Our mindsets are still too much working in the old schemes.
That's the biggest problem that we humans have from forever... We have one guy inventing a wheel, and for the next hundreds of years, we still don't use it because we don't understand the full potential...
We are using 10% of our brains, and in some way, we are using a maximum of 10% of crypto potential at the moment... I believe that will change, but to see that happening, we have to work on that... To promote, to search for new use cases, to implement things, to educate, etc.
I have the feeling in our days we are pretty stuck in thinking patterns and we can't think out of the box. However, I believe that this is necessary for us to be able to find new, innovative ways to use the full potential of crypto.
