowing the rules, it is impossible to reverse deduce the plaintext. Even if the plaintext, ciphertext, and substitution table are publicly displayed, it is impossible to reverse deduce the rules. I will give an example to illustrate this later.

Brute force is not feasible for this problem. With the current global computing power, brute force can significantly reduce the search range, but it is still not small enough for luck to play a role in a meaningful time.

In fact, the whole method should be put on fire, not just the most secure part. You can send me these 12 seed words in the correct order in a private message, and I will encrypt them using a public substitution table and send the ciphertext back to you. If you already know the plaintext and the ciphertext, and the table, try to reverse the encryption rules.

no, this challenge is to restore the private key from random characters, which is the security foundation of Bitcoin and cannot be challenged
In fact, the painting gives clues to restore the 12 seed words in the correct order, as the author said, this is a simple substitution cypher, it is impossible to restore it by just have the seed plate, and you can't even start guessing with just the painting, only by putting the seed plate and the painting together can you solve the private key.
And as I told the author, the password management tool I have actually used for the past 8 years can also be used for seed word encryption, which allows to publish seed plate and painting at the same time and still be unbreakable

there are too many collisions with just 46 letters, you need to reveal corresponding painting to narrow down the scope

I don't think this information is helpful, in other words, in practice to resist reverse derivation, the attack vectors won't contain this information.

A little guess on it, the 10 letters b, d, k, l, r, v, w, x, y, z do not appear in this character set, therefore, among the 2048 words in BIP-39, cut the first 4 letters out first, and then delete all the words containing these 10 letters, leaving only about 600 candidate words.
On the other hand, to uniquely express 12 seed words, each taking the first 4 letters requires 48 letters. Only 46 are given here. Therefore, there are, and only 2 words that are 3 letters long, and there are 10 words are 4 letters in length.
If this guess is correct, it should be feasible to run a letter counting program for random combinations of 12 words on the compiled 600-length word list, but this may cause collisions, different combinations may produce the same letter count.
FYI.

Basically, I use such a card to manage passwords. Of course, there is no problem in recording the seed words. You can even display the card and the cipher text publicly, and no one can restore the seed words. https://image.nostr.build/04ba7957788a84288b7ea4eb8927b102e0f4b9784dd8bcfadfbf9753b920035a.jpg

I understand that this is a substitution, but the introduction of 44 new symbols is inconvenient for users.
In fact, I currently use a credit card-sized metal card, with a one-to-many substitution table on the card face, and then switch the substitution set through the rules I define, as long as the rules are kept secret, your plaintext will be safe no matter the ciphertext is displayed publicly, or the card face and ciphertext are displayed at the same time. FYI.

天时不如地利，地利不如人和。三里之城，七里之郭，环而攻之而不胜。夫环而攻之，必有得天时者矣，然而不胜者，是天时不如地利也。城非不高也，池非不深也，兵革非不坚利也，米粟非不多也，委而去之，是地利不如人和也。故曰：域民不以封疆之界，固国不以山溪之险，威天下不以兵革之利。得道者多助，失道者寡助。寡助之至，亲戚畔之；多助之至，天下顺之。以天下之所顺，攻亲戚之所畔，故君子有不战，战必胜矣。
