Here’s the news—MetaMask and Mastercard have just expanded the card across the entire United States, including New York. Previously, residents of New York didn’t have access, but now they do. The point is that this is a self-custodial card, meaning you retain control over your crypto assets in your wallet until you make a purchase. There’s no need to transfer funds to an exchange beforehand, as with many other crypto cards.
The metal version costs $199 per year, but offers up to 3% cashback on the first $10,000 spent annually. The regular card provides up to 1% in mUSD. Plus, you can earn on u

Here's an interesting coin snap today. Tariffs are rising, and risky assets have taken a hit. BTC is holding around 77.5K, although yesterday they talked about testing 64K. SOL is losing more than others, while stablecoins are reacting somewhat sluggishly, adding only 773 million to the supply.
Looking at the numbers — ETF withdrawals have reached 3.8 billion over the year. Funding has changed direction, and the basis has decreased. When you do such a coin snap of the market, it’s clear that open interest is very unstable. All the pressure from tariffs simply overwhelmed it.
In fact, if you do

I just noticed an interesting movement in the market — implied Bitcoin volatility suddenly jumped from 38.5% to 53.1% amid geopolitical tensions. It sounds dramatic, but if you look at historical data, it's not such an extreme level.
Matrixport noted in their analysis that similar implied movement indicators were seen back in November 2025 — then it was 52.2%. And if we recall February 2026, there was a massive spike up to 65.4% during a major sell-off. So, what’s happening now is more of a normal market reaction.
Interestingly, the cryptocurrency market did not panic sell, as one might expect

It's interesting to watch Robert Kiyosaki once again return to his predictions about a major stock market crash. This time, he more decisively urges investors to prepare by holding what he calls true assets — bitcoin, ethereum, gold, and silver.
His logic is quite simple: when the system is unstable, tangible assets with limited supply become the best protection. In his view, that's why bitcoin with a fixed supply of 21 million coins has such potential. Kiyosaki has long positioned himself as an opponent of the traditional financial system, and his current warnings are based on his book about

Waiting for the Terra Classic update, and here it is at the second stage. The first testing phase of SDK 53 has been successfully completed. This is the update that should bring the chain back to full interaction with Cosmos.
For LUNC and USTC, this is truly a critical moment. SDK as the foundation for the entire stack is not just a technical detail; it’s the backbone on which the entire ecosystem will develop. When such an SDK is mainly about stability and reliability, for Terra Classic, it means a real chance for recovery.
Soon, the community will receive a proposal for the budget for the ne

Interesting analysis on how traditional market giants are entering the crypto space. Earlier this year, ICE (, owner of the NYSE), launched cryptocurrency futures settled in dollars based on CoinDesk indices. These include contracts for Bitcoin, Ethereum, Solana, XRP, and BNB, plus the broad-scale CoinDesk 20 and CoinDesk 5 indices.
Why is this important? These futures are cash-settled, not token-delivered. This means institutional investors can gain exposure to crypto prices without the hassle of custodial complexities and spot trading operational risks. Simply put — crypto without crypto pro

Honestly, right now in the crypto community, many are talking about the industry potentially rejecting the U.S. Market Structure Bill if it continues to ignore the specific needs of decentralized finance.
I see that DeFi protocol developers are increasingly disappointed with the current regulatory direction. The point is that the proposed Financial Services and Financial Institutions Bill does not account for the unique architecture of decentralized platforms. This creates a real problem.
Some key points to understand: first, the Financial Services and Financial Institutions Bill was primarily

Honestly, I am currently observing something truly interesting in the market. Bitcoin and the Japanese yen have started moving almost in sync, and this is no coincidence. The correlation of rates between these assets has reached levels rarely seen before.
Some time ago, this was not the case. Previously, BTC moved according to its own logic, and JPY — according to its own. But lately, these correlations have become so noticeable that they attract the attention of serious market players. When the yen weakens, Bitcoin usually rises, and vice versa.
Why is this happening? A lot depends on Japan’s

I just learned about a pretty serious hack of the stablecoin Resolv. After the attacker discovered a vulnerability in the minting contract, they created 80 million fake USR tokens and withdrew about $25 million worth of ETH. The price dropped from $1 to 2.5 cents in 17 minutes, then slightly recovered to 27 cents – a 72% decline over a week.
Interestingly, the team initially called it a key compromise, but analysts identified the real issue – structural flaws. The SERVICE_ROLE, a privileged minting account, was controlled by a single key without multi-signature. The contract lacked oracle chec

Noticing how the market reacts to different price levels, I realized that many traders overlook one critical indicator — funding. This is actually a very important mechanism that shows the imbalance between longs and shorts.
Funding is essentially a fee for holding positions in futures. When more traders go long, the funding rate becomes positive, and longs pay shorts. Conversely, if more traders are short, the fee goes from shorts to longs. The system automatically tries to balance the market.
Of course, this fee is charged every 8 hours, meaning 3 times a day. When I analyze charts, I always

You know, I studied the market for a long time before I understood one simple thing: most traders lose money not because they don't know technical analysis, but because they don't understand how smart money really works.
Smart money is not just about big players. It's about how large banks, hedge funds, and institutional investors manage the market using huge capital. They don't play by the rules of classic TA; they write those rules themselves. And while ordinary traders look at indicators and patterns, the big player already knows where the market is headed.
Look, traditional technical analy

Many of us listen to music on YouTube, but streaming isn't always convenient — it requires an internet connection, which quickly consumes data. That's why I often convert YouTube videos to MP3 to listen to my favorite music offline. It's really easier than it seems.
Why should you do this? First, MP3 files take up significantly less space than video files. Second, they drain the battery less. If you're creating a playlist for workouts or compiling podcasts for the road, converting from YouTube to MP3 is the perfect solution. Plus, these files work on almost all devices: smartphones, tablets, c
