It's expected to reach that high but only based on speculation as we really don't know.
What I don't like is that $100k is even considered a conservative prediction which is high, I might believe it's conservative if bitcoin break it's ATH already and it's trading at $50k+ already, so my stance is I believe it will reach $100k but not in a short term period, and not a conservative prediction.

We gotta respect what people are saying now as they help to make this market more bullish, and what is expected actually is not the price itself, but people who are giving bullish predictions when the market is in bullish mode, the opposite would also happen if we are in bearish mode.
