Bitcoin's exchange price cannot be predicted.
If bitcoin ETF is approved or not, the price will certainly get to $100000 in either this year or next year.
However bitcoin's value can be appreciated and will never change. Bitcoin is valuable for various reasons (PoW, limited supply, max supply cap etc).
Which is the reason we are certain that bitcoin will get to all-time-high and also get to $100000. Bitcoin price is not like fiat that will devalue but its price will increase after a long time. Bitcoin price is not easy to predict in short term, but in long term, it is very predictable and not disappointing.
