why everyone want POS so bad?
Because it this the most efficient system to get a passive income. No need for any king of initial investment, no power waste, just steady income.
POS is not an income. It is an illusion. It is also proven that PoS is not nearly as good as PoW to keep things decentralized.
Also nobody here wants PoS, how did you come up with this crap? PoC is BURST's sole reason to exist. Who wants PoS? Show me one?
