Blockchain technology is currently used to find solutions to many problems in the world, but I do not think that this is a very accurate factor. The reason is that at the moment crypto coins should be used to perform financial transfers, while receiving a coffee in many places can not do with crypto coins so we use blockchain technology in this direction to achieve success in these projects, I think the effect rate increases. The project makes sense that everyone wants the world to be cleaner but when I look forward, I think this project will disappear.
