I just read a story that I can't get out of my head. In the 19th century, in São Paulo, there was a man named Roque José Florêncio, known as Pata Seca. His story is simply fascinating.
The guy was nearly 2.18 meters tall, and the slave owners used him exclusively for reproduction. According to reports, Roque José Florêncio fathered between 200 and 300 children during slavery. After abolition, he received a piece of land, got married, and had nine more children.
But here comes the most incredible part: they say he lived up to 130 years old. When he died, thousands of people attended his funeral

I have always found it interesting to learn more about the founders behind the biggest crypto projects. Anatoly Yakovenko is one of those names that deserved more recognition in the community.
The guy was born in 1981 in Ukraine and moved to the US in the early 90s. Since childhood, he was passionate about programming, a real thing. He spent years working at heavy companies like Qualcomm, Mesosphere, and Dropbox, focused on high-performance operating systems. This infrastructure experience was fundamental for everything that came afterward.
In the early 2010s, Anatoly Yakovenko started explori

Have you ever stopped to think about how many people get involved in crypto projects from the early stages? Pre-launch of cryptocurrencies is exactly that – when you can get tokens before they hit exchanges, usually at a much more attractive price.
The thing is, during this pre-launch phase of cryptocurrencies, tokens are sold at a lower price to raise funds for the project's development. If you believe in the project, you can make a lot of money when it blows up after the official launch. I know people who bought tokens in pre-sale and saw the value triple or more when listed.
The advantages

I noticed that the European natural gas market is in interesting movement. Last week, analysts from ANZ pointed out that despite geopolitical risks in the Middle East, prices are expected to fall more than 4% this week. The issue is that Europe is directly competing with Asia for liquefied natural gas shipments while trying to replenish heavily depleted inventories.
What is currently supporting demand somewhat is the expected temperature drop in northwestern Europe. This slows down stock accumulation and maintains fuel demand. In early trading, the Dutch TTF (market benchmark) fell 1.6%, closi

A recent historical story has been circulating online again, about a man named Roque José Florêncio, nicknamed Pata Seca, a slave who lived in São Paulo, Brazil, in the 19th century. This guy was 2.18 meters tall, chosen by his slave owner specifically for breeding. It is said that he fathered between 200 and 300 children in his lifetime; the number sounds a bit unbelievable, but that’s what was recorded at the time.
The most incredible part is the story that came afterward. After slavery was abolished, Pata Seca acquired a piece of land, married, and had 9 children. Some records say he lived

Whenever the question arises about which country is the richest in the world, most people think of the United States for having the largest economy in terms of total GDP. But here’s the interesting detail: when we look at GDP per capita, the story changes completely. Several much smaller countries surpass the U.S. in this metric.
I started researching this because I realized that many people confuse total GDP with GDP per capita. They are very different things. GDP per capita is basically the average income per person in a country, calculated by dividing total income by the population. It’s a

I was researching tokens on Ethereum and came across this BULL RUN, which seems to have an interesting proposal for those involved in DeFi. The project focuses on facilitating token swaps within the ecosystem, which theoretically increases liquidity. I had never seen something like this with this approach.
What caught my attention the most was the simplified token distribution process. According to what I read, they try to reduce barriers for new projects launching on the blockchain, both on Ethereum and BSC. This could open doors for more innovation, but of course, anything in DeFi carries it

Are you keeping up with what's happening in Africa? There’s a guy who’s really shaking up the geopolitical landscape there: Ibrahim Traoré, the 36-year-old president of Burkina Faso. Seriously, this guy is changing the game in a way few expected.
The interesting thing is that Traoré doesn’t come from the traditional political elite. He’s a geologist, a former artillery officer, and has operated in the most volatile zones in northern Burkina Faso. He has witnessed firsthand the advance of terrorism, persistent poverty, and has started questioning things that many only whisper about: why billion

I'm testing this game Chainers and I found how it works interesting. Basically, when you log in, you automatically get a wallet without dealing with those complicated web3 seed phrases. At the beginning, you receive 6 NFTs and 120 FRI (the game's currency), then you get 3 NFTs and 10 FRI every day just for logging in.
The cool thing is that each login gives you 3 random NFT cards, from common to rare. I’ve been accumulating free NFTs, like the Chainer-hero, to improve my character. The game promises that in the future, you’ll be able to use these NFTs for farming, creating assets, playing, vot

I see that BTC wallets with 100+ bitcoins continue to grow... It's not a coincidence, it's real movement from those who truly have money.
On-chain data shows that these large wallets are accumulating more Bitcoin, a sign that major investors are trusting the market. When whales start gathering BTC like this, it usually means something.
The number of addresses with more than 100 BTC is constantly increasing, and that says a lot about what's happening behind the scenes. While many people get nervous about volatility, these big wallets are quietly buying.
It's like a market thermometer: when you

