Decentralization or Centralization I can not mention both as advantages or disadvantages. I prefer these two aspects to be referred to as the nature of currency. We cannot say that Decentralization is better than Centralization or vice versa. Because humans basically have their own preferences as currency users.

The advantages of cryptocurrencies over fiat are as follows

- Limited supply
- Transparent
- Full online
- Low cost
- Unlimited transactions between countries
- And much more
