I also wish to know before or when a projects start if they will make a real product, but mostly coins not have a real product, but maybe on future this will change and will appear some good projects.
a good project will certainly have a real product. some projects that have developed certainly have product development that is supported by the community. but what I know in the development of their products, most projects require a very long time.
I am keeping an eye on the roadmap dates and the first prototype of the robot should be ready by the end of May, so we'll see the truth reveal then
