When you buy Bitcoin hen the price is 100k$ then how much will you sell it back to make profit because at that time the price of Bitcoin might not exceed 100k$ and if the price didn't not exceed that amount you will become a loser in the business so how does the vendors do at that time?
Or you buy at that time and thinking that it will go up to 200k$ but ironically, the price come below 100k$. What will be you faith/fate. Many companies stopped function last year because they accumulated a lot of Bitcoin when the price was high and they were thinking that the price would go up for them to sell them off and make their profit from there but instead the price of Bitcoin drastically come down very well. So the companies enter bankruptcy and folded. So exchange are trying to avoid such mistakes, so that they can run a long journey.
Will the price pass 100k$ next year 2024 for buys to make their gain?
That's somewhat true, but my friend I'm pretty sure that Bitcoin's price will far exceed the $100k price mark. Those people who invest in Bitcoin when it's price is at $100k will have to hold their investment if out of sudden the market crashes and the value of Bitcoin dumps. The good companies know the volatility of Bitcoin, and they only invest in Bitcoin the money that they don't need for more than 4 years.
The newbie investors who invest in Bitcoin when its price is at peak will have to know a fact that Bitcoin can dump anytime from its all time high, and they should study the market properly before investing their money into Bitcoin. However, I must say that the ones who believe in Bitcoin will never get panic if the value of Bitcoin drops to $50k after reaching $100k because they know that Bitcoin can again crosses that $100k price mark, and it can even reach $1 million or more in price after a decade or two.
