#TradingMistakes101 A trending mistake in crypto trading on centralized (CEXs) and decentralized exchanges (DEXs) is neglecting fee structures, impacting profitability. On CEXs like Binance, users often overlook withdrawal fees ($1-$15 for Bitcoin) or hidden spreads, eroding gains. On DEXs like Uniswap, ignoring gas fees during high network congestion ($5-$50 per swap) leads to unexpected costs, especially for small trades. Another error is misunderstanding order types, like using market orders during volatility, causing slippage. Traders also fail to secure assets, risking hacks on CEXs or key mismanagement on DEXs. Researching fees, timing trades, and prioritizing security can mitigate these costly mistakes.
