The price of bitcoin can experience price drop at 40k and it will be under probabilities for the price to crash to the extent of going beyond 30k and 20k, if such happens many people will be disappointed at bitcoin investment and investors will not allow such thing to happen, because if bitcoin mistake fall drastically many people will say that bitcoin is a scam and that will damage the images of bitcoin, so from my understanding of bitcoin and it's values I don't think bitcoin the price will drop more than 50k, because since we experienced 70k in price and the price keep on fluctuating it never pass 50k below in price.
You keep saying the price is falling and falling again, isn't it a big enough step to buy aggressively if the bitcoin price drops. If you are in the long-term Bitcoin accumulation stage, then the opportunity when the price drops is certainly an opportunity that you should use to buy BTC. Why do you firmly say that there are many people who are disappointed when the situation changes suddenly. I think ideally you should be more professional about what you should take advantage of when the decline occurs.
Now talking about $100k or Btc reaching $100k. Would you be satisfied if that was achieved, if yes then you are not a long-term holder, but it's up to you how you respond to it, what is clear is that BTC has a limited supply, even BTC could reach $200k someday. Patience is the key and while you are in the Btc accumulation stage, take advantage of the opportunity to buy dips and hold.
