I totaly give up I was in their telegram group wanting to clear my doubts about how they are able to get power cables into their cave that sit in the middle of nowhere, asking how far is their power plant to their cave and how long are their power cables.
Then one of them from the team asked me if I am an electrical engineer, to which I answered no and said I was feel weird and suspicious , my exact word, didn't call them a scam or anything bad at them, simply sharing my concerns, to which I was kicked out of their telegram group.
In my opinion i think evryone need to watch out please share what you think
