How Does Bitcoin Mining Work
Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. Its a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.
To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. This is how new coins are created and new transactions are added to the blockchain, says Okoro.
In the early days, it was possible for the average person to mine Bitcoin, but thats no longer the case. The Bitcoin code is written to make solving its puzzles more and more challenging over time, requiring more and more computing resources. Today, Bitcoin mining requires powerful computers and access to massive amounts of cheap electricity to be successful.
Bitcoin mining also pays less than it used to, making it even harder to recoup the rising computational and electrical costs. In 2009, when this technology first came out, every time you got a stamp, you got a much larger amount of Bitcoin than you do today, says Flori Marquez, co-founder of BlockFi, a crypto wealth management company. There are more and more transactions the amount you get paid for each stamp is less and less. By 2140, its estimated all Bitcoins will have entered circulation, meaning mining will release no new coins, and miners may instead have to rely on transaction fees.

How Many Bitcoins Are Currently In Circulation As Of 2020
As of 2020, there are just over 18 Million Bitcoins in existence. However, not all of them are actually usable. Among those 18 million, approximately 4 million bitcoins are lost whereas, around 1 million were stolen in various hacks and heists such as that of through Mt. Gox. That leaves us with 13 million bitcoins. Well hold on, do not forget the Whales! Whales are people who own a huge number of bitcoins stashed away in their wallets. Among these whales is the founder of Bitcoin, Satoshi Nakomoto, whose public address is home to about 1 million bitcoins which are roughly worth 10 billion US dollars.
As of today, about 5 million of bitcoin belong to around 1600 whales. Thats about 28% of the total circulation. After taking away all these unreachable coins, bitcoins left with a mere 44% of the total technical bitcoins in existence. Thats about 8 million in total.
Private And Public Keys
A bitcoin wallet contains a collection of key pairs, each consisting of a private key and a public key. The private key is a number, usually picked at random. From the private key, we use elliptic curve multiplication, a one-way cryptographic function, to generate a public key . From the public key , we use a one-way cryptographic hash function to generate a bitcoin address . In this section, we will start with generating the private key, look at the elliptic curve math that is used to turn that into a public key, and finally, generate a bitcoin address from the public key. The relationship between private key, public key, and bitcoin address is shown in Figure 4-1.
What Happens When All 21 Million Bitcoin Are Mined
A consequence of Bitcoin not reaching its planned cap is that it leaves open the possibility that the cryptocurrency’s network will remain functional for a long time after 2140. No bitcoins will be issued, but transaction blocks will be confirmed, and fees will become the primary source of revenue. Ultimately, Bitcoin’s network may function as a closed economy, in which transaction fees are assessed much like taxes are.
Can the rewards be in satoshis instead of actual bitcoin? Such a practice is unlikely and would require a change in the cryptocurrency’s protocol to take effect.
That said, it is difficult to predict the effects of Bitcoin almost reaching the overall supply promised by Satoshi Nakamoto. This is partly because Bitcoin’s ecosystem is still undeveloped. The cryptocurrency was originally conceptualized as a medium of exchange but it has found more popularity as a store of valuean investing assetinstead. It is possible that Bitcoin’s ecosystem and workings might undergo a transformation, similar to the one that has occured in its identity, between now and 2140.
Although there can only ever be a maximum of 21 million bitcoins, because people have lost their private keys or have died without leaving their private key instructions to anybody, the actual amount of available bitcoins in circulation could actually be millions less.

How To Prevent Losing Bitcoins
Take the extra step of securing your coins to avoid the frustration of losing your Bitcoins. Hardware wallets are the go-to when it comes to storing your funds. For an extra layer of security, keep an offline copy of your private key, but make sure youre the only one who has access to it.

