Jack Dorsey, the co-founder of social media platform Twitter, has announced he and US rapper-turned-businessman Jay-Z are investing a chunk of their own money into bitcoin development in Africa and India.
Mr Dorsey says they are putting a total of 500 bitcoin, worth around $23.6m (£17m), into the endowment fund called ₿trust.

The BBC's Catherine Byuaruhanga says that in Africa's commercial hubs like Lagos, Nairobi and Johannesburg, a growing number of people are finding that cryptocurrencies offer a cheaper solution to the expensive problem of transferring funds across borders.

A man has been arrested on suspicion of fraud and money laundering as part of a police probe into an international operation of fraudulent offers of drone light shows.
Nottinghamshire Police said the force made its first-ever seizure of cryptocurrency - a digital form of money traded online and exchanged in a similar way to traditional units of currency - worth about £78,000 after executing a warrant on 7 December.
A spokesman said police also secured a restraint order at Nottingham Crown Court to freeze £500,000 worth of assets while the investigation continues.
The 49-year-old man, who was arrested in Huthwaite, has been bailed.
