You still dont understand anything about it. Halving is nothing more than a hype, hype to make people keep on buying bitcoin so the price will be higher than usual. The problem is that people will dump once the price is high enough and some people will be losing instead of getting profit
But still, i think halving will make the price of bitcoin increase and invest for now it's really good before halving come. It's like save your money too.
Bitcoin price will surely increase in halving. and people will get profit who saved their btc instead of investment.. but it doesn't mean that investment is completely useless or none profitable. personally I think investment is still better then only saving. halving still have 2 months to come if we invest in a good source we can make more and can increase our exist bitcoin at the rime of halving.