Use In Illegal Transactions
The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and the media. Bitcoin gained early notoriety for its use on the Silk Road. The U.S. Senate held a hearing on virtual currencies in November 2013. The U.S. government claimed that bitcoin was used to facilitate payments related to Russian interference in the 2016 United States elections. However, a 2021 study led by former CIA director Michael Morell showed that broad generalizations about the use of bitcoin in illicit finance are significantly overstated and that blockchain analysis is an effective crime fighting and intelligence gathering tool.
Several news outlets have asserted that the popularity of bitcoins hinges on the ability to use them to purchase illegal goods. Nobel-prize winning economist Joseph Stiglitz says that bitcoin’s anonymity encourages money laundering and other crimes.

Other Important Statistics About Bitcoin Mining
The next important question in the mind of beginners is how many Bitcoins are mined per day. The closest answer for the same would be 900 Bitcoins. On the other hand, people are also frequently worried about questions like how many Bitcoins are lost. As a matter of fact, there is no specific way to find out the number of list of Bitcoins. It is difficult to separate a wallet that contains Bitcoin of long-term holders or a wallet containing lost Bitcoin. Therefore, it is quite difficult to find out the number of Bitcoins lost.
However, it is also important to take note of another crucial detail while finding out the number of lost Bitcoins. The 1 million Bitcoins mined by Satoshi Nakamoto, founder of Bitcoin, are actually an example of lost Bitcoins. The 1 million Bitcoins have not shown any movement since the last decade. Furthermore, there are also many other instances of trivial losses in a number of Bitcoins due to people throwing away their hard drives. So, it is quite difficult to get a clear estimate for how many Bitcoins are lost as all the stories of Bitcoin loss never make it to mainstream news.

Man Hacks His Bitcoin Vault
Former Wired editor Mark Frauenfelder wrote his password on an orange piece of paper in January 2017. In March, he and his wife jetted off to Tokyo for vacation. A month after returning from vacation, he noticed his orange slip was nowhere to be found. The house cleaner he hired while on vacation had apparently thrown away the piece of paper.
Unperturbed, he typed in the password from memory and received this message: Wrong PIN entered.
After three more fruitless tries, a countdown timer appeared on the screen, which made him wait a few seconds before he could try another PIN.
However, the delay doubled every time the wrong PIN was entered. From April to August, Frauenfelder tried hacking into his vault, to no avail.
One day, he received an email from the vault’s manufacturer explaining that the security was being updated. Per the email, there was a security vulnerability within the vault system that needed fixing. Frauenfelder reached out to a bitcoin expert who put him in contact with a 15-year-old coding whiz who could give him video instructions on how to exploit the vulnerability and hack the vault.
After agreeing to pay the teenager the equivalent of $3,700 in bitcoin, he received instructions that would hack his computer and show him the password.
“Following Saleem’s instructions, I copied a string of text,” he writes for Wired. “The PIN appeared instantly. Months of soul-crushing anxiety fell away like big clods of mud that had been clinging to my shoulders.”

Why Do These Limits Exist Anyway
You might find yourself wondering why Satoshi Nakomoto thought it would be good to limit the supply of Bitcoins. The concept behind this is to establish an automatically adjusted balance of supply and demand. The concept of Bitcoin emerged as a strong opposition or more so a remedial structure of transactions to the centralized banking system. One major flaw of the conventional banking system is the ability of the bank to curb or dilute the supply of money in the market, therefore, controlling the purchasing power, inflation and economic conditions along with it.
Bitcoin, on the other hand, aimed to establish a decentralized form of a network where no entity could influence in of itself the supply of the bitcoins, therefore, creating an automatically adjusting supply of bitcoins through capped supply and diminishing rewards.
So, to put things into perspective, Satoshi Nakomoto definitely did put in great thought into selecting the right timeframes, declining the mining rate and choosing to put a finite limit on the supply for Bitcoin. Now you may ask, the code is open-source, someone can just tweak that limit. Well, its not that easy. You can change the supply but if the majority of the nodes do not accept the change, it will result in hard fork, leading to some or most of the nodes choosing to stay with the original chain and the new forked chain ultimately dying out due to lack of interest.
Should You Buy Bitcoin
In general, many financial experts support their clients desire to buy cryptocurrency, but they dont recommend it unless clients express interest. The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesnt do well, and then all of a sudden they cant send their kids to college, says Ian Harvey, a certified financial planner in New York City. Then it wasnt worth the risk.
The speculative nature of cryptocurrency leads some planners to recommend it for clients side investments. Some call it a Vegas account, says Scott Hammel, a CFP in Dallas. Lets keep this away from our real long-term perspective, make sure it doesnt become too large a portion of your portfolio.
In a very real sense, Bitcoin is like a single stock, and advisors wouldnt recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if youre passionate about it. If it was one stock, you would never allocate any significant portion of your portfolio to it, Hammel says.

