FAQs: What Is Bitcoin?

Bitcoin is the first-ever globally decentralised cryptocurrency currency. For all intents and purposes, it is the native currency of the Internet.

This write-up is the long and short of Bitcoin, where we delve into frequently asked questions (FAQ) about Bitcoin.

Among other things, this means that bitcoin is completely digital and does not exist in physical form.

It can be sent quickly and securely from anywhere in the world provided the two locations have an internet connection. Since it is decentralised and not controlled by any institution, Bitcoin’s price is determined by free market forces and subject to supply and demand economics; which are in turn coloured by bitcoin’s economics.

Bitcoin is stored in digital addresses that exist on the internet. It is a cryptographic coin which is based on encrypted technology, often referred to as blockchain technology. Since it is decentralised, the currency is not controlled by any central authority like a government or bank.

The project is completely open source and thousands of developers have contributed and continue to develop Bitcoin code on a daily basis.

Who created Bitcoin?

During the global economic crisis in 2008, also referred to as the sub-prime, someone or a group of people nicknamed Satoshi Nakamoto decided that this event was the right moment to release the first ever decentralised digital currency.

On October 31, 2008, Bitcoin was introduced with the release of the whitepaper, titled Bitcoin, A Peer-to-Peer Electronic Cash System, written by Satoshi.

The Pseudonym, Satoshi Nakamoto keeps the true identity of the Bitcoin inventor hidden, and it remains unknown to this day. While some have claimed to be the creator, none of them have provided conclusive evidence and have been dismissed for a variety of reasons.

During the nascent years, Bitcoin has nearly no monetary value. Still, a community of active members eventually found the project and began improving the original code using Bitcoin improvement proposals (BIP).

In 2010, Satoshi left Bitcoin development and his last known communication dates back to April 2011 – an email conversation.

In the years that followed,the community continued to grow as more individuals began looking at sound money principles and assets which lived up to those values.

Who controls Bitcoin?

This is a frequently asked question (FAQ). In traditional finance, it is thought that a bank, government or entity must stand behind a currency in order to ensure economic stability.

In the 21st century, this is no longer the case. A few decades ago, the Debt-based economy began to take shape, in which central banks were able to print money without any link to tangible assets (like gold).

By doing so, central bankers created a spiral of inflation, such that the purchasing power of fiat currency eroded over time. It should be noted that before this era, money was not controlled by the state or central banks.

Bitcoin is a return to this state of affairs, and gives every individual with an internet connection complete control over his or her money.

The Bitcoin Blockchain

What is the Bitcoin Blockchain? This frequently asked question (FAQ) is among the biggest barriers to entry that potential bitcoiners must grapple with.

In the simplest terms, the BTC blockchain is merely a digital ledger that includes all of the transactions in Bitcoin’s history, and it is divided into blocks.

Full nodes (computers) are scattered all over the world and contribute to the ledger’s maintenance and security. This is done through a process that keeps the integrity of the ledger using the SHA-256 cryptographic algorithm.

Anyone can create a node to help preserve the blockchain.

Consequently, Bitcoin is decentralised, so no single entity, be it a bank, a company, or a government, can force the network into doing something. In fact, Bitcoin is never offline.

Who is eligible to create a Bitcoin account?

Unlike the banking system, which chooses who can and cannot use financial services, anyone can create a Bitcoin wallet.

This brings many benefits, the most important of which is easy accessibility and censorship-resistance.

The difference between fiat currency systems and bitcoin is palpable. Banks create policies to which customers must oblige, despite having done nothing wrong. If a client fails to submit to such policies, banks have the authority to shut down their accounts, reverse or freeze payments or any manner of things which is outside of the individual’s control.

This cannot happen with Bitcoin because the user is the sole authority controlling his funds.

In terms of accessibility, anyone in the world with Internet access can obtain, send, store, and transact with Bitcoin. Anyone can open a ‘Bitcoin account,’ so to speak, which is basically downloading a digital wallet app.

Sending large amounts of bitcoin is also a lot faster and cheaper than sending fiat. On April 1 2020, 161,500 ($1.1 billion at the time) Bitcoin were sent in a single transaction. The transaction cost 0.00010019BTC (about $0.68 cents at the time).

Minting new Bitcoin. What is Bitcoin mining?

Bitcoin mining is a process that ensures network security and that new bitcoin enter circulation in accordance with the protocol’s inflation rate.  Whenever Sarah wants to send Bitcoin to Bob, she creates a transaction and signs it with her private key and then broadcasts the payment to the network.

At this stage, miners pick up the transaction, validate it and put it into the next block. This is in turn broadcasted onto the public ledger (blockchain). A blockchain is essentially a chain of data blocks with recorded transactions. As you might imagine, this is where the term blockchain comes from.

