Well, in vain, I once was at such events, and you know, I witnessed how one project (I will not disclose the name, maintain confidentiality) for one evening received not only several investors, but also interest in further cooperation and development. I think it's worth the risk and invest in their speeches and presentations. So there will be a lot more sense.
You are absolutely right. I also know many examples when attending conferences, projects found new major investors and new business partners. Attending crypto conferences is a very important part of project development.
I hope that all is not lost! After all, the project is only at the stage of development , maybe the guys still decide at least to hold either an online presentation, or to begin with in their hometown. By the way, where are these guys from? Of course it would be cool to see guys at world-famous conferences!
