"From what I was told last night it appears block generation continues until block 200k so I guess what dev is saying is, He has miscalculated and underestimated the generation of coins resulting in his proposed max coins being reached before even halfway of the block generation...
I'm not sure if the 697,500,000 is a hardcoded max cap I can't read the code and the language barrier has been difficult.

If the coin goes passed the initial 697,500,000 I expect it will continue growing until block 200k where block generation apparently ends."

Just announced on Discord from one of the mods.