Reasons To Trace A Bitcoin Address
Financial institutions and government agencies like law enforcement and intelligence comprise a large bulk of those interested in pursuing Bitcoin address owners. Because of its anonymous nature, Bitcoin attracts criminals attempting to hide their trail.
The tactics described above help these agencies to:
- Prevent money laundering
- Prevent illegal drugs and firearms trades
- Issue subpoenas to identified criminals
- Insure taxes are paid on gains
- Avoiding scams
In fact, Bitcoin is super effective in catching criminals because it shows a whole pattern of criminal history as opposed to one instance. This article goes more in-depth on Bitcoin crime-fighting stories.
Regular civilians may instead want to track an address because of misplaced money. It can be easy to slip-up a number or letter in a drawn-out Bitcoin address. In the instance that the money was sent to a nonexistent address, its essentially lost in a blockchain void and there is unfortunately no way to get it back.
How Do You Get Bitcoins
There are four main ways to get Bitcoins: 1) Purchase on a cryptocurrency exchange like Coinbase or payment service like CashApp, 2) Sign up for an investment brokerage like Robinhood, 3) Find a cryptocurrency ATM or store, and 4) Use a crypto faucet to receive Bitcoins in exchange for completing tasks.
Once you have your cryptocurrency, you need to store it in a Bitcoin wallet. Every wallet comes with private keys and addresses used to access the wallet, which can be internet-based or hardware-based.
- A hot wallet is one that is connected to the internet, which makes it easy for investors to access their Bitcoin. However, it does pose a security risk, as you are susceptible to hacking and theft.
- A cold wallet is one that isnt connected to the internet, making it the safest way to store your currency. In this case, you print your private keys and addresses and store them somewhere, like a safe or safety deposit box. You can also store that information on a USB or hard drive.
Without your private keys and addresses, its impossible to access your Bitcoin. So, its imperative that you are careful about where you store this information.

Broken Or Lost Devices
Aside from keeping Bitcoin in online wallets, they can also be stored away from the net on hard drives. In fact, this is supposedly the safest way of storing your digital assets. However, if motherboards become fried or these devices break, then the owner loses access to the Bitcoins stored inside and the data kept in them can no longer be retrieved.
In other cases, owners lose or change devices such as laptops and/or mobile phones and forget about the coins stored inside them. One of the most popular lost Bitcoin incidents is James Howells in 2013.
After cleaning his house, he accidentally threw his hard drive into the trash along with 7,500 Bitcoins stored inside it. Howell tried to retrieve the hard drive in the local landfill, but the law prohibited him from doing so. Unfortunately, he never recovered his mined coins.
What Is A Bitcoin Wallet
A Bitcoin wallet is an equivalent of a bank account. It allows BTC users to receive Bitcoin and other cryptocurrencies, store them, and send them to others.
A wallet is basically your personal interface to the BTC network, similar to how an online bank account is an interface to the typical monetary system.
Bitcoin wallets contain secret codes known as private keys that allow users to spend their coins. When you get a private key from a trusted wallet such as Tezro, you need to safeguard it since losing it could mean losing all your assets!
