What is Bitcoin? Is it like a stock? Where does it come from? Why has it gone up in value? How and where can you buy them? How and where can you sell them? Is it really legal? Is there a difference between Bitcoin and Bitcoin Cash?
These are just some of the questions people have been asking about Bitcoin and hopefully this article will shed some light on a subject that has gotten a lot of attention lately, but is still fairly misunderstood by a vast majority of people.
Compiled from various resources, here is everything you need to know about Bitcoin.
For starters Bitcoin is not a stock or a commodity it is actually a Cryptocurrency. So to understand what a Bitcoin is, you need to understand what a Cryptocurrency is.
Cryptocurrencies, also known as digital currencies, are a form of digital public money that consists of lines of computer code that hold monetary values. These lines of code are created by electricity and high-performance computers that do complex mathematical computations. They are policed by millions of computer users who are called “miners.” So physically, when it comes to a Cryptocurrency, there is nothing to actually hold.
“Crypto” comes from the word cryptography, the security process used to protect transactions that send the lines of code out for purchases. Cryptography also controls the creation of new “coins,” the term used to describe specific amounts of code.
Governments have no control over the creation of cryptocurrencies, which is what initially made them so popular. Most cryptocurrencies begin with a market cap in mind, which means that their production will decrease over time thus, ideally, making any particular coin more valuable in the future.
What Are Bitcoins?
Bitcoin was the first cryptocoin currency ever invented. No one knows exactly who created it – cryptocurrencies are designed for maximum anonymity – but bitcoins first appeared in 2009 from a developer supposedly named Satoshi Nakamoto who has since disappeared but left behind a Bitcoin fortune.
In November a rumor began circulating that billionaire CEO Elon Musk of Tesla and SpaceX was the actual inventor of Bitcoin. A former SpaceX intern named Sahil Gupta wrote a blog post in which he claimed that Elon Musk was “probably” the inventor of the cryptocurrency because of his deep understanding of economics and cryptography, grip on advanced coding languages, and the fact he is a “polymath” (a person whose expertise spans a significant number of different subject areas drawing
on complex bodies of knowledge to solve specific problems). Musk said this was untrue and that he had actually lost some bitcoin a friend sent to him some years ago because he doesn’t know where it is.
Because Bitcoin was the first cryptocurrency to exist, all digital currencies created since then are called Altcoins, or alternative coins. Litecoin, Peercoin, Feathercoin, Ethereum and hundreds of other coins, 831 to be exact, are all Altcoins because they are not Bitcoin.
One of the advantages of Bitcoin is that it can be stored offline on a person’s local hardware. That process is called cold storage and it protects the currency from being taken by others. When the currency is stored on the internet somewhere, or in hot storage, like a server on the cloud, there is a high risk of it being stolen.
On the flip side, if a person loses access to the hardware that contains the bitcoins, the currency is simply gone forever. It’s estimated that as much as $30 billion in bitcoins have been lost or misplaced by miners and investors. Nonetheless, Bitcoins remain incredibly popular as the most famous cryptocurrency over time.
Why Bitcoins Are So Controversial
Various reasons have converged to make Bitcoin currency a real media sensation.
From 2011-2013, criminal traders made bitcoins famous by buying them in batches of millions of dollars so they could move money outside of the eyes of law enforcement. Subsequently, the value of bitcoins skyrocketed.
Scams, too, are very real in the cryptocurrency world. Naive and savvy investors alike can lose hundreds or thousands of dollars to scams.
Ultimately, though, bitcoins and altcoins are highly controversial because they take the power of making money away from central federal banks, and give it to the general public.
Bitcoin accounts cannot be frozen or examined by tax men, and middleman banks are completely unnecessary for bitcoins to move. Law enforcement and bankers see bitcoins as ‘gold nuggets in the wild, wild west’, beyond the control of traditional police and financial institutions.
How Bitcoins Work
Bitcoins are completely virtual coins designed to be “self-contained” for their value, with no need for banks to move and store the money. Once you own bitcoins, they behave like physical gold coins: they possess value and trade just as if they were nuggets of gold in your pocket. You can use your bitcoins to purchase goods and services online, or you can tuck them away and hope that their value increases over the years.
Bitcoins are traded from one personal “wallet” to another. A wallet is a small personal database that you store on your computer drive (cold storage), on your smartphone, on your tablet, or somewhere in the cloud (hot storage).
For all intents, bitcoins are forgery-resistant. It is so computationally-intensive to create a bitcoin, it isn’t financially worth it for counterfeiters to manipulate the system.
