Bitcoin 'may not last that much longer,' academic warns

Because some bitcoin investors have become millionaires overnight, more and more people are intrigued by the possibility of striking it rich through investing in cryptocurrencies like Bitcoin. A cryptocurrency is a virtual medium of exchange that exists only electronically; it has no physical counterpart such as a coin or dollar bill, and no money has been staked to start it.
Cryptocurrencies are decentralized, meaning that there is no central authority like a bank or government to regulate them. The advantage of this is that there are no transaction fees, anyone can use it, and it makes transactions like sending money across national borders simpler. While transactions are tracked, the people making them remain anonymous.
This anonymity and lack of centralized regulation, however, means that tax evaders, criminals, and terrorists can also potentially use cryptocurrencies for nefarious purposes. Without physical money or a central authority, cryptocurrencies had to find a way to ensure that transactions were secure and that their tokens could not be spent more than once.
Bitcoin was born in when a mysterious person or persons named Satoshi Nakamoto whose true identity remains unknown , found a solution to these issues. Blockchain is a transparent database that is shared across a network with all transactions recorded in blocks linked together. Nodes —powerful computers connected to the other computers in the network—run the Bitcoin software and validate transactions and blocks. Each node has a copy of the entire blockchain with a history of every transaction that has been executed on it.
Nakamoto capped the number of bitcoins that could be created at 21 million. While there is speculation about the math theories that led to the choice of that number, no one really knows the reason behind it. As of this month, an estimated New bitcoins are released through mining , which is actually the process of validating and recording new transactions in the blockchain. The miner who achieves this first is rewarded with new bitcoin. Bitcoin mining farm.

This involves checking different variables, such as address, name, timestamp, making sure senders have enough value in their accounts and that they have not already spent it, etc. Miners then compete to be the first to have their validation accepted by solving a puzzle of sorts.
This random number must be less than or equal to the digit target set by the system, known as the target hash. This makes the network tamper-proof because changing one block would change all subsequent blocks.
The result is broadcast to the rest of the blockchain network and all nodes then update their copies of the blockchain. This validation process, or consensus mechanism, is known as proof of work. The winning miner receives newly minted bitcoin as well as transaction fees paid by the sender.
The higher the price of bitcoin, the more miners are competing, and the harder the puzzles get. The Bitcoin protocol aims to have blocks of transactions mined every ten minutes, so if there are more miners on the network with more computing power, the probability of finding the nonce in less than ten minutes increases. The system then makes the target hash more difficult to find by adding more zeroes to the front of it; the more zeros at the front of the target hash, the lower that number is, and the harder it is to generate a random number below it.
If there is less computing power operating, the system makes the puzzle easier by removing zeroes. The Bitcoin network adjusts the difficulty of mining about every two weeks to keep block production to ten minutes.
Every , blocks, the bitcoin reward for miners is halved. According to Investopedia , when bitcoin was first mined in , mining one block would earn 50 bitcoins. By November of , the reward was 6. This turned into a vicious cycle—an arms race—to have the most powerful computers, but then the more powerful hardware miners have, the more difficult it is to find the nonce.
The process of trying to come up with the right nonce that will generate the target hash is basically trial and error—in the manner of a thief trying random passwords to hack yours—and can take trillions of tries.
With hundreds of thousands or more computers churning out guesses, Bitcoin is thought to consume kwH per transaction. In addition, the computers consume additional energy because they generate heat and need to be kept cool. This is more than all of Argentina consumes, or more than the consumption of Google, Apple, Facebook and Microsoft combined. Bitcoin electricity consumption Photo: Elikrieg. And it is only getting worse because miners must continually increase their computing power to compete with other miners.
Moreover, because rewards are continually cut in half, to make mining financially worthwhile, miners have to process more transactions or reduce the amount of electricity they use. As a result, miners need to seek out the cheapest electricity and upgrade to faster, more energy-intensive computers. Between and March of , Bitcoin energy consumption increased almost fold.
According to Cambridge University, only 39 percent of this energy comes from renewable sources, and that is mostly from hydropower, which can have harmful impacts on ecosystems and biodiversity. In , China controlled over 65 percent of the global processing power that runs the Bitcoin network; miners took advantage of its cheap electricity from hydropower and dirty coal power plants.
As a result, many Chinese bitcoin miners are trying to move operations to other countries, like Kazakhstan, which relies mainly on fossil fuels for electricity, and the U. A number of U.
If the miners are unable to move, however, they are selling their equipment to other miners across the globe. One example of this is Greenidge Generation, a former coal power plant in Dresden, New York that converted to natural gas and began bitcoin mining. When it became one of the largest cryptocurrency mines in the U. Greenidge plans to double its mining capacity by July, then double it again by and wants to convert more power plants to mining by While Greenidge pledged to become carbon neutral in June through purchasing carbon offsets, the fact remains that without bitcoin mining, the plant would probably not be running at all.
Another estimated that bitcoin mining in China alone could generate million metric tons of CO2 by With more mining moving to the U. Power plants such as Greenidge also consume large amounts of water. Its large intake pipes also suck in and kill larvae, fish and other wildlife.

