I personally want to see a sharp move down on BTC before halving

Market makers should do something to make people believe that this halving drop is coming as most of the traders are waiting for it. A dip before halving and then a quick recovery can set up a good trap for the people who want to see much lower prices.

if it goes up on/before halving and then comes back down down, this can be really bad and can take a deeper correction. As it will take out the current shorts and get the bulls liquidity.
