Not the best analogy, IMHO

If the price of a stock or house or investment have been rising for two years, it's risen in cost to get into, and you might never see the gains people have seen in the past; I doubt you'll ever get a bitcoin for a dollar again!

But if job adverts for a new tech have been rising for two years, it doesn't cost any more to learn than on the day it was released. Maybe less, in fact, as there will be more tutorials and more experts to learn from.
