1. Decentralization vs. centralization:
Banking system, a majority of digital currencies are regulated by regulatory bodies like the Federal Reserve or other designated government parastatals. This means that transactions are constantly monitored, and their value determined by these regulatory bodies.
On the other hand, cryptocurrencies are fully decentralized. This means that no institution is set aside to regulate them. The rules are set by its community. As a result, the viability of a cryptocurrency is highly dependent on the strength its community can garner.
wrong.
first of all this is not a difference between the two categories.
secondly being a cryptocurrency doesn't mean it is also "decentralized". as an example you can take a look at so many
centralized altcoins. they also are cryptocurrencies but they are fully centralized. examples are XRP, USDT, ETH, ...
2. Privacy:
Privacy in this sense refers to the ability to conceal the information of the account owner.
With digital currencies, this is practically impossible. To open a digital account, you need to upload your photo and fill in your personal details, to make use of services like PayPal, you have to fill in your information like name and address. Hence, you can easily be tracked.
On the other hand, you don’t necessarily need to disclose any of your personal information when opening a wallet for cryptocurrency trading. In fact, coins like Dash are available to provide full anonymity, and this is one of the reasons why cryptocurrencies were widely used on the dark web.
not necessarily.
again a cryptocurrency may not even provide you with any kind of privacy. it just happens that bitcoin and a lot of the altcoins do it. otherwise there can be coins that don't give you any kind of privacy.
3. Transparency:
The framework of digital currencies only allows approved entities to get access to the transaction information. Information regarding transactions of which you’re not directly connected is withheld from you.
On the other hand, cryptocurrency transactions are made available to the public domain. Even though the people behind the transactions are unknown, this way, you can personally monitor how much money is in the system.
i wouldn't say this is a difference either because you are generalizing again. for example in case of anon coins such as Monero, they offer enough obfuscation that makes it impossible to track, monitor,...
6. Transaction interference:
Since transactions are monitored by central authorities when using digital currency, they can easily flag transactions suspected to be suspicious or even freeze an account temporarily on the request of the owner. This makes transaction reversible.
On the other hand, once a transaction is completed with cryptocurrency, it is automatically added to the Blockchain and is forever irreversible.
this point depends on whether the coin has immutability or not. and again the centralization issue arises. for example in bitcoin when your transaction is included in a block, it will be practically irreversible because of the design and the fact that reversing it needs an attack and costs a lot.
but a centralized coin without immutability can easily reverse any coin they want, and even spend them.
basically i would say the main difference (if not the only one) is that cryptocurrency is a sub category of digital currencies that is based on cryptography and the blockchain technology.
