The establishment of local offices by crypto firms in Nigeria, as directed by the Nigerian security and exchange commission (SEC), is a welcome development for several reasons:

1. Transparency and genuity: By having a physical presence in Nigeria, crypto firms demonstrate their commitment to transparency and genuity, which can help build trust with the government and regulators.
2. Customer support: Local offices can provide better customer support and services to Nigerian users, such as assistance with transactions, wallet management, and dispute resolution.
3. Regulatory compliance: By setting up offices in Nigeria, crypto firms can more easily comply with local regulations and guidelines, which can help to prevent illegal activities and ensure a safer trading environment.
4. Education and awareness: Local offices can also serve as educational centers, providing training and workshops on cryptocurrency and blockchain technology, which can help to increase adoption and understanding in Nigeria.
5. Internal issue resolution: As you mentioned, having a local presence can help to tackle internal Bitcoin issues, such as disputes and fraud, more efficiently and effective.

This development can help to promote the growth of the cryptocurrency industry in Nigeria, while also ensuring that it is done in a safe and responsible manner.
