Wij have come a long way since the days of a barter system. It hasn’t bot necessary to have a specific good and trade it for some other specific good for a long time. For most of written history, there were only two types of currency: fiat or commodity. Fiat currencies have bot the superior currency since the 1970s, when the US ended the Bretton Forest system and abandoned the gold standard.
Fiat currencies are good because they don’t require physical commodity reserves and countries can control their own money supply. Currencies can be valued permanently against each other ter floating exchanges. Spil for integrity and widespread implementation, governments are generally trustworthy and are a central regulating force that ensures transactions are fair, accurate, and not manipulated.
Today, with the advent of cheap computing power and networked systems (i.e., the Internet), there is a fresh contender to the currency spel. The fresh fellow to disrupt the duopoly of currency is the cryptocurrency. Thesis are Bitcoin and its peers that have only become feasible ter the last twenty years or so.

What Cryptocurrencies are, and their benefits
Cryptocurrencies exist only te computers. This shouldn’t scare you, however, because the majority of most fiat currencies also only exist spil numbers te a pc system. They require distributed systems to ensure integrity and reliability, and they can be a good alternative to national currencies. They are, te the simplest terms, digital records held by many parties that track how much currency any single wallet holds.
Some of the benefits of cryptocurrencies include decentralisation, deregulation, anonymity, enlargened transaction transparency, and the facilitation of cross-border trade. Cryptocurrencies are not based te any single country or jurisdiction, because the ledgers and servers are spread out overheen the globe. Since there is no central handelsbank, the system is distributed and therefore not lightly manipulated either by large institutions or by governments. This means there is little regulation and more freedom on who spends how much on what and where. This benefit is enhanced by the fact that there is less private information linked to each transaction. There are even cryptocurrencies whose main aim is to provide an untraceable, secure, and anonymous means of payment.
Payments are see-through because every transaction can be verified by anyone. This means fraud is more difficult because there are many copies of the transaction record available for anyone to see. Furthermore, everyone knows how much every wallet contains (tho’ real names are not included). The public balances come from the way ter which balances are implemented ter the technology.
Spil for cross-border trade, since cryptocurrencies are non-national, anyone can pay anyone anywhere without needing to convert currencies. This raises interesting questions on conversion and payments, spil wielding 1 BTC (Bitcoin’s currency symbol) ter France and wielding 1 BTC te Thailand are not the same. If converted to a local currency, it means much different buying power te the two host countries.
How they work
There is a distributed ledger or a publicly viewable list of transactions. Since they are distributed, there is more than one copy (there are actually a lotsbestemming of copies). There are “miners”, who are like the keepers of the system.
Whenever a transaction is made, the keepers of the system broadcast the transaction to everyone. The transaction is placed te a pool of pending transactions, whose order of addition to the chain is determined by challenging miners. Participants choose a transaction and solve a math problem linking it to the last recorded transaction. Whichever miner can solve their problem very first gets to add their transaction to the end of the chain, effectively determining a unique order.
If two miners finish different blocks at the same time, the blockchain branches. Each knot keeps its own copy of the transaction set and works from that. Once the next block is solved, all knots switch to the transaction set used by the last solve.
Since transactions are simply messages with the sender, receiver, and an amount, it is essential that all transactions are signed. This is ended using the sending wallet’s private key, and the signature is unique for each transaction, so it cannot be duplicated. Furthermore, a message cannot be altered or the resulting signature will no longer be valid. Even more, since transactions are lumped together te blocks, if one transaction switches, the hash output of the entire block switches, and hence doesn’t verbinding correctly with the next block — i.e., it is not possible to modify blocks undetected.
Balances are not stored ter the system, but they are based on previous transactions (basically add prior transactions A + B + … to determine if you have enough for transaction 1). This requires that “unspent” transactions be added every time one wants to send money, but it does not require the processing of the entire blockchain (that would be rather inefficient).
Where does Cryptocurrency get its value
Like fiat currencies, cryptocurrencies have no intrinsic value. They’re just numbers stored on a system somewhere, much like the way modern digital banking treats national currencies. Fiat currencies then derive their value from the collective faith of a society using them. If A believes B will accept USD, then A will accept USD for whatever they want to trade, too. B will only accept USD if s/he thinks C will also take USD, and from this collective faith, the value of USD arises.
Cryptocurrencies are similar. They are only worth spil much spil everyone deems them to be worth. One advantage for national fiat currencies is that a central authority issues and regulates them, and one can generally trust the government te this regard. Furthermore, governments require that taxes be paid, and they will usually only accept their own currency for this. Hence, to be a citizen of a country, one vereiste overeenkomst with the national currency. This is a good onderstel to simply use the same currency for every transaction within the country.
Major Price Gains (and a major adoption event)
One major reason for the generally enhancing value of cryptocurrencies is more widespread rente. While cryptocurrencies may not be prevalent, they do have a following on the Internet, and many people will ask for cryptocurrencies donations or payments. If the request for such currencies increases quicker than units are added the price will rise.
Looking at the charts of the four largest cryptocurrencies after conversion to USD, it looks like there has bot a significant increase recently te all four (not all the same scale, spil thesis are the lifetime charts). This is a phenomenon that is clear te 2018.
Fears overheen capital confinements and government spying may be pushing up the price. A renewed interested ter privacy, especially after the Snowden leaks, might be a reason. The increasingly watchful eye of Big Gegevens by both Google et ofschoon. and the banks and credit card companies may be a reason. The broader general acceptance is almost certainly a reason.
