Protection against fraud
Any business that accepts credit cards or PayPal knows the problem of payments that are later reversed. Chargeback fraud result in limited market reach and increased prices, which in turn penalizes customers. Bitcoin payments are irreversible and secure, meaning that the cost of fraud is no longer pushed onto the shoulders of the merchants.
No PCI compliance required
Accepting credit cards online typically requires extensive personal security checks and personal buyer information in order to comply with the PCI standard. Bitcoin still requires you to secure your wallet and your payment requests. However, you do not carry the costs and responsibilities that come with processing sensitive information from your customers like credit card numbers.