Bitcoin Values and Regulations
A single bitcoin varies in value daily; you can check places like Coindesk to see today’s value. There are more than two billion dollars worth of bitcoins in existence. Bitcoins will stop being created when the total number reaches 21 billion coins, which will be sometime around the year 2040. As of 2017, more than half of those bitcoins had been created.
Bitcoin currency is completely unregulated and completely decentralized. There is no national bank or national mint, and there is no depositor insurance coverage. The currency itself is self-contained and un-collateraled, meaning that there is no precious metal behind the bitcoins; the value of each bitcoin resides within each bitcoin itself.
Bitcoins are stewarded by “miners,” the massive network of people who contribute their personal computers to the Bitcoin network. Miners act as a swarm of ledger keepers and auditors for Bitcoin transactions. Miners are paid for their accounting work by earning new bitcoins for each week they contribute to the network.
How Bitcoins Are Tracked
A Bitcoin holds a very simple data ledger file called a blockchain.
Each blockchain is unique to each individual user and his/her personal bitcoin wallet.
All bitcoin transactions are logged and made available in a public ledger, helping ensure their authenticity and preventing fraud. This process helps to prevent transactions from being duplicated and people from copying bitcoins.
Note: While every Bitcoin records the digital address of every wallet it touches, the bitcoin system does NOT record the names of the individuals who own wallets. In practical terms, this means that every bitcoin transaction is digitally confirmed but is completely anonymous at the same time.
So, although people cannot easily see your personal identity, they can see the history of your bitcoin wallet. This is a good thing, as a public history adds transparency and security, helps deter people from using bitcoins for dubious or illegal purposes.
Banking or Other Fees to Use Bitcoins
There are very small fees to use bitcoins. However, there are no ongoing banking fees with bitcoin and other cryptocurrency because there are no banks involved. Instead, you will pay small fees to three groups of bitcoin services: the servers (nodes) who support the network of miners, the online exchanges that convert your bitcoins into dollars, and the mining pools you join.
The owners of some server nodes will charge one-time transaction fees of a few cents every time you send money across their nodes, and online exchanges will similarly charge when you cash your bitcoins in for dollars or euros.
Additionally, most mining pools will either charge a small one percent support fee or ask for a small donation from the people who join their pools.
In the end, while there are nominal costs to use Bitcoin, the transaction fees and mining pool donations are much cheaper than conventional banking or wire transfer fees.
Bitcoin Production Facts
Bitcoins can be “minted” by anyone in the general public who has a strong computer. Bitcoins are made through a very interesting self-limiting system called cryptocurrency mining and the people who mine these coins are called miners. It is self-limiting because only 21 million total bitcoins will ever be allowed to exist, with approximately 11 million of those Bitcoins already mined and in current circulation.
Bitcoin mining involves commanding your home computer to work around the clock to solve “proof-of-work” problems (computationally-intensive math problems). Each bitcoin math problem has a set of possible 64-digit solutions. Your desktop computer, if it works nonstop, might be able to solve one bitcoin problem in two to three days, likely longer.
For a single personal computer mining bitcoins, you may earn perhaps 50 cents to 75 cents USD per day, minus your electricity costs.
For a very large-scale miner who runs 36 powerful computers simultaneously, that person can earn up to $500 USD per day, after costs.
Indeed, if you are a small-scale miner with a single consumer-grade computer, you will likely spend more in electricity that you will earn mining bitcoins. Bitcoin mining is only really profitable if you run multiple computers, and join a group of miners to combine your hardware power. This very prohibitive hardware requirement is one of the biggest security measures that deters people from trying to manipulate the Bitcoin system.
They are as secure as possessing physical precious metal. Just like holding a bag of gold coins, a person who takes reasonable precautions will be safe from having their personal cache stolen by hackers.
As mentioned earlier, your bitcoin wallet can be stored online (a cloud service) or offline (a hard drive or USB stick). The offline method is more hacker-resistant and absolutely recommended for anyone who owns more than 1 or 2 bitcoins but it is not without risk.
More than hacker intrusion, the real loss risk with bitcoins revolves around not backing up your wallet with a failsafe copy. There is an important .dat file that is updated every time you receive or send bitcoins, so this .dat file should be copied and stored as a duplicate backup every day you do bitcoin transactions.
Security note: The collapse of the Mt.Gox bitcoin exchange service was not due to any weakness in the Bitcoin system. Rather, that organization collapsed because of mismanagement and their unwillingness to invest any money in security measures. Mt.Gox, for all intents and purposes, had a large bank with no security guards, and it paid the price.
How do I turn Bitcoins to Cash?
You can exchange your Bitcoin for cash either online or in person.
