Unfortunately, it is not easy to increase the price of Bitcoin to such an expensive price. $100k may require good news that can trigger investors and whales to buy more Bitcoin. The bias is that one year after the halving, the price of altcoins will rise and will most likely have a direct impact on the price of Bitcoin which will increase the price too.
It seems like you said that in reverse, mate, because as long as I know Bitcoin I have never seen any impact from altcoins after the halving and this impact could make Bitcoin increase its price 
. Because what I often see is the impact of an increase in the price of Bitcoin itself which can result in most altcoins experiencing an increase in the market even though some people call it an altseason. But in general you need to pay close attention so that you don't misunderstand why there are many altcoins increasing after the halving and now there are still many altcoins that are having difficulty increasing their prices because Bitcoin is still stagnant at $69K.
