💸 Crypto Fees 101: Understanding Blockchain Costs

🧾 1. Types of Crypto Fees

1.1 Network/Transaction Fees (Gas Fees)

Paid to miners/validators for processing transactions.

Varies by blockchain:

Ethereum (ETH): Gas fees can be high during congestion.

Bitcoin (BTC): Fees depend on network activity.

Solana, Avalanche, Polygon: Usually low fees.

Tip: Check gas prices before sending — use tools like Etherscan Gas Tracker.

1.2 Exchange Fees

Trading Fees: Charged by centralized exchanges (e.g., Binance, Coinbase) when buying/selling crypto.

Often a % of the trade (e.g., 0.1%–1%).

Lower fees for high-volume traders or those using native tokens (e.g., BNB on Binance).

Deposit/Withdrawal Fees:

Some exchanges charge to deposit/withdraw crypto or fiat.

Withdrawal fees vary by asset (e.g., BTC withdrawals often have higher fees than TRX).

1.3 Wallet Fees

Most non-custodial wallets (like MetaMask or Trust Wallet) don’t charge fees directly, but you still pay network fees.

Some wallets charge a markup or service fee when swapping tokens inside the app (e.g., 0.5–1%).

1.4 DeFi Fees

Using DeFi platforms (like Uniswap, Aave, or Curve) can involve:

Gas fees (especially on Ethereum).

Protocol fees (e.g., 0.3% on Uniswap trades).

Slippage — the price change during the transaction.
