they've mentioned about creating their own cryptocurrency and assured of 30% - 40% return monthly.
I don't know why even today, people tend to invest in this kind of scam. People are easily deceived and being scammed because they continue to do such thing as investing and having ROI monthly. There is no such thing as investing and having a guaranteed return without doing anything. Not only in crypto space, even in real world, people should realize it that earning money is not easy as that.