To be competitive, miners want the most efficient hardware, capable of processing the most computations per unit of energy. This specialized hardware becomes obsolete every 1. Since December, a new phenomenon in the art world has added to the environmental concerns about cryptocurrencies: NFTs. These are non-fungible tokens —digital files of photos, music, videos or other kinds of artwork stamped with unique strings of code.
People can view or copy NFTs, but there is only one unique NFT that belongs to the buyer and is stored on the blockchain and secured with the same energy-intensive proof of work process.
Ethereum, the second most popular cryptocurrency after Bitcoin, creates the NFTs. The average NFT generates pounds of carbon—the equivalent of driving miles in a gas-powered car—producing emissions 10 times higher than the average Ethereum transaction. An NFT. Image: id-iom. Because the entire Bitcoin network has invested millions of dollars in hardware and infrastructure, it would be difficult for it to transition to a more energy efficient system, especially since there is no central oversight body.
However, there are a number of projects seeking to reduce the carbon footprint of Bitcoin and cryptocurrency in general. The upshot was the creation of a new Bitcoin Mining Council to promote energy transparency.
The Crypto Climate Accord is another initiative, supported by 40 projects, with the goal of making blockchains run on percent renewable energy by and having the entire cryptocurrency industry achieve net zero emissions by It aims to decarbonize blockchains through using more energy efficient validation methods, pushing for proof of work systems to be situated in areas with excess renewable energy that can be tapped, and encouraging the purchase of certificates to support renewable energy generators, much like carbon offsets support green projects.
Ethereum is aiming to reduce its energy use by Rather it works like a lottery. To be considered, potential validators stake their Ethereum coins ETH ; the more they stake, the greater their chances of being selected randomly by the system to be the validator.
Ethereum 2. After a new block is accepted as accurate, validators will be rewarded with coins and keep the coins they staked. Image: Wangcoin. The system ensures security because if validators cheat or accept false transactions in the block, they lose their stake and are banned from the network. When the price of ETH rises, stakes become more valuable, and thus network security increases, but the energy demands remain constant.
Some worry, however, that proof of stake could give people with the most ETH more power, leading to a less decentralized system. So, for example, another proof of consensus mechanism is called proof of reputation : the more reputable you are, the more votes you have in validating things.
A few cryptocurrencies use proof of coverage that requires miners to provide a service—for example, hosting a router in their home to expand the network.
Some bitcoin mining is planned for West Texas where wind power is abundant. Because there is sometimes more wind power than transmission lines can handle, bitcoin mining situated near wind farms can use their excess energy.
Farrokhnia said that while these ideas are theoretically possible, they may not be pragmatic. Who in reality would make those investments given the volatility in price of bitcoin and the uncertainty about the future of it? He believes that cryptocurrencies cannot ignore environmental considerations if they want to gain wider adoption, and that newer and greener cryptocurrencies will eventually eclipse Bitcoin. Pretty sad. Thanks, I was looking for a reference to demonstrate the impact of crypto mining on global warming, and this is a great piece for that.

