The Concept of Cryptocurrency 

A cryptocurrency is a digital or simulated form of currency. This form of money is code-protected by cryptography, and this code protection is tough to decode and break thereby a fraudulent activity, or a dubious transaction is nearly impossible with cryptocurrencies. In the world, there are almost 3000 cryptocurrencies, and the major ones are tokens, altcoins, and Bitcoin.

Most of the cryptocurrencies are decentralized system, built on blockchain technology. A blockchain system is nothing but a cumulative record of all transactions, archived in a public ledger book. Each sale is called a block, and every time a new deal takes place, it is recorded in the Blockchain System along with the recent transactions.

Bitcoin-The Popular Cryptocurrency

One of the most popular cryptocurrencies, Bitcoin, is globally acclaimed as the original and most widely used cryptocurrency. It was introduced in 2009 as a secured open-source software. Under the pseudonym Satoshi Nakamoto, a mythical person brought Bitcoin into the world of global crypto transactions.

Like all other cryptocurrencies, Bitcoins also work using the blockchain technology, Bitcoin makes the users engage in explicit and authentic peer-to-peer transactions. These transactions are achieved via an algorithm in the mesh of blockchain, so every user can see and analyze the same. However, even if every user can see and experience the Bitcoin transactions, discretely it is the owner of that Bitcoin who can decrypt the private key, allotted to each owner, and can engage in sales and training.  

Unlike a bank, there is no omnipotent power to regulate the transactions. It is the bitcoin users who govern all kinds of Bitcoin transactions. No owner reveals their name and identity but functions on behalf of the secret code or pseudo name assigned to them.

Functions of Bitcoin Wallet

Primarily the Bitcoin works with its wallet. It is nothing but a program, a service, or a device that has multiple functions like preserving the public and individual keys, signing information, facilitating transactions, and encrypting. There are various forms of Bitcoin wallets, and some popular ones are as follows.

Paper Wallet

The most natural and straightforward form of Bitcoin wallet is a paper wallet. Fundamentally it is a document or a record that comprises of public details receiving Bitcoins keys and helps one to trade, transfer and spend Bitcoins. Available in the form of QR codes, these wallets are user-friendly as one can promptly scan and engage in a transaction. The keys received in the portfolio can be printed in a tamper-resistant form or can be embedded in a holographic tag for seamless operations.

In the paper wallet is the keys are deposited offline, thereby it is safe and secured as the hackers, scammers, and malware functions cannot get access to the portfolio and conduct any duplicitous activities.

Still, one needs to be extra alert and take some necessary precautions. To evade out the menace of any spyware stalking the wallet creation process is strictly advised to use a new operating system. Moreover, the user needs to check the functionality of the website by visiting, for seamless and safe generation of keys.

Physical Bitcoin Wallet

It is slightly risky and quite unusual these days. With preloaded fixed amounts of Bitcoins, this looked like a credit card and later shaped like a circular medal. The pre-fixed value of this physical Bitcoin cannot be spent until the private key is concealed, and the key is protected and kept safely by a tamper-evident cap.

Mobile Wallet 

Mobile wallet is the most popular and prevalent one, particularly among the active and regular Bitcoin users. There can be people buying things online with Bitcoin or making transactions for bookings and them; this is the best solution. Mobile wallet functions smoothly on any interface of smartphones. With the ease of paying directly from the mobile or by endorsing the ‘near-field communication’ function, mobile wallets can be put into use without disclosing any confidential information about the user.

Though Bitcoins are the rule of the day and the new trend, they are volatile, risky, and prone to hacking and cyber-attacks. Moreover, as the names of the users are coded, it is the best way out for illegal traders to trade prohibited drugs and other banned substances. For all these loopholes, the question of universal acceptability of Bitcoins is still doubtful.
