I've seen the Bitcoin halving event last 2020 and I'm pretty sure most here also experienced the the 2016 and even the 2012. What I saw at that time is that, Bitcoin's price remained stagnant after the event. There's no immediate effect of it towards the price of Bitcoin. They're impatient? It's not your fault anymore if they're impatient. Tell to them not to invest anymore. Investing is a game of patience. Those who are patient enough to wait are the ones that will earn the most profit here. If they're impatient then tell to them not to invest anymore and just use their money in other things.
This is also one of the reasons why I'm hesitant to share anything related to cryptocurrency to other people.
