Understanding Cryptocurrency Exchange Fees and Tiers

Fees split into maker (adding liquidity, lower rates) and taker (removing it, higher), with most platforms tiering discounts by 30-day volume: $10K might cut 20%, $1M+ often zeros makers. Discounts via native tokens-like 25% on Binance with BNB or 100% on Crypto.com with CRO staking-add up fast for holders, but token price swings offset gains sometimes.

• Spot trades average 0.1%-0.5% total round trip.
• Fiat deposits: Free ACH/wire on Kraken over $10K, 1-4% cards elsewhere.
• Withdrawal fees match network gas: ~$1 BTC on Gemini, free stables on ONUS.
• Hidden spreads on "free" apps like Robinhood equal 1% effective cost.

Calculate total cost with tools like fee simulators; high volume users save 50-90% via VIP paths.
