halving makes bitcoin slower to be mined. however, if the price does not rise, then it might be bad for some people
It may be bad for some people
And good for some other people (who are shorting Bitcoin, for instance). And halving doesn't affect times between network confirmations. It may affect them if the hash rate drops abruptly because of it, but this impact will be temporary anyway. In a weak or so (on average) the difficulty will readjust, and everything will be back to normal. Bitcoin already accounts and allows for such things
you're right it might be beneficial for some type of traders
But overall bitcoin is bothered by halving, not boosted by it
Because, as it was said, transaction time goes up, fees go up, because of obviously miners close their btc mines and so on
Imo bitcoin has some sort of expiration date and this date is somewhere in this decade
