This is Nick Szabo.

He’s a cryptocurrency legend who some people believe is Satoshi Nakamoto.

But I'd never heard of him until he broke a 5 year Twitter silence last month. So I spent hours digging into his incredible story.

Here's 7 reasons he’s a bitcoin legend: Image
1. He invented Bit Gold in 1998 (One of bitcoin's direct predecessors)

It used proof-of-work puzzles, timestamping, Byzantine fault tolerance, and a growing chain of cryptographic challenges.

Many of the things bitcoin uses today originated in his design 10 years earlier.
2. He coined "smart contracts" in 1994

His vision: computerized protocols that execute contract terms automatically, eliminating trusted intermediaries.

He is the father of all truly decentralized finance.
3. His core philosophy: "Trusted third parties are security holes"

They limit innovation, hide agendas, and create prohibitive transaction costs.

This principle became bitcoin's foundation for trustless design.
4. He was an original Cypherpunk in the 1990s

He took part in the early Bay Area meetings with Timothy May and Eric Hughes and played a huge part in fighting the NSA's Clipper chip surveillance.
5. The Satoshi mystery

Linguistic analysis by Aston University pointed to Szabo as the whitepaper author. Wei Dai said only "Nick Szabo and me" had the ability to build bitcoin.

Nick denies it. But even if he's not Satoshi, he's clearly one of its intellectual architects.
6. He was an early supporter of Ethereum.

They even named an Ethereum denomination after him (the "szabo"). But he's since turned critical.

His take: "Ethereum's primary use cases are largely external to ETH's market value"
7. His blog "Unenumerated" is a treasure trove

His essay "Shelling Out" traces money's origins from shells to precious metals, showing why money needs to have unforgeable costliness.

He only posts when he has something profound to say. Every post is essential reading.
It’s safe to say that Nick has played a massive role in the work that led to bitcoin’s invention.

To me, his return after 5 years signals bitcoin has reached a critical point where original cypherpunk principles need defending.

It’s good to have another cypherpunk around to offset the suitcoiners.

Bitcoin just hit a historic milestone.

The network's difficulty rose to levels that are the equivalent of 1 zettahash of hashrate for the first time.

Here's how you can reverse engineer hashrate from any difficulty level (most bitcoiners don’t know this) 🧵👇
There are multiple ways to measure bitcoin's hashrate, each with different time windows.

You’ll often see hashrate estimated using an average of different sets of block times, like:
- 144 blocks (~24 hours)
- 1,008 blocks (~7 days)

and even 4,320 blocks (~30 days).
The difficulty-based method uses a 2016-block window which is the same window bitcoin uses to calculate and adjust difficulty.

When miners add more hashrate, blocks come faster, so difficulty increases.

The formula is: Hashrate (EH/s) = Difficulty × 2^32 ÷ 600 ÷ 10^18

Strategy's Q2 earnings just answered the biggest question on Wall Street: are they finally eligible to enter the S&P 500?

And when will they get into the index?

🧵👇
The biggest hurdle for Strategy's inclusion into the S&P500 has been FASB accounting rules which did not allow for bitcoin to be marked at fair value and for the subsequent gains to be accounted for in GAAP income.

But that all changed on January 1st 2025 with new rules.
Bitcoin holdings can now be marked at fair value with gains counted as GAAP income.

Strategy's Q1 2025 delivered $5.8B net income as a result, marking their first positive quarter.

But the S&P500 demands the sum of four consecutive quarters be positive too.

Are you confused about all the different MSTR preferred shares?

You're not alone.

They just announced a 4th preferred stock (STRC) that's different from all the others, and it’s the largest US IPO of 2025!

I'll explain all 4 and what makes STRC unique 🧵👇
First, what are preferred shares?

Think of them as stocks that act more like bonds. You get regular cash payments (dividends) and if the company goes bankrupt, you get paid before regular stockholders.

But you usually don't get voting rights.
Strategy's four preferred shares so far:

- Strike (STRK)
- Stretch (STRC)
- Strife (STRF)
- Stride (STRD)

I’ll go over each one and then cover what makes STRC unique.

MSTY is a fund that markets a 89% yield by selling options on MSTR stock.

You will never find a clearer example of financial engineering fooling people.

This thread is going to piss a lot of people off (but it's true)

🧵👇
MSTY uses a three-pronged synthetic strategy to generate income:

- Synthetic long exposure (long call + short put)
- Short-dated call selling (0–15% out-of-the-money, 1-month or shorter expirations)
- Holds US treasuries

But here’s what's hidden in the small print...
MSTY’s “dividends” are skewing how the average investor perceives the fund's yield.

Since inception, ~55% of all distributions have been returns of capital rather than yield produced by the fund's options strategy. Image

I'm a bitcoin bull, but I have to be honest:

History shows a surprising pattern of price action after major psychological levels.

$10→$100→$1K→$10K→$100K

I analyzed what bitcoin did after hitting each of these, so you can prepare for what might come after $100k 👇🧵
My methodology was simple, so anyone can follow along:

1. Mark first time BTC reaches a milestone price
2. Record last time BTC was at that price
3. Track lowest/highest prices from the milestone price
4. Calculate max % gains and drawdowns from the milestone price Image
$10 Epoch (2011-2012):

Passed in ~1 year. Bitcoin saw a -80% drop to $2 and a +196% gain to $30.

Bitcoin's wild price swings, particularly to the upside, were evident from the early days. Image

My wife would have no idea how to access our BTC if something happened to me.

This inheritance problem alone challenges the self-custody purist position.

Here's a different approach to custody that accounts for human and systemic risks that everyone should at least consider:
2/9 Even I, deeply embedded in the bitcoin industry, find long-term self-custody daunting.

I have calendar reminders every quarter to check my seed backups.

The mental overhead is not that significant, but the stress from being a single point of failure for the family is.
3/9 The most concerning aspect for me is what happens if I'm gone tomorrow?

My wife would struggle to access our bitcoin despite my best efforts to document the process.

In contrast, a custodian would have established procedures for this scenario.
