Is the black diamond roadshow a pyramid scheme?

No, the roadshow is imported, from America. It is used to attract investment and financing and obtain policy support. Entrepreneurs introduce their projects through slides. The governments of some states and cities in the United States will also conduct city roadshows when attracting investment. For example, Apple's press conference, Jobs' product introduction, Xiaomi's product release, Lei Jun's stage display, and Luo Yonghao the hammer. It's just that roadshows are just emerging in China, and many people don't know much about them, but the important role of roadshows has been proved by foreign enterprises and governments.
