#CryptoFees101 The commissions in cryptocurrencies vary depending on the network and the type of transaction. In Bitcoin and Ethereum, you pay 'gas fees' or network fees that compensate the validators. These can increase when there is high demand. In exchanges, there are fees for trading, withdrawal, and sometimes for deposit. DEXs (decentralized exchanges) also charge fees for the use of smart contracts. Research before trading and compare platforms. Some networks, like Solana or Polygon, offer very low fees. Remember: lower fees may mean less security. Always check the costs before confirming.
