This has always been an inevitable characteristics of all prices over the ATH (ie. anything bigger than $20k), people don't have any weird targets for their panic sells anymore so the increasing demand no longer has any kind of strong resistance against it so price keeps rising easier than before.

These 2 are contradictory. The "dump" in 2017 (which actually happened in final days and continued in 2018) will be repeated just as you said in first line, AFTER price reaches a similar bubble. Until then we will see many corrections with constant rising.
