When dealing with cryptocurrencies, whether you are buying, selling, sending, or receiving, you will encounter what is known as "fees." These fees are an essential part of how blockchain networks and exchanges operate. Understanding them will help you make informed decisions and avoid unpleasant surprises.

What are cryptocurrency fees?

Cryptocurrency fees are the costs incurred to complete transactions on blockchain networks or for services provided by cryptocurrency exchanges and wallets. These fees are not fixed; they can vary significantly based on several factors.

Why are there cryptocurrency fees?

There are several main reasons for cryptocurrency fees:

* Miner/validator rewards: In Proof of Work (PoW) networks like Bitcoin and Ethereum (before transitioning to Proof of Stake), users pay fees to miners who process transactions and secure the network. In Proof of Stake (PoS) networks, fees are paid to validators. * Preventing spam: Fees impose a small barrier to transactions, discouraging unnecessary or malicious transactions from flooding the network (spam attacks).
