Bull Bitcoin
Non-custodial Bitcoin-only exchange and OTC desk. Instant self-custody withdrawals via on-chain, Lightning, or Liquid. No-KYC cash option via Canada Post. Canada, Europe, LatAm.
Bull Bitcoin is a Canadian Bitcoin-only exchange and OTC desk founded by cypherpunk Francis Pouliot. Its core principle is non-custody: when you buy Bitcoin, it is sent instantly to your own wallet — Bull Bitcoin never holds your funds. Supports withdrawals to any on-chain address, Lightning address, Lightning invoice, or Liquid BTC address. Payment methods include bank transfers, credit cards, and bill payments. A no-KYC cash option exists via Canada Post locations at a 2% fee plus a small processor fee — no ID, bank account, or credit check required. Standard online accounts require KYC per Canadian regulations. Serves Canada, Europe, Mexico, Costa Rica, Argentina, and Colombia, with more regions planned. The mobile app (BULL Wallet) is open source on GitHub (SatoshiPortal/bullbitcoin-mobile). Includes an OTC desk for large transactions. Bitcoin-only, always — the company has never offered altcoins.
