Let's say a person drops a few million bucks and now has 51% of the network hashing power,
From what I understand, it would take
way more than a few million bucks to have more than 50% of the network hashing power.
Not that I would, but I was bored and calculated it out using existing tech, cost of space, servers, etc. And, I could do it for ~1.28mil per TH..... That's just cost, and has 0 to do with the value of that space, hardware, etc if used for something else. It simply is to state it CAN be done at that price and not how feasible it is or isn't...
