Coinbase and Robinhood Listings

Don’t know if anyone noticed but Helium is on Coinbase’s latest list of projects that are being explored for being added onto their platform. However, having seen so many of these lists before and noticing that many of them never actually make it onto Coinbase, does anyone have any information on which projects are likely to be listed by Coinbase based on their long list of stringent criteria and requirements?

Any useful data someone can share on the the most important factors which have an influence on their listing of these projects would also be of great help.

And if anyone has any information on how Robinhood goes about this process as well, that would also be greatly welcomed.

Thanks guys!
