The younger generations will take 40 or 50 years to reach that age yet. It's a lot of time, surpassing even my longest term predictions. It's impossible to say where crypto market will be at that point and if it will still exist by there. Meanwhile new technologies can be developed, political changes can happen, new governmental models be implemented, some countries can disappear, another ones can appear, Mars might be colonized, money could decrease its importance in people's lives, as the tendency is that life becomes more sustainable and less dependant on others as time passes... There are so many possibilities.

I just hope younger generations can thrive in different spheres, not only financially, and that the world reaches a higher level of average prosperity.
