Let's understand cold wallets because the question of where private keys are stored in a cold wallet concerns many who take the security of their crypto assets seriously.
The point is that a cold wallet, also known as a hardware wallet, is essentially a device that keeps your private keys completely offline. That’s where the entire security magic lies.
When you set up a cold wallet for the first time, the system generates a pair of cryptographic keys for you. The public key is what you can share with others, while the private key is your holy grail—it gives you full control over your funds. Th

I noticed an interesting case about one of the most successful internet entrepreneurs of our time. MrBeast has held the title of the highest-paid YouTuber in the world for several consecutive years, and his wealth continues to grow. Back in 2021-2022, Forbes estimated his annual income at $50-110 million, and MrBeast's total net worth was around $500 million. But the most fascinating part is how he built his empire.
It's not just about one channel. The guy has a whole portfolio of YouTube projects: the main channel with over 140 million subscribers, plus Beast Gaming, Beast Reacts, Beast Phila

Wow, Snoop Dogg is back in action! His new NFT collection on Telegram Gifts sold out in half an hour — nearly a million tokens sold, $12 million in revenue. Premium tiers sold out in just two minutes. It’s serious when such volumes move so quickly.
The collection was divided into five difficulty levels. The most expensive Westside Sign (12,000 units at 10,000 TON each, roughly $12,500 per piece at the current TON price of $1.25), sold out in 1 minute and 47 seconds. Low Rider and other categories also sold out quickly. Fans are clearly hungry for Snoop Dogg NFTs, especially if connected to the

Alright guys, I’ve been looking for a decent cheap VPN for a long time—one that won’t leak my data and won’t cost a fortune. Finally, I figured out which options are actually worth paying attention to. ExpressVPN is kind of the king among cheap VPNs for streaming. Yes, it’s not the cheapest, but for $6.67 per month with three free months, you get access to Netflix, BBC, and all that. Servers everywhere—105 countries, can you imagine?
If you want maximum protection and anonymity, CyberGhost really comes through. An 84% discount plus four months free—plus all traffic is encrypted properly, like

An interesting twist in Bitcoin history: it turns out that Laszlo Hanyecz spent much more on pizzas than everyone thought. Remember those famous 10,000 BTC in 2010? Well, according to him, he mined about 100,000 BTC and spent roughly half on various pizzas, while the other half he gave away or sold. He made a few thousand dollars from these transactions, which was enough to buy a new computer.
But here’s the funny part — Laszlo Hanyecz himself considers this pizza not his main contribution to crypto history. For him, a much more significant achievement was porting Bitcoin from Windows to MacOS

Recently, I noticed that many people are asking about BLZ and what it actually is. I decided to look into it and share what I’ve learned.
Bluzelle is a decentralized blockchain platform that functions as a service for data storage and management. Essentially, it’s a solution for DApp developers who need scalable databases. The project started back in 2014 and has since positioned itself as one of the pioneers in the blockchain database sector.
What’s interesting is that with the growing popularity of decentralized applications, the demand for such solutions is only increasing. Bluzelle provide

I noticed an interesting trend in the AI world — when big money meets moral principles, the first isn’t always the winner. Mira Murati’s story is exactly about that.
First, a bit of context. In the tech industry, she followed the classic path: started as an engineer, worked at Tesla on the Model X, then was at Leap Motion, focusing on human-computer interaction. But her real breakthrough began when Mira Murati joined OpenAI in 2018. There, she became CTO and oversaw the development of ChatGPT, DALL-E, Codex — systems that are now transforming the entire industry.
People following her career sa

You know, I always reflect on this day — August 17th — when the entire trading community celebrates its unofficial holiday. The date is symbolic: exactly 27 years ago, one of the most serious shocks to the Russian economy occurred. Black Monday in 1998 — when the ruble collapsed, investors panicked, and the government declared a default on GKO bonds. It seemed like the end of the world for the markets. But it was precisely then that traders showed what they are capable of.
In the midst of the crisis, when everyone was losing their heads, true professionals found opportunities. They analyzed, c

Honestly, I didn’t understand for a long time what a validator is in simple terms until I started learning about blockchain. It turns out, it’s not as complicated as it seems at first glance.
Validators are basically the people who keep an eye on the network. They verify that all transactions are honest, create new blocks, and earn rewards for doing so. Without them, the blockchain simply couldn’t function properly.
What exactly does a validator do? First, they check whether a transaction is valid, whether it has a cryptographic signature, and if it complies with the network’s rules. Second, t

