From my experience, sending crypto from an exchange usually ends up being more expensive than transferring from a custodial wallet. Most exchanges charge network fees on top of their own service or withdrawal fees, which can fluctuate depending on blockchain congestion. For example, when transferring Bitcoin or Ethereum from major exchanges like Binance or Coinbase, the total cost can sometimes be noticeably higher compared to using a private wallet like Trust Wallet or MetaMask. Custodial wallets, on the other hand, typically only charge the network fee, and users often have more control over how much they want to spend by adjusting the gas price or transaction speed. However, exchanges can occasionally offer lower or even free internal transfers if both sender and receiver are on the same platform. So overall, custodial wallets tend to be more cost-effective for most transactions, but the actual difference depends on the network being used and the exchange’s specific fee structure.
