$ 100k is an unthinkable number at the moment. "experts" tend to underestimate and just want people to buy into bitcoin so they can sell it at a higher price. This is a common trick among whales right now and we should avoid it so that we don't get psychologically manipulated. For the current economy, it is highly likely that Bitcoin will drop to around $ 6k5 in the near future and then it will grow again. Don't put too much faith in halving when the world economy is not good, there will be no certainty and you should consider when investing.
Technically, it's possible for bitcoin to reach $100,000. After all of those all time highs that it made in the past, there's a larger chance that we may see $100k soon, not too quick but there's a chance that it can. Institutions are coming, halving was done, bitcoin is getting more scarce this time and as you understand the law of supply and demand. Those factors can trigger bitcoin to reach $100k. It's not a trick that the whales are saying, you need to understand too that bitcoin is always a speculative asset.
