First, I think polycub needs an audience outside the Hive Blockchain.
Most of the AMAs and Official announcements done on Cub /polycub are mostly on Hive, Discord, and the Facebook page of Leofinance. In as much as Twitter and Facebook are getting Polycub to other investors outside Hive, it is not yet enough.
The polygon network itself has a large number of followers both on Twitter, Discord, and other social media, projects on the polygon network get huge audiences when they organize AMA in the polygon community, either through Twitter space or live Telegram AMA. Their announcement of the project and the AMA gets the project out to not just investors but also exchanges on the polygon network that may want to list the project on their exchange.
Again, partnering with some of the popular projects on the polygon network is another great tool.
