What is Blockchain?

Content:

Blockchain is the technology behind Bitcoin, Ethereum, and most cryptocurrencies. It is like a digital ledger that records transactions in a secure and transparent way.


Each record in the blockchain is called a block, and many blocks together form a chain. That’s why it is called “blockchain.”


The biggest advantage of blockchain is that no single person or company controls it. It is decentralized and cannot be easily hacked or changed.


Today, blockchain is not just used in crypto — it is also being used in banking, healthcare, supply chain, and many other industries.

Title: Blockchain Kya Hai?


Content:

Blockchain ek technology hai jo Bitcoin, Ethereum aur zyada tar cryptocurrencies ke peeche ka system hai. Ye ek digital daftar (ledger) ki tarah hota hai jo transactions ko safe aur transparent tareeqe se record karta hai.


Har record ko block kehte hain, aur jab bohot se blocks jud jate hain to wo chain ban jati hai. Isi liye iska naam “blockchain” hai.


Blockchain ka sabse bara faida ye hai ke isko koi ek shakhs ya company control nahi karti. Ye decentralized hoti hai aur ise easily hack ya change nahi kiya ja sakta.


Aaj kal blockchain sirf crypto ke liye nahi, balki banking, healthcare, aur supply chain jaise fields mein bhi use ho rahi hai.

What is Futures Trading in Crypto?

 🟢 English Version What is Futures Trading? Futures trading is a type of agreement where you buy or sell a cryptocurrency at a set price on a future date. Instead of owning the actual crypto, you are only betting on its price going up or down. For example, if you think Bitcoin’s price will go up, you can take a “long position”. If you think it will go down, you can take a “short position”. If your prediction is correct, you make profit. If it’s wrong, you lose money. How Does It Work? You don’t need to own crypto to trade futures. You only need margin (a small amount as security). Exchanges allow leverage (like 5x, 10x, or even 100x), which multiplies both profit and loss. Settlement happens on the date of contract expiry. Risks for Beginners Leverage can quickly wipe out your funds. Market moves fast; one wrong prediction = big loss. Futures are better for experienced traders, not complete beginners. 👉 Futures trading can be profitable but it is highly risky. Beginners should fi...
