The change is the amount. You are 100% right about what you said, however the psychology of people changed because of the price. When it is few thousand dollars then people do assume 2x is easier, so from 3k to 6k sounds easier, and if it is 5 tk 10k that is still easier, or even 9k to 18k could become relatively easy. However when you are at 40k, it is harder to reach to 80k, or at least that is how people assume which is not half wrong but not fully right neither.
And you cannot really blame people in crypto for thinking like this because every cycle has become smaller in the multiples. I was lucky to see BTC go from below 1000 to 20k, and this year so far it has only did 3x from 20k to 64k.
At the same time people keep looking at other alts still doing 100x and 1000x and the main difference is in price.