I found it interesting to note that the altcoin season index is now at 25. Those who follow the market know that this number from CoinMarketCap says a lot about where capital is flowing at the moment.
Basically, what happens is this: they take the top 100 cryptocurrencies by market capitalization, exclude stablecoins and wrapped tokens, and compare their performance against Bitcoin over a 90-day window. If 75% or more of the altcoins manage to outperform Bitcoin, then they declare an altcoin season. Below that, it’s Bitcoin dominance.
With 25, we are far from that 75 threshold. It means only a

Many people ask me if cloud mining is really worth it. Honestly, it's a question that doesn't have a simple answer because everything depends on several factors that most people don't consider before starting.
First, let me explain what it is. Cloud mining basically means renting computational power from data centers instead of buying and setting up all the heavy hardware. The provider takes care of everything—electricity, cooling, maintenance—and you receive your share of the mined coins. Sounds easy, right? But here’s the point: it’s not as simple as it seems.
The main attraction is obvious.

You know, when I first started studying cryptocurrencies, the concept of NFTs was something many people didn't quite understand. But it's actually very simple: NFT stands for Non-Fungible Token, and basically it is a unique digital asset that lives on the blockchain. Unlike Bitcoin or Ethereum, which you can exchange for another without issue, each NFT is exclusive and non-interchangeable.
The history of this is interesting. The concept began back in 2012 with colored coins on Bitcoin, but what really exploded was in 2017 when CryptoKitties came out. You bought unique virtual cats and bred new

I just saw an interesting statement from the Bitwise team about what's happening behind the scenes. According to Matt Hougan, their head of investments, BlackRock is in serious talks with the SEC to tokenize their iShares ETFs. This is somewhat important because we're talking about one of the world's largest asset managers exploring blockchain.
The detail that catches attention is the uncertainty in the timeline. Martin Small, BlackRock's CFO, was very honest: he can't promise it will be out in 90 days or if it will take up to a year. When you have players of this magnitude dealing with regula

February was interesting for those closely following the crypto market. Despite the decline, VCs continued investing — $883 million in startups, according to DefiLlama data. A 13% drop compared to last year, when the market was booming. But what really changed isn’t the volume, it’s the criteria.
Andrei Grachev, from DWF Labs, was very straightforward with me about this: "The era of raising funds with just a narrative and a pretty PowerPoint is over." Now investors want to see real revenue, active users, and reasons to believe the project will survive when the market drops. It’s no longer a ga

I just saw a news story that well summarizes the chaos in state management of cryptocurrencies. South Korea is urgently revising its custody protocols after the National Tax Service accidentally leaked a wallet recovery phrase. Yes, you read that right — a government agency published the access key to a confiscated wallet.
The result? About 4 million PRTG tokens were moved immediately after the leak, with a theoretical value of around $4.8 million. Someone gained access and, interestingly, returned the assets the next day — at least that’s what the police are investigating. But the fact is tha

I just saw an interesting analysis from Glassnode about the Bitcoin market structure. It seems there is a large concentration of put options at the $62,000 strike — like, a lot of people betting that the price will drop to that level. This makes that level very important now, acting as a critical support for BTC.
It's the kind of information that makes us think about where the big players are positioned. If that level gives way, things could get interesting. Anyway, it's worth watching how the price behaves in this zone.

I just found out that World ID made a significant update this week, and I must admit that some details caught my attention. We are talking about 18 million verified users through Orb spread across more than 160 countries, which is quite impressive.
The most interesting thing is to see how they are applying this in practice. The integration with Tinder is a very creative case - it basically offers a "real person badge" to users, which should increase trust in connections. At the same time, they are working with Zoom to detect deepfakes during calls, ensuring that participants are real humans. A

I just saw that Maji took a heavy hit on Hyperliquid. His long position in ETH was partially liquidated, and the accumulated loss has already reached nearly 30 million dollars. Basically a disaster.
Maji was trading with 25x leverage, holding 2,500 ETH, and the liquidation price was around $1,926. With ETH fluctuating around $2,320 now, you can see how tight things got for him. These market movements can be brutal when you're using that much leverage.
It's the kind of thing we see happening regularly on Hyperliquid. Maji had a huge position, and when the market moves against you, liquidations

I just noticed a very interesting movement by JST that deserves attention. The third massive buyback and burn round has just been completed, and the numbers are quite significant.
In this round, 271 million JST were burned, valued at $21.3 million. It seems like a large number, but here’s the important detail: it represents 2.74% of the total supply. The capital came directly from the organic revenue of JustLend DAO — $10.34 million from an accumulated reserve plus $10.97 million generated in Q1 2026.
Now, looking at the big picture, since October 2025 when this program started, 1.36 billion J