When was the first Bitcoin mined?

The first Bitcoin was mined on January 3, 2009. It’s also known by “block number 0” or the Genesis block, carrying a reward of 50 Bitcoins for the miners.

What are miner rewards?

Miners earn two types of rewards – transaction fees for validating the transactions and the second is a block reward.

The miner who manages to solve the aforementioned cryptographic problem receives a block reward, which is the second type of miners’ reward.

As of now, the block reward is 6.25 coins per block and will decrease to 3.125 coins per block post halving (May 2024). Every four years there is a halving event, at which time the reward is cut in half.

So why isn’t everyone mining?

Mining involves solving complex cryptographic problems, based on the proof-of-work hashing algorithm.

In the early days, a personal computer was enough to to mine Bitcoin, but nowadays, as competition has grown exponentially, mining firms are the biggest players that take part in mining Bitcoin.

Notably, the protocol only allows for the creation for 21 million coins, ensuring digital scarcity that cannot be replicated by definition. Once 21 million bitcoin circulate the internet in 2140, there will be no new bitcoins minted and miner compensation will be solely dependant on transaction fees.

This brings us to the next point regarding the advantages of Bitcoin over traditional FIAT currencies.

How do you Buy Bitcoin?

The simplest way to get hold of bitcoin is by buying online or through a mobile application. Of course, it’s paramount to purchase bitcoin from a well-known and reputable provider, such as those used on this site.

How and where to store Bitcoin?

The same way you keep regular fiat coins in your wallet, you can store Bitcoin in a specialised digital wallet. Every wallet has its public address where coins can be received (similar to a bank account IBAN).

Briefly, the address is a string of digits and English letters about 30 characters long. There is no cost to create a wallet and there is no limit on the number of wallets you can create.

Is it safe to send Bitcoin?

Sending Bitcoin is completely safe. A Bitcoin transaction is a digitally signed order that is secure and encrypted. The transaction is signed by the outgoing wallet (sender) and is broadcasted to the network until it reaches the block explorer.

Can I track my Bitcoin transactions?

The Bitcoin block explorer is a public ledger that maintains a live log of all Bitcoin transactions.Each block contains many transactions and log commands and once it is closed, the transaction takes place and funds subsequently arrive at their destination.

How long does it take to send Bitcoin?

When using the native layer one blockchain, it takes about 10 minutes to confirm a Bitcoin transaction. However, this varies depending on the network traffic and the memory pool.

Lightning network transactions are much faster and can be used for quick payments.

What is the cost to send Bitcoin?

The only cost to send bitcoin over the network is the transaction fee, which does not depend on the geography or distance travelled.

This fee is added to every order and paid to the miner for his work to close the block.

The cost of transferring Bitcoin is significantly cheaper when compared to other means of transferring money. However, transaction costs vary in the traditional world depending on the country. Instead of having a fixed fee, most digital wallets offer a set of options to process transactions.

The higher the fee, the faster the transfer the transaction (miners which favour higher fees will process your transaction before others).

To emphasize how cheap it is to send vast amounts in Bitcoin, this transaction of $101,000,000 was sent only for as low as a $121 transaction fee, which is roughly 0.00001%.

Is it possible purchase less than one Bitcoin?

Bitcoin has eight numbers after the decimal point. In fact, the smallest unit of account is 0.00000001 Bitcoin, also known as one satoshi. However, it’s better to avoid sending that amount of bitcoin as the transaction fee would be higher.

Bitcoin use: Who accepts Bitcoin? What can I buy with Bitcoin?

Bitcoin is not the world’s reserve currency yet and is still in the process of mass adoption. However, various payment providers allow instant crypto-to-fiat conversions powered by Visa should the need arise. At the same time, the number of businesses accepting Bitcoin as a means of payment are growing. Just last month, the Spanish opposition introduced a Bill to allow Mortgage payments using Bitcoin and cryptocurrencies. This would require the European country to follow in the footsteps of El Salvador, who have made Bitcoin legal tender by law.

What is Bitcoin Pizza day?

In the hot summer of 2010, when many doubted the very notion of digital money, one of the early adopters named Laszlo Henitz pioneered the crypto payments industry by ordering pizza and paying for it with Bitcoin.

In those days, Bitcoin was worth a few cents, and to order two family pizzas worth $30, Laszlo paid 10,000 Bitcoin.

You might be familiar with the first-ever Bitcoin pizza purchase; which became widely known as the world’s most expensive pizza.

To be exact, 10,000 Bitcoin is worth $461 million in today’s terms.
