Overview#For Cryptocurrency we refer to others that can keep up with Cryptocurrency
It’s fast#When you pay a cheque from another bank into your bank, the bank will often hold that money for several days, because it can’t trust that the funds are really available. Similarly, international wire transfers can take a relatively long time. Cryptocurrency transactions, however, are generally far faster.
Transactions can be instantaneous if they are “zero-confirmation” transactions, meaning that the merchant takes on the risk of accepting a transaction that hasn’t yet been confirmed by the Cryptocurrency blockchain. Or, they can take around 10 minutes if a merchant requires the transaction to be confirmed. That is far faster than any inter-bank transfer.
It’s cheap#What’s that you say? Your credit card transactions are instantaneous too? Well, that’s true. But your merchant (and possibly you) pay for that privilege. Some merchants will charge a fee for debit card transactions too, as they have to pay a ‘swipe fee’ for fulfilling them. Cryptocurrency transaction fees are minimal, or in some cases free.
Central governments can’t take it away#Remember what happened in Cyprus in March 2013? The Central Bank wanted to take back uninsured deposits larger than $100,000 to help recapitalize itself, causing huge unrest in the local population. It originally wanted to take a percentage of deposits below that figure, eating directly into family savings. That can’t happen with Cryptocurrency. Because the currency is decentralized, you own it. No central authority has control, and so a bank can’t take it away from you. For those who find their trust in the traditional banking system unravelling, that’s a big benefit.
There are no chargebacks#Once Cryptocurrencys have been sent, they’re gone. A person who has sent Cryptocurrencys cannot try to retrieve them without the recipient’s consent. This makes it difficult to commit the kind of fraud that we often see with credit cards, in which people make a purchase and then contact the credit card company to make a chargeback, effectively reversing the transaction.
People can’t steal your payment information from merchants#This is a big one. Most online purchases today are made via credit cards, but in the 1920s and ’30s, when the first precursors to credit cards appeared, the Internet hadn’t yet been conceived. Credit cards were never supposed to be used online and are insecure. Online forms require you to enter all your secret information (the credit card number, expiry date, and CSV number) into a web form. It’s hard to think of a less secure way to do online business. This is why credit card numbers keep being stolen.
Cryptocurrency transactions, however, don’t require you to give up any secret information. Instead, they use two keys: a public key, and a private one. Anyone can see the public key (which is actually your Cryptocurrency address), but your private key is secret. When you send a Cryptocurrency, you ‘sign’ the transaction by combining your public and private keys together, and applying a mathematical function to them. This creates a certificate that proves the transaction came from you. As long as you don’t do anything silly like publishing your private key for everyone to see, you’re safe.
It isn’t inflationary#The problem with regular fiat currency is that governments can print as much of it as they like, and they frequently do. If there are not enough US dollars to pay off the national debt, then the Federal Reserve can simply print more. If the economy is sputtering, then the government can take newly created money and inject it into the economy, via a much-publicised process known as quantitative easing. This causes the value of a currency to decrease.
If you suddenly double the number of dollars in circulation, then that means there are two dollars where before there was only one. Someone who had been selling a chocolate bar for a dollar will have to double the price to make it worth the same as it was before, because a dollar suddenly has only half its value. This is called inflation, and it causes the price of goods and services to increase. Inflation can be difficult to control, and can decrease people’s buying power. Cryptocurrency was designed to have a maximum number of coins. Only 21 million will ever be created under the original specification. This means that after that, the number of Cryptocurrencys won’t grow, so inflation won’t be a problem. In fact, deflation – where the price of goods and services falls – is more likely in the Cryptocurrency world.
