I suggest we wait till Bill Gates shows a proof of his support in the US, where he lives. There's something strange in seeing the man enthusiastic towards BTC in Kenya, while he still have to show the smallest sign of support for BTC in his home country...
Do you want him to funds bitcoin development in US too? There are many people that support bitcoin in US, and bitcoin have began to be a mainstream thing there. Prefer Africa as a place to develop bitcoin than US is a better thing for him and his foundation.