To exchange Bitcoin online, you have three options at your disposal:
1. Debit cards. There are multiple existing debit card programs. For a list of recommendations, click here to visit Cryptocurrency Help.
2. Trading with an online exchange. Some of the more popular ones include: coinbase, cex-io and kraken.
3. Directly trading with another person.
To sell Bitcoin in person, all you have to do is scan a QR code on another person’s phone in exchange for cash and the transaction is complete.
Abuse of Bitcoins
There are currently three known ways that bitcoin currency can be abused.
1. Technical weakness – time delay in confirmation: bitcoins can be double-spent in some rare instances during the confirmation interval. Because bitcoins travel peer-to-peer, it takes several seconds for a transaction to be confirmed across the P2P swarm of computers. During these few seconds, a dishonest person who employs fast clicking can submit a second payment of the same bitcoins to a different recipient.
While the system will eventually catch the double-spending and negate the dishonest second transaction, if the second recipient transfers goods to the dishonest buyer before they receive confirmation, then that second recipient will lose both the payment and the goods.
2. Human dishonesty – pool organizers taking unfair share slices: Because bitcoin mining is best achieved through pooling (joining a group of thousands of other miners), the organizers of each pool get the privilege of choosing how to divide up any bitcoins that are discovered. Bitcoin mining pool organizers can dishonestly take more bitcoin mining shares for themselves.
3). Human mismanagement – online exchanges: With Mt. Gox being the biggest example, the people running unregulated online exchanges that trade cash for bitcoins can be dishonest or incompetent. This is the same as Fannie Mae and Freddie Mac investment banks going under because of human dishonesty and incompetence. The only difference is that conventional banking losses are partially insured for the bank users, while bitcoin exchanges have no insurance coverage for users.
Four Reasons Why Bitcoins Are Such a Big Deal
There is a lot of controversy around bitcoins. These are the top reasons why:
1. Bitcoins are not created by any central bank, nor regulated by any government. Accordingly, there are no banks logging your money movement, and government tax agencies and police cannot track your money. This is bound to change eventually, as unregulated money is a real threat to government control, taxation, and policing.
Indeed, bitcoins have become a tool for contraband trade and money laundering, precisely because of the lack of government oversight. The value of bitcoins skyrocketed in the past because wealthy criminals were purchasing bitcoins in large volumes. Because there is no regulation, however, you can lose out immensely as a miner or investor.
2. Bitcoins completely bypass banks. Bitcoins are transferred via a peer-to-peer network between individuals, with no middleman bank to take a slice.
Bitcoin wallets cannot be seized or frozen or audited by banks and law enforcement. Bitcoin wallets cannot have spending and withdrawal limits imposed on them. For all intents: nobody but the owner of the bitcoin wallet decides how their wealth will be managed.
This is really threatening to banks, as you might guess.
3. Bitcoins are changing how we store and spend our personal wealth. Since the advent of printed (and eventually virtual) money, the world has handed over the power of currency to a central mint and various banks. These banks print our virtual money, store our virtual money, move our virtual money, and charge us for their middleman services.
If banks need more currency, they simply print more or conjure more digits in their electronic ledgers. This system is easily abused and gamed by banks because paper money is essentially paper checks with a promise to have value, with no actual physical gold behind the scenes to back those promises.
Bitcoins are designed to put the control of personal wealth back into the hands of the individual. Instead of paper or virtual bank balances that promise to have value, Bitcoins are actual packages of complex data that have value in themselves.
4. Bitcoin transactions are irreversible. Conventional payment methods, like a credit card charge, bank draft, personal checks, or wire transfer, do have the benefit of being insured and reversible by the banks involved. In the case of bitcoins, every time bitcoins change hands and change wallets, the result is final. Simultaneously, there is no insurance protection of your bitcoin wallet: If you lose your wallet’s hard drive data or even your wallet password, remember: your wallet’s contents are gone forever.
What do the Billionaires say?
If something is “virtual,” does it really exist? When it comes to Bitcoin and other cryptocurrencies, this is an important question. You can buy and sell stocks, bonds, paper currencies and commodities like corn and wheat. They exist in the real world. You can physically deliver them, although they mostly are represented in electronic form. Although anyone can speculate on conventional investments like stocks and precious metals, it’s important to know what Bitcoin is not. Anyone is free to speculate on anything from land to football games. It’s human nature. Yet don’t confuse a cryptocurrency with something you can hold in your hand — like gold. And for every positive thing about Bitcoin, there seems to be negative things too. Here are what some of the world’s most insightful Millionaires and Billionaires have to say about Bitcoin, Blockchain and Cryptocurrencies.
