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?
Any reasonable person who buys a bitcoin for $100k will only sell it if there is a profit from it. How much exactly? This will depend on the objectives of the investor. I guess 50%-100% profit would look attractive. But this is not the limit, if hold for a long time.
The price for bitcoin in 2024 is unlikely to exceed $100k. This can happen a little later, after the halving, as it happened, with some time delay. In general, the probability is high, because during the last bullrun the mark of ~$70k was reached.
