The halving of bitcoin is indeed a dirty little trick hiding in the source code.
The bitcoin white paper misleads:
"The steady addition of a constant of amount of new coins..."
Point being:
White paper does not mention halving !
Lets say even if it didn't mention it in the White Paper, how is it a "dirty little trick" and how does that change much of anything? There are quite a lot of changes that have been made to bitcoin and bitcoins blockchain code that have gone in to effect ever since Satoshi left the project entirely. Does that make all changes made a scam? I think you're grasping at straws here and seemingly just trying to find any way to bash bitcoin.
