The demo version that was promised in Barcelona has already been presented? Or not yet? This link
You are right. The demo version of the platform was showned only at a conference in Barcelona. But the platform has not yet been presented to investors and the video from Barcelona can not see for now.
I think the team is very busy with negotiations with large investors and partners, but soon we will see the results in Barcelona. After that, maybe I'll buy more tokens for me .
We already saw the results last week. But maybe this was the result of past agreements. It's hard for me to judge. Investors will not tell every person when they will contribute capital.
