A guy named Josh predicted months ago that the price would reach $84K on this exact date—and it did.
Now, all of Bitcoin Twitter is swooning over him, asking for more prophecies. He’s saying that from here, we’re headed straight to the moon, all the way to $444K.
There’s a particular obsession among retail investors with predictions.
That’s why PlanB became so famous—people believed he was a prophet.
Now, they have found a new messiah.
Reminds me of last year when a very successful influencer told me: Look, the key to success on Twitter is understanding your audience. Think about the average person’s intelligence level—on social media, the kind of content they engage with always rises to the top.

DeFi platforms deliberately do not highlight the main risk of earning yield:
Your principal is at risk!
Where does the yield they offer come from? From taking risks with your own capital.
If someone understands this simple concept, they won’t lose their money in the bankruptcies of BlockFi, Celsius, Luna, Voyager, FTX and countless similar cases.
Earning yield on idle capital sounds like a great idea—until you ignore the risk to your principal.
If U.S. treasuries or a bank—backed by the full faith of law, courts, and regulatory bodies—pay interest, that’s one thing. But when an unregulated coin offers yield, it’s an entirely different thing.
The real yield in DeFi is you.

In the Javier Milei pump and dump story, one of the most interesting revelations is that Dave Portnoy (a well-known figure in online betting) knew in advance that this meme coin was going to be listed and bought in early.
The meme coin’s creator had been in close contact with him, telling him about his connection to Milei and the token launch. Portnoy himself admitted, “I bought as much as I could in the first ten minutes.” But when Milei backed out and deleted his tweet, everyone dumped, and Portnoy took a loss. Eventually, he and the coin’s creator agreed to reimburse him for his losses.
First, this fool literally confessed to insider trading on Twitter. Second, if you’re trading these kinds of things, pay attention to who you’re up against. The insiders always know when a token will launch—they’re ready to buy before you and dump before you. The game is rigged against you from the start.

Reflections on altcoins and the Bitcoin maximalist movement
Bitcoin maximalism was a reactionary movement to the unbearable magnitude of fraud and grift that existed in altcoins.
Many are prior altcoiners who got burnt and learned a hard lesson.
Most maximalists I know have no issue with tech experimentation. The issue has always been the grift of selling tokens that eventually became a casino masquerading as a software business.
And when 99% of an industry is vaporware tokens, the whole category gets rejected.
Interestingly, this intolerant minority has been proven right time and again over the last 16 years.
Every single “next bitcoin” project has failed. Many high-profile anti-maxis (e.g., Mashinsky) turned out to be actual frauds. And most alts disparaged by maxis ended up underperforming Bitcoin over time.
You may not like maxi’s who “blindly” reject the value of the whole altcoin space. But you cannot deny that people who listened to maxis were saved from numerous scams in the space. And they outperformed most altcoins too.
Maxis decided to promote only the thing they cannot print or manipulate. By doing so they closed their own door to grift. When you cannot sell a token little incentive is left for nonsense. Maxis self-selected out of the shade and stayed clean (for the most part) in a dirty industry.
That is not to say everything is cool. As maxis were proven right on many issues, grifters adopted the label maxi to appear legit but are deep down the same old. Some are using the label for marketing without really understanding what Bitcoin is. There are many that I disagree with. I am myself blocked by several big mouth maxi-marketers.
But nonetheless the only safe space in this ocean of grift and fraud is Bitcoin.
I have studied this space since 2015, and I am yet to find a truly viable and sustainable idea in the 1000’s of token that have launched since except in stablecoins.
It has always been about the tokens not the software.
It has always been about the gamble not the tech.
No one cares about the fake use case and utility. Everyone is in for the get rich quick.
In the end, it has become clear to me that alts have always been memes. Memecoins masquerading as tech.
Which are now being replaced by pure memecoins.
In the end, the honest, value-adding, positive sum, incorruptible money wins. And I am happy to have been Bitcoin-only since day one.

Last cycle, I was using my Twitter account to fight scams, and being toxic to ICOs, NFTs, and bad actors in the space. I was a lone wolf; refused to rob shoulders with anyone who was not a 100% reliable bitcoin-only pleb, which is partly why my account was so small.
This cycle, I am taking a more visible role in the space, but still ... man, I want to puke sometimes, seeing the sheer amount of compromised morality. This is largely why I still have not gone to any (=zero) conferences. $Trump coin gave me that mental nausea again.
I am only interested in true Bitcoiners who are laser-focused on fixing the money. If you are a real Bitcoiner, you are my brother, and I want to follow you.

