With Bitcoin, there is an open ledger called a block chain on which all transactions are recorded and monitored. Because of this, once a transaction is completed and recorded on the ledger, it cannot be changed. Transactions are available for verification by anyone and anytime. No one person or organization can manipulate it and therein lies [the biggest security feature]
Inflation is unlikely:
All traditional currency experiences inflation because of economies shift prices and governments continue to print more money. Bitcoin and other cryptocurrency do not experience this as much because there is a finite number of minable Bitcoins. It was programmed to have only about 21 million Bitcoins ever to be mined. Population growth is projected to stop when there are about 10 billion people which should be by 2050. The last Bitcoins will be mined around this period and no more will be introduced into the market.
Unlike physical money, large amounts of cryptocurrency can be transported easily without detection. It is possible to carry billions of dollars in Bitcoins in a memory drive on your person, though not advisable.
You control your money:
Since the users of digital currency are in control of their transactions, this helps in keeping it safe. Transactions are made independent of the identities of the parties making them. This protects users from identity theft.
Transactions cannot be traced:
This is both a pro and a con. The good thing about not being traceable is that there is no fear of any organization monitoring your source of funds. Freedom to buy and sell without the source of your funds being traced is a benefit in many parts of the world.
Several people don’t understand it and so are mistrustful of it.
Digital currencies like Bitcoin are not yet as widely known as they need to be. So, because not everyone knows it, and even fewer of them understand how it works, people tend to be mistrustful of digital currency, and the number of businesses which accept it as a form of payment are few. This is a limitation to people who want to use Bitcoins for their day to day transactions. Companies are also not to blame, however. Adding Bitcoin as a form of payment you accept would first of all require that you educate your staff about the concept.
Cannot be recovered if lost:
Unlike banks that have you covered in case of a security issue like a hacking or stolen credit card, Bitcoins are not retrievable if they’re lost. There are currently no mechanisms to recover lost Bitcoins. According to several people, the best way to store Bitcoins is on a drive that is not connected to the internet. This is because they are encrypted for security purposes. The encryption identifies the currency, but not the owner. Whoever has the codes owns the currency and this anonymity feature means stolen coins are lost – that is unless you can steal them back!
Transactions made with cryptocurrency cannot be traced:
This feature makes digital currency the perfect tool for criminal transactions. Just like drug dealers and other unscrupulous individuals use cash to avoid detection, transactions made with Bitcoin and others like it are virtually untraceable. This could be a reason for some governments to declare Bitcoin transactions illegal in their countries.
It is subject to market fluctuations:
When you want to invest in cryptocurrency, keep in mind that while it can be used to buy and sell, it is also a commodity like oil which is subject to changing market prices. When investing in cryptocurrency, it’s best to look at it as a long-term investment and not let momentary fluctuations in price make you think you’ve made a bad investment.
The Cons of Cryptocurrency are the main reasons why investors and hedge funds management are reluctant to invest their money in. (CNBC)