I've noticed that many newcomers to crypto don't quite understand how intraday trading works in practice. I think it's worth exploring this in more detail because it can be a decent way to earn money if you know what you're doing.
So, intraday trading is when you open and close a position within the same day, leaving nothing overnight. The main idea is simple: catch short-term price movements and profit from them. But there are pitfalls. On one hand, you avoid overnight gaps and can work with good liquidity even on small fluctuations. On the other hand, commissions can significantly eat into y

Interesting statistics recently came out — it turns out that the top countries by cryptocurrency are not quite what I expected. According to Triple-A, in 2024, there are already 562 million people worldwide actively using crypto. That’s more than 6% of the planet’s population, just so you know.
The funniest part is that the top countries by cryptocurrency are led not by the ones you might expect. India ranks first in absolute numbers — 93.5 million users, but Vietnam leads in terms of population share with 21%. The US is third in total users, but here it’s more about speculative interest. Viet

I just saw that Powell's speech at Stanford didn't touch on the economy or monetary policy at all. That's kind of strange, considering everyone is expecting signals on these issues from him right now.
Blockchain news reports that Powell's speech focused on completely different topics. Silence on economic matters at such a moment—is it a hint or just a coincidence? Analysts are definitely trying to read between the lines.
It's interesting to consider what this means for the market. Powell's speech without economic comments leaves more questions than answers. Maybe something is being prepared be

I've noticed that many people ask about the double bottom pattern but don't quite understand how to spot it. I decided to look into it in more detail because it's one of the most reliable trend reversal signals.
A double bottom is when the price falls, reaches a certain level, bounces back up, then falls again almost to the same level but doesn't break it. It forms a W shape. Why is this important? Because it means that the bears can no longer push the price lower, and the bulls are starting to take control.
When I look for this pattern, I first identify a clear downtrend. Then I examine two l

Wow — MrBeast's net worth has officially surpassed one billion dollars. Jimmy Donaldson has entered the club of the youngest billionaires, ranking 8th on this list. Honestly, it's fascinating to see how this guy built such a money-generating machine.
His net worth is made up of various sources — it's not just YouTube. Yes, the channel makes money, but that's only part of the story. There's merchandise, which sells pretty well, and a line of food products under his brand. And just recently, news broke about a deal with the streaming platform Amazon — this could be another major revenue stream.

Scalping is one of the most adrenaline-pumping ways to make money in crypto if you're ready for constant activity and quick decisions. If you love riding waves and locking in profits multiple times a day, then this is definitely for you.
What is scalping in simple terms? It’s trading over very short timeframes — from a few seconds to a couple of minutes. The idea is to catch even microscopic price changes. For example, buy BTC at 67,400 and sell at 67,410 — a tiny profit, but if you make 50-100 such trades a day, it can add up to a pretty decent income.
What you need to understand about scalpi

I noticed that many people in the crypto community get confused when assessing the actual returns of their positions. Here’s the point — you need to look not just at the final percentage, but understand how exactly your investments are growing or falling( year after year.
This metric is called the compound annual growth rate, and it really helps you see the real picture. Unlike a simple profit calculation, it takes compound interest into account — when your profit starts generating profit on its own. This is a key point that many people miss.
The formula looks like this: take the ending value,

You know, I've been in the market for quite a while and have seen people lose money on the same schemes repeatedly. One of the most dangerous is when several players collude and start artificially pumping the price of an asset. Here's what happens.
First, there's a pump. The group coordinates mass purchases, creating the impression that everyone is rushing into the asset. They spread tips on social media, write about 'incredible potential,' and post screenshots of profits. Beginners see this, start to FOMO, and buy in. The price soars over a few days or hours. It looks like a miracle.
Then com

You're faced with a question that beginners often ask: what's the actual difference between wallets? Turns out, this is one of the key points for understanding cryptocurrency security.
Let's figure it out. A custodial wallet is essentially a service where a third party holds your keys and manages your assets. Think of it like a bank, but for crypto. You log in with a username and password, and everything works simply and conveniently. Examples include major platforms like well-known exchanges. The main advantage: lost your password? Recover it through support. But there's a catch—you are compl

You know, I recently became interested in how much money MrBeast has, and the results are simply astonishing. The guy has held the title of the highest-paid YouTuber on the planet for two consecutive years. Donaldson is not just a blogger; he's a full-fledged businessman who built an entire empire on content.
In 2021, he earned approximately $54 million, and Forbes predicted that in 2022, his income could grow to $110 million. Journalists estimate his net worth at half a billion dollars. But here's an interesting point — in 2022, how much money MrBeast has became an even more relevant question