The 28 Most Sustainable Cryptocurrencies for 2022
The market is trying to recover from the recent crash as it suffered huge losses in a few days. The continuing bearishness has come as a huge blow to many investors who have lost their whole portfolio to these changes. There are chances that this new wave of bullishness will help recover the losses for those who can yet compete, but that might take time. As these new developments continue, there are few chances that the market will completely crash. The new developments in decentralized technology have taken firm roots, but the traditional system adopts the new change. Both systems need each other and might continue this in the future.
It’s Hard to Tell When the Crypto Bubble Will Burst, or If There Is One
Help us translate the latest version. Page last updated : January 26, This introductory paper was originally published in by Vitalik Buterin, the founder of Ethereum , before the project's launch in It's worth noting that Ethereum, like many community-driven, open-source software projects, has evolved since its initial inception. While several years old, we maintain this paper because it continues to serve as a useful reference and an accurate representation of Ethereum and its vision. To learn about the latest developments of Ethereum, and how changes to the protocol are made, we recommend this guide. Satoshi Nakamoto's development of Bitcoin in has often been hailed as a radical development in money and currency, being the first example of a digital asset which simultaneously has no backing or " intrinsic value " and no centralized issuer or controller. However, another, arguably more important, part of the Bitcoin experiment is the underlying blockchain technology as a tool of distributed consensus, and attention is rapidly starting to shift to this other aspect of Bitcoin. Commonly cited alternative applications of blockchain technology include using on-blockchain digital assets to represent custom currencies and financial instruments "colored coins" , the ownership of an underlying physical device "smart property" , non-fungible assets such as domain names "Namecoin" , as well as more complex applications involving having digital assets being directly controlled by a piece of code implementing arbitrary rules "smart contracts" or even blockchain-based " decentralized autonomous organizations " DAOs. What Ethereum intends to provide is a blockchain with a built-in fully fledged Turing-complete programming language that can be used to create "contracts" that can be used to encode arbitrary state transition functions, allowing users to create any of the systems described above, as well as many others that we have not yet imagined, simply by writing up the logic in a few lines of code.
India plans law that will prohibit ‘all private cryptocurrencies,’ with ‘certain exceptions’
You've probably heard a lot of talk about Bitcoin in recent years. Bitcoin is a type of cryptocurrency and there has been an increasing amount of interest around how this type of 'money' could become a bigger part of our day-to-day lives. Cryptocurrencies are now being used to purchase lots of different products and services, and some people are even buying big things like cars and houses with theirs! They're not widely used at the moment, but many believe the use of cryptocurrencies could one day become a common way to buy and sell things.

Put more simply, that means that anyone with a brokerage account will soon be able to buy and sell a bitcoin-backed financial product on the stock market. This comes after years of US financial regulators shying away from cryptocurrency , which is notoriously volatile. But now, it looks as though the government is ready to try new things. The debut was a big hit.
Crypto 101: Here are 10 cryptocurrency terms people use every day from blockchain to NFT
This is the third most expensive auction sale ever of a work by a living artist. That brought plenty of publicity—both to Beeple and to NFTs themselves. But high art is a strange world, one that for decades has run on hype, pumping prices, the convenience of transferring large sums of money through nominal purchases across borders, and an increasing detachment from any physical reality. That makes it a natural match for the world of blockchain. Nonfungible tokens are individually unique and can be used as an identifier for an individual object. An NFT is just a pointer, containing a website address, or maybe just a number.
EIB issues its first ever digital bond on a public blockchain
In the United States, cryptocurrencies have been the focus of much attention by both Federal and state governments. While there has been significant engagement by these agencies, little formal rulemaking has occurred. Many Federal agencies and policymakers have praised the technology as being an important part of the U. There have generally been two approaches to regulation at the state level.

The future of bitcoin is anyone's guess, but one academic has warned that the world's most popular cryptocurrency could fade out in the near future. At a. While there used to be just a few cryptocurrencies, today there are hundreds and some of them are more useful and more environmentally-friendly than bitcoin. Blockchain is the underlying technology behind most cryptocurrencies. It's essentially a digital ledger of virtual currency transactions which is distributed across a global network of computers.
What Happens to Bitcoin After All 21 Million Are Mined?
The winter session of the parliament starts November Lawmakers in India have for several quarters been discussing risks of cryptocurrency trading and trialing a central government-backed digital currency. An increasingly growing number of Indians, many of whom have never invested in the stock market or any other asset class, have started to trade cryptocurrencies in recent quarters, prompting concerns among some that they might end up losing their money. Local cryptocurrency exchanges have reported growing volumes of transactions and user bases this year and raised record capital from high-profile investors. Many lawmakers, in the meanwhile, have also expressed concerns about the nature of ads carried by cryptocurrency exchanges.
