I agree with you, in fact, Bitcoin is a currency of such a nature that the more you wait to invest, the more you will fall behind. Every moment is very important to start investing in Bitcoin, invest first if you have money, the more you think about the value, the more confused you will be, because the value is never constant. The time and opportunity that is lost once, never comes back later. So never delay in starting investment, delay means losing time and opportunity. A skilled investor knows the true nature of Bitcoin, that is why a real investor never delays in investing. Whenever he has money to invest, he invests, and they are never afraid of instability, because instability is an opportunity for them. Because they are very sure and optimistic about the future of Bitcoin.
If someone doesn't have a clue about what is bitcoin then forcing them to buy can be a bad idea, what if the price crashed once they bought and you are the one who they will blame you. So guiding them when they realize bitcoin is their path is good but when someone still haven't made up their mind can take their time. Better late than never cause if they do it for wrong reason and faced the loss they might exit the market and will never think about coming back.
So this isn't entirely about the price, it's actually the cause that should drive them to invest, a person who truly understand bitcoin will not be shaken by the volatility so the short bumps and dumps will not likely to alter their strategy if DCAing or whatever they want to practice.
If you want to tell someone about Bitcoin investment, first tell them the risks. Because there are many people who, if they tell someone a thing, only talk positively about it, they do not tell the negative aspects of that thing, but this matter becomes a problem in the future. In the same way, to tell a new person about Bitcoin investment, you must present the all kind of risks of Bitcoin, and tell the truth, because Bitcoin is never risk-free. And also, forcing someone to invest without explaining Bitcoin well is only risky and in the future when Bitcoin dumps due to volatility, he will come to you and blame you for his losses.
So, do not force, you tell him about Bitcoin, and present him with the long-term potential profit potential of Bitcoin, as well as the risks. And then let him make the investment decision alone, remember that your responsibility is only to explain everything about Bitcoin to him and introduce him to the best Bitcoin investment strategy (DCA), and the rest of the investment decision will depend entirely on him. Overall, it is better to guide them properly rather than pressuring someone to buy Bitcoin, so that they can make their own decisions and be confident in investing.
