#CryptoFees101 is an expression or hashtag used to explain in a basic and didactic way how fees work in the world of cryptocurrencies. The "101" suggests that it is an introductory guide, like a basic class on the subject for those who are just starting.

Understanding Fees in Cryptocurrencies

1. What are fees in crypto?

Transaction fees are small amounts paid by users to move cryptocurrencies on a blockchain. These fees are rewards for validators/miners, who process and confirm transactions.

2. Why do these fees exist?

Security: They ensure that the network remains decentralized and protected.

Preventing spam: They prevent someone from congesting the network with thousands of useless transactions.

Compensation: Miners or validators receive these fees as an incentive to keep the network active.

3. Main examples

Blockchain Type of Fee Common Name

Bitcoin Fee per byte Mining fee

Ethereum Fee per gas (gas) Gas fee

Solana, Avalanche, Polygon etc. Network fee Network fee

Practical example: Sending Bitcoin costs a "fee" that depends on the size of the transaction and the congestion of the network. In Ethereum, the cost depends on how much "gas" your operation consumes.

4. Factors that affect the price of fees

Network congestion: The more full the blockchain, the higher the fee.

Type of transaction: Simple transactions (like sending a coin) cost less than complex interactions (like smart contracts).

Used blockchain: Some are known for low fees (e.g., Solana), while others have higher fees (e.g., Ethereum during peak times).

5. Important highlights

Fees can be fixed or vary according to supply and demand for space in blocks.

There are guides and websites that show in real-time the average fee prices by blockchain (Example: cryptofees.info {target="_blank"}).
