Soo after seeing the messages in their Discord group, one guy exposed them pretty good...
This is one big bad ass scam.. Zmining is using the same whitepaper as Whalesburg project is..
How to check? Just copy/paste a paragraph from Zminings whitepaper, and paste it in Google.. You will see Whalesburg whitepaper pop up..
don't believe? Check the screenshots below, as posted in their group.
Now tell us, who is the scam here?

BUSTED
Sure, our projects look the same - we have the same idea. But we are developing a much cheaper alliterative to Whalesburg that will allow us to charge our users less. So, devs, OP..
anyone like to comment against these allegations ??
Their discord seems to be dead.. flat-lined.. No communication in from the devs/team What so ever... Only investors that have questions that are not being answered..
I would like to give them the benefit of the doubt... but without any proper communication its hard to.
IF theres still any life on the other side.. Reply.

We will try to communicate more, we have just been a little bit busy with the development. Updates coming soon!This is a scam, banned me from Discord when I was asking too much about dev team and updates.
Sorry to hear that, it might've been a misunderstanding. What is your nickname on Discord please?Contact me on Discord please. @Walter
