Accounting & Invoicing

Strike delivers one of the cleanest Bitcoin buying experiences available, with trading fees starting around 0.99% for small purchases and dropping to 0.39% for larger volumes—consistently undercutting Cash App and PayPal on both trading costs and transfer fees. The app leans heavily on the Lightning Network, enabling near-instant payments with minimal fees, which makes it genuinely useful for everyday transactions rather than just buy-and-hold. Free ACH deposits, straightforward recurring purchases for dollar-cost averaging, and the ability to convert part of your paycheck directly into bitcoin round out a feature set designed for practical daily use.

On the trust side, Strike operates as a fully-reserved custodian, explicitly stating that customer assets are held 1:1 rather than rehypothecated. The company maintains SOC 2 Type II compliance, adheres to global AML and data protection standards, and has pursued licensing in stricter jurisdictions including El Salvador's digital assets regime. For users who prefer self-custody, bitcoin can be withdrawn to personal wallets via on-chain or Lightning at any time, reducing ongoing counterparty exposure.
