I feel Jake's pain!!! Due to lack of donations upon release of roadmap and whitepaper the new devs will now have to withdraw their support.
These devs had the right experience having worked on different global mobile money projects and the right interest and programming skills however they had not been involved in Crypto hence to pay them some minimum stipends in BTC and Pesa for the 2 month revival work. 4BTC and 1M Pesa was very reasonable for the roadmap highlighted. Other devs on this forum ask for hundreds of BTC.
Anyway wish you guys all the best as I don't see any need continuing in a project with no community support.
