By the way, can anyone help me understand this:
If the max supply is 5,000,000,000 BFG but the number of burned tokens (right now) is 1,299,640,665 BFG... Shouldn't that make max supply technically 3,700,359,335 BFG and decreasing as it constantly deflates?
That's how it should be.
......
dev actually controls all tokens.
That is true. They own all until it's distributed to all holders. You can see the token already minted if you check BFG on Tronscan. There are currently two but the latest is probably the official contract address for the merged BFG.
