isn't there already some coins that would work well? ZETA
I think PotatoCoin will work better because it is specifically for agriculture in third world countries.
The people of third world countries even don't know btc.how about potatocoin?
We (the potatocoin development team, including myself) are going to travel to these places and help these people to start using PotatoCoin by creating secure methods to transact in the currency, primarily via cellphones, which are abundant in Africa.
