Not exactly white hat, but these are 'services' I currently know of that are generating income for their owners, perhaps it may inspire some ideas to create something legitimate: * Running a bitcoin mining pool and accepting donations/small transaction fee * Running an actual bitcoin bank * Creating a meetup type app for bitcoin traders, would be very useful for Canadians and other non-US citizens where purchasing bitcoins is difficult * ForEx software for bitcoins. The fluctuations in price seem to be as random as real currency anyway, ForEx software and training is a very profitable industry. * Renting out or building bitcoin PC rigs with the latest GPU processing power * Bitcoin analytics, providing latest stats on potential bitcoin mining profit margins given the cost of electricity, video card hardware costs, and current trading price.
