My favorite idea for now is ModulTrade ICO. It's a trading platform for small companies all over the world. The idea of facilitation of global goods trading for small entities is brilliant! If for example I want to buy a giant wooden slab from a small shop in Bali and I want to do it being in US, there's so many additional costs to proceed payment that that slab turnes golden even if the initial price was resonable. Modultrade allows to contant this wood vendor directly and significantly reduce the cost.
