#CryptoFees101 as Fees in crypto are amounts paid to perform transactions on blockchains. They serve to incentivize validators or miners to process these operations. In networks like Ethereum, fees are called "gas" and vary with network demand. Faster blockchains, like Solana or Polygon, tend to have much lower fees. Additionally, exchanges (CEXs and DEXs) also charge trading, withdrawal, or deposit fees. Understanding these charges helps optimize your costs, especially when trading frequently. Some wallets and protocols allow manual adjustment of fees, balancing speed and price. Paying attention to this avoids surprises.
