How does cryptocurrency work
Hardware Wallet: een nadeel van een online blockchain wallet is het risico dat je BTC kan worden gestolen als deze wordt opgeslagen in een zogenaamde “hot wallet” die is verbonden met het internet. https://polaris-pos.com/why-do-we-need-cryptocurrency/ Een hardware wallet betekent dat je munten worden versleuteld en opgeslagen op een fysiek apparaat, offline en in koude opslag. Veel van deze producten ondersteunen ook andere cryptocurrencies, waaronder Ethereum.
Bitcoin runs on a decentralized, peer-to-peer network, making it possible for individuals to conduct transactions without intermediaries. Transactions are transparent and secure thanks to the underlying blockchain technology, which stores and verifies recorded transaction data. Miners validate transactions by solving complex mathematical problems with computational power. The first miner to find the solution receives a cryptocurrency reward, thus creating new bitcoins. Upon validation, the data is added to the existing blockchain, and it becomes a permanent record. Bitcoin provides an alternative way to transact that’s transparent and secure, redefining traditional finance.
Fifty bitcoin continued to enter circulation every block (created once every 10 minutes) until the first halving event took place in November 2012 (see below). Halvings refer to bitcoin’s issuance system, which was programmed into Bitcoin’s code by Satoshi Nakamoto. It essentially involves automatically halving the number of new BTC entering circulation every 210,000 blocks.
Being the trailblazer and the first to appear on the market, Bitcoin is the ‘OG’ cryptocurrency that created a truly global community capable of making transactions without needing to trust the legacy financial system.
What is cryptocurrency
In 1996, the National Security Agency published a paper entitled How to Make a Mint: The Cryptography of Anonymous Electronic Cash, describing a cryptocurrency system. The paper was first published in an MIT mailing list (October 1996) and later (April 1997) in The American Law Review.
A cryptocurrency wallet is a means of storing the public and private “keys” (address) or seed, which can be used to receive or spend the cryptocurrency. With the private key, it is possible to write in the public ledger, effectively spending the associated cryptocurrency. With the public key, it is possible for others to send currency to the wallet.
On 11 November 2022, FTX Trading Ltd., a cryptocurrency exchange, which also operated a crypto hedge fund, and had been valued at $18 billion, filed for bankruptcy. The financial impact of the collapse extended beyond the immediate FTX customer base, as reported, while, at a Reuters conference, financial industry executives said that “regulators must step in to protect crypto investors.” Technology analyst Avivah Litan commented on the cryptocurrency ecosystem that “everything…needs to improve dramatically in terms of user experience, controls, safety, customer service.”

China cryptocurrency
Brazil instated cryptocurrency regulation in June 2023, when it made the central bank the supervisor for crypto assets. The Cryptoassets Act sets rules for any company providing services linked to virtual assets, with a central aim of preventing scams related to cryptocurrency.
Despite the strict capital controls in place, Chinese authorities have always been wary of capital flight. The effectiveness of these capital controls is somewhat debatable, as some commentators argue that capital flight grew significantly between 2009 and 2018. Meanwhile, in 2017, the PBOC banned the operations of cryptocurrency exchanges within China. (The 2017 ban did not go so far as to forbid the ownership or mining of cryptocurrency, which the 2021 ban finally prohibits.) Although China did not cite capital flight as a reason for its cryptocurrency restrictions in 2017, Chinese authorities did place additional restrictions on overseas investments by Chinese companies that same year. In some ways, the 2017 restrictions on cryptocurrency exchanges in China can be seen as the harbinger of the subsequent tightening of outward investment of Chinese companies that year.
The collapse of FTX underlined the “urgent need for imposing rules which will better protect Europeans who have invested in these assets, and prevent the misuse of crypto industry for the purposes of money laundering and financing of terrorism,” said Elisabeth Svantesson, Finance Minister for Sweden, which holds the EU presidency.
Cryptocurrencies
How many cryptocurrencies are there? In short, there were over 9,000 as of 2023, although there were many more digital coins in the early months of 2022. Note, however, that a large portion of cryptocurrencies might not be that significant. There are other estimates of roughly 20,000 cryptocurrencies existing, but most of these are either inactive or discontinued. Due to how open the creation process of a cryptocurrency is, it is relatively easy to make one. Indeed, the top 20 cryptocurrencies make up nearly 90 percent of the total market.
Currently, the cryptocurrency market has been experiencing a period of volatility, with fluctuations in the value of major cryptocurrencies such as Bitcoin, Ethereum, and Dogecoin. The market has also seen a rise in the number of altcoins, or alternative cryptocurrencies, with unique features and use cases.Several growth factors are driving the growth of the cryptocurrency market, including increasing acceptance and adoption of cryptocurrencies by individuals and institutions, growing interest in decentralized finance (DeFi) platforms, and the potential for cryptocurrencies to serve as a hedge against inflation and political instability. Additionally, advancements in blockchain technology and the increasing use of cryptocurrencies for cross-border transactions are also contributing to market growth.The cryptocurrency market is expected to continue growing in the coming years. The increasing adoption of cryptocurrencies by businesses and individuals, along with the ongoing development of DeFi and other blockchain-based platforms, is likely to fuel this growth. However, the market is also likely to experience volatility and corrections, as is typical with any emerging and rapidly evolving market.
Crypto.com describes it completely revamped its methodology in July 2021 as opposed to its previous work from May 2020 – due to the acceleration of the crypto world. It remarks that it now uses on-chain data for Bitcoin and Ethereum, counting the number of on-chain deposit adresses found within the largest coin exchanges. That said, the source does openly state that its figures are “a proxy only and subjected to various limitations and caveats”.The numbers shown here from CJBS were collected by the source from “longitudinal account and user data of both small and larger service providers from publicly available sources such as press releases, news articles, company websites, and public forums. This dataset was combined with survey data from participating platforms and projects from 47 countries.”CJBS mentions the figures provided are the “lower-bound of the global cryptoasset unique user base” and adds the following information: “The analysis does not capture all accounts at service providers since no data was available for some major platforms (e.g. in China) or individuals who do not use service providers. Together, these would contribute to an underestimation of total users. On the other hand hand, there are no easy means to identify users with accounts at multiple service providers – a practice that would contribute to an overestimation. Overall, there are reasons to believe that the underestimation factors outweigh the overestimation factors, which suggest that the current figure is a conservative lower-bound estimate.”
Any private individual or company that knows how to write a program on a blockchain can technically create a cryptocurrency. That blockchain can be an existing one. Ethereum and Binance Smart Chain are popular blockchain platforms for such ends, including smart contracts within Decentralized Finance (DeFi). The ease of crypto creation allows some individuals to find solutions to real-world payment problems while others hope to make a quick profit. This explains why some crypto lack utility. Meme coins such as Dogecoin – named after a Japanese dog species – are an infamous example, with Dogecoin’s creator coming out and stating the coin started as a joke.
Based on 24 hour trading volume, stablecoin Tether outpaced Ethereum and Bitcoin in January 2024. This is somewhat similar to a market cap league table of more than 100 cryptocurrencies — including ones for DeFi, NFT and stablecoins. The two virtual coins were the only ones to reach over 100 billion U.S. dollars, with Ethereum following by around one half this amount. Does this mean that Bitcoin gets traded more than Ethereum? Not necessarily, as the daily transactions of Ethereum tend to be significantly higher than that of Bitcoin.