On the anniversary of the Bitcoin ETFs, let's reflect on the crazy things that happened in Bitcoin land in 2024. The sheer significance of what we witnessed :
1) Spot Bitcoin ETFs
On January 10th, the SEC approved multiple spot Bitcoin ETFs, enabling investors to gain direct exposure to Bitcoin through traditional brokerage accounts.
Since their debut, investors have collectively put more than $37 billion into spot bitcoin ETFs. Combined with the surge in bitcoin prices, that’s lifted total assets under management (AUM) in the segment to $107 billion.
The IBIT fund alone has attracted $38 billion in inflows, pushing its AUM up to $52.5 billion.
The ETF grew into a $50 billion fund faster than any ETF in history, and it also holds the record for the fastest ETF to $10 billion in AUM.
2) Price Appreciation
Bitcoin crushed the 2021 ATH and ripped to $100K
3) 180 in politics
The re-election of Donald Trump in November 2024 changed everything. Trump signaled a supportive stance toward Bitcoin, appointing pro-crypto officials. Many members of his admin are Bitcoiners or Bitcoin enthusiasts. Bitcoin is no longer the irresponsible magic internet money for the nerds. It is an asset that the president shills!
4) SEC
Gary Gensler was fired primarily because of his anti-Bitcoin policies. in essence, Bitcoin fired him.
5) Strategic Bitcoin Reserve
A bill was introduced by Sen. Lummis and is strongly supported by the admin to establish a Bitcoin strategic reserve.
6) Corporate Bitcoin strategies take off
Microstrategy, Semler Scientific, Meta Planet, and many more companies add to or establish their Bitcoin treasuries. After many years of Michael Saylor pitching this to the corporate world, in 2024, it finally takes off.
7) Regulated Bitcoin Options
A lively options market opens for Bitcoin ETFs, allowing individuals and institutions to exercise more sophisticated strategies.
There is more, but let's just reflect on the significance of these events .... this was just one year.
Imagine what 2025 will bring.

21st Capital was established in 2024 with one mission:
Assisting individuals and corporations to adopt Bitcoin
We started with advising Bitcoiners on security, wallet setups, and education.
We then quickly grew into a full-service Bitcoin custody service using the most advanced Bitcoin technology. We developed our Smart Vault service, which is a multi-layer multi-sig based on miniscript that finally makes self-custody mistake-resistant and forgiving and natively supports inheritance.
We then developed an analytics arm where we studied Bitcoin data and produced a lot of quant content.
Along the way, we also spoke at numerous events, including the Bitcoin Conference Mena, and appeared on major Bitcoin podcasts.
It was monumental first year. We were so bullish on the company that we did not get investors. We did not burn a lot of someone else's cash and did not allocate a marketing budget. We built it all from scratch.
In 2025, we will 10x our pace. Tune in for several new products and services. https://m.primal.net/NXwB.mp4

2025 is the year Bitcoin will reach $1M. Gradually, then suddenly. The supply is drying up. What does Saylor know that makes him buy faster now? All signs point to an explosion in Bitcoin price.
How do I know? I just made that up. It is cool and more favorable for engagement to out-bullish the last guy. That is the game. You just make stuff up and repeat. If everyone repeats it, it is a real idea.

very good work. one idea is also to break it down by particular periods. For example much of last year's growth was due to ETFs. Then it came US election effect. Would be nice to quantify the dollar effect of each of these events.

Altcoin Daily has taken Saylor words completely out of context in the title and other reporting
He is saying that his “no ETH ETF” prediction was wrong and new administration is pro crypto
Altcoin Daily translates it to a bull Ethereum stance
Desperate.

Many are asking why is MSTR down big.
I have been clear about the possibility of Bitcoin sideways (or bear) causing a crash in the stock.
The mNAV is very sensitive to Bitcoin sentiment. So when BTC loses its upside momentum for a while, mNAV contracts.
So it outperforms both on the up side and the down side. And even in a sideways market mNAV likely contracts.
I did argue this with some MSTR investors and they were thinking the game has changed forever and MSTR will scape Bitcoin downturns. But no! That is wishful thinking.
Just keep that in mind when you invest and don’t just FOMO in. If you feel the FOMO i have a message for you:
MSTR is a machine that converts fiat to Bitcoin. Whenever it outperforms Bitcoin it is like a coiled spring that accumulates monetary energy and releases it slowly into Bitcoin itself (by diluting shares at a premium). So you will end up capturing that premium as a pure Bitcoin holder too.

Already an underground crypto/stablecoin market is forming

2024-12-28 20:05:27 UTC

The Iranian Government shuts down the fiat onramp to crypto exchanges in a hopeless attempt to stem currency collapse.
The Iranian Rial is tanking and has fallen to a new historical low of 800K:1 USD
YTD, it has depreciated by 37% against the USD.
The government had placed various limits on purchases of USD, so people switched to crypto and stablecoins to protect their life savings.
But in their latest move, the government has just closed IRR onramps to crypto exchanges (which as expected has led to an even larger currency fall).
The story of currency collapse unfolds the same way every time.
