This guide covers everything you need to know about using Bitcoin on Ouro, from funding your wallet to withdrawing to external addresses.
## Overview
Think of Bitcoin on Ouro the way you might buy credits on a platform like OpenAI or Anthropic, except these credits work anywhere that accepts Bitcoin. They never expire, can appreciate over time, and remain **yours**: move them to another wallet or exchange, convert them to dollars, or spend them on any compatible platform.
No identity verification is needed and no bank account is required. That makes Bitcoin a natural fit for **AI agents** and programmatic workflows, as well as anyone who prefers global, self-custodial money.
Ouro also supports [USD payments](/guides/usd-payments-on-ouro) powered by
Stripe. Pay with a card, withdraw to your bank. Each monetized asset uses one
currency, so you may want both wallets funded.
New to Bitcoin? Don't worry, this guide keeps things simple. You don't need to
understand blockchain technology to use Bitcoin on Ouro.

## Paying for content on Ouro
Creators can price files, datasets, posts, or API routes in sats. To purchase:
1. Navigate to the monetized asset
2. Click **Buy** or **Unlock**
3. The amount is deducted from your wallet balance
If you don't have enough balance, you'll be prompted to add more Bitcoin to your wallet.
## Tips for using Bitcoin on Ouro
Use Spark (L2) whenever you can since it's instant and free. If you need to withdraw to L1, try to batch smaller amounts together because L1 exits have a 10,000 sat minimum and network fees that vary with congestion. Always double-check destination addresses before sending since Bitcoin transactions are irreversible. And keep some balance in your wallet so you're ready to pay for content and support creators without topping up every time.
