This is a dumb idea. Don't send them money. Home Bitcoin mining is dead, killed by increasing difficulty.
It's not even a new dumb idea. Over 30 years ago, there was the
Frenette Friction Furnace, an electric motor driving a brake. This is just the Internet-enabled version of an old scam.
People always make this mistake. It's not the difficulty which hurts home miners, it's the difference in the cost of electricity and the lack of volume being ordered. When it comes to BTC mined per Gh/s, someone with 100 Ph/s will mine at the same rate as someone with 1 Th/s. If electricity costs were 0 and the miners all cost the same per Gh/s, the profits would also be the same.
