The high expectations should be moderated so we can be able to appreciate the milestone growth bitcoin price has made. Commensurable with its age bitcoin price is doing great and only those who are not highly expectant setting their price scale at a great distance of 100k, 150k, 200k will care to appreciate the feat, some even predict as high as $1M in the next bull run and when the price doesn't go even close as expected they complain that the performance of bitcoin has been poor.
You have made a valid point, we should not expect from someone either its an entity's or asset's performance, we should not expect more so that in the end we have to disappoint. As you said many people will say BTC performed badly while their expectations are BTC will reach $150k or $1M (I mean really).
That's why knowledge matters as if they would have some knowledge of trading volume or market cap etc. in comparison to the real-world assets then they will expect less. For example few days back one of my UNI fellows asked me can BTC reach $1 Million I said yes but not in 40 years. Because to reach that point it needs a hell lot of market cap and investment in. I might be wrong here but it is what it is.
We can't expect it to reach the moon when there is no fuel in its engine. I hope you got my point here. However, my expectations for BTC are it can reach around $100k in the upcoming bull run and that's due to a number of factors.
