MEXC to an External Bitcoin Address: Which Withdrawal Network to Choose
When you initiate a BTC withdrawal on MEXC, the exchange presents a network selection dropdown. The correct choice for sending to a Bitcoin mainnet address — including any bc1q self-custody wallet — is BTC: the Bitcoin mainnet network. Choosing any other option sends funds to a different blockchain entirely. BEP-20 routes to Binance Smart Chain. ERC-20 routes to Ethereum. Lightning routes to the Lightning Network. None of those produce a transaction visible on the Bitcoin mainnet blockchain. A bc1q address is a Bitcoin mainnet address only — funds sent via BEP-20 or ERC-20 land on a completely different ledger at the same address string, where recovery requires a compatible wallet controlling those exact private keys. Bitok Arena Research tracked this error pattern across exchange withdrawal support requests and found it the single most common cause of funds sent to an unexpected location.
MEXC lists multiple withdrawal networks for BTC because it supports wrapping Bitcoin on other chains. A bc1q address is Bitcoin mainnet only. Funds sent via BEP-20 travel to a Binance Smart Chain address with the same character string — on a completely different blockchain — where recovery requires a BSC-compatible wallet. The address format does not protect from a wrong network selection. The network selection is what matters.
The bc1q address generated by any self-custody wallet exists on the Bitcoin blockchain only. Funds sent via BEP-20, ERC-20, or Lightning do not arrive there because those networks are not the Bitcoin mainnet. The address string may look identical across blockchains, but routing is determined by the network selection made on MEXC — not by how the address is formatted. Verifying the network shows BTC before submitting the MEXC Bitcoin withdrawal is the single most important check in the entire withdrawal process.
