thinking bitcoin reaches $100k is something very realistic because as you said before, before the halving started the price of bitcoin had already reached $70k. However reality says otherwise because approaching the halving, Bitcoin prices tend to move down. Don't be discouraged, keep holding onto the Bitcoin you have because the opportunity to reach $100k is still wide open.
Bitcoin price must touch 100 as it is only a matter of time, as we are in the current halving it will touch together in time. The all-time high Bitcoin touched was 73.6, so the falling Bitcoin price has created an opportunity for investors to invest.
