#CryptoSecurity101 Understanding transaction costs is vital for profitable trading. #CryptoFees101 includes network fees (paid to miners or validators) and exchange fees (paid to the platform). Ethereum, for instance, can have high gas fees during congestion, which affects smaller transactions disproportionately. On centralized exchanges, fees vary depending on your trading volume and whether you're a maker or taker. I usually trade on platforms that offer fee rebates or lower fees for using native tokens like BNB or KCS. Monitoring fees helps optimize your entries and exits. It’s also worth checking if exchanges offer “zero-fee” promotions for certain pairs, which can boost your ROI over time.
