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 !
But, but, but.... it has happened even before so why complain? You just have to embrace it as it's a feature that has been mentioned by the creator himself. I get that maybe you're looking and pointing at it with the POS = proof of scam and maybe you're not literally pointing it out to Bitcoin but with some other projects that has that POS algo.

Anyway, it's not a dirty trick and if the miners complains about it, they should have done it long time ago but no, maybe a few of you but not in general that most of the miners doesn't like it but they're already aware of it.
