The Complete Guide to Bitcoin: Everything You Need to Know in 2025
1. Introduction to Bitcoin
What is Bitcoin?
Bitcoin ek revolutionary digital currency hai jo 2009 mein introduce hui thi. Ye duniya ki pehli successful cryptocurrency hai jo blockchain technology pe based hai. Bitcoin ko "digital gold" bhi kaha jata hai kyunki iska limited supply hai - sirf 21 million Bitcoin kabhi exist kar sakte hain.
Traditional currency ke unlike, Bitcoin decentralized hai, matlab koi government ya bank isko control nahi karta. Ye peer-to-peer transactions allow karta hai without any intermediary like banks ya financial institutions.
Why Bitcoin Matters in Today's Digital Economy
Digital economy mein Bitcoin ka role bahut important ho gaya hai. Ye financial freedom provide karta hai aur inflation hedge ka kaam karta hai. COVID-19 pandemic ke baad, jab governments ne bohot sara money print kiya, tab Bitcoin ki value significantly badhi hai.
Bitcoin transactions fast, secure aur globally accessible hain. Cross-border payments ke liye ye traditional banking system se kaafi better option hai.
Quick History and Background
Bitcoin ka invention Satoshi Nakamoto ne 2008 mein kiya tha, jo ek mysterious figure hai - koi nahi janta ki ye kaun hai. 2009 mein first Bitcoin block mine hua tha, jise Genesis Block kehte hain.
Initially Bitcoin ki value almost zero thi, lekin 2017 mein ye $20,000 tak pahuncha aur 2021 mein $69,000 ka all-time high touch kiya.
2. How Bitcoin Works
Bitcoin Blockchain Explained
Bitcoin blockchain ek distributed ledger hai jo sabhi transactions ko record karta hai. Ye chain of blocks hai, har block mein multiple transactions hoti hain. Har block cryptographically linked hota hai previous block ke saath.
Blockchain immutable hai - matlab koi bhi previous transaction change nahi kar sakta. Ye transparency aur security provide karta hai.
Peer-to-Peer Transactions
Bitcoin direct person-to-person transfer allow karta hai without any third party. Jab aap Bitcoin send karte hain, to transaction blockchain network pe broadcast hoti hai aur miners verify karte hain.
Role of Miners and Bitcoin Mining Process
Bitcoin miners special computers use karte hain jo complex mathematical problems solve karte hain. Ye process "Proof of Work" kehlata hai. Successful miners ko reward milta hai Bitcoin mein.
Mining process network ko secure rakhta hai aur new Bitcoin supply create karta hai. Currently mining reward 6.25 Bitcoin per block hai.
Importance of Bitcoin Halving
Bitcoin halving har 4 saal mein hoti hai. Isme mining reward half ho jata hai. Ye scarcity create karta hai aur historically Bitcoin price increase hota hai halving ke baad.
Next halving 2028 mein expected hai jab reward 3.125 Bitcoin per block ho jayega.
