If all the different crypto projects were more coordinated and united this could be achieved soon or at least each month the whole crypto could have some positive progress.
You're going to need a more concrete example, both with the problem you want worked on with the amount of progress to be expected.
Bitcoin's most pressing problems at the moment, for example, are scalability and adoption. It's almost completely incompatible (either ideologically or technologically) with the scaling solutions other projects have taken (and vice versa), so I don't see how coordination could help on that end. It would be great if everyone could get together to promote crypto usage, but at the end of the day, everybody's already doing this, just each on their own time.
I suppose it would be nice to have some sort of united crypto front, but I honestly don't see how that's possible (properly, at least), or how it would even help.
If there's a will, there's way. All of us who uses cryptocurrency are hoping for a better world where cryptocurrency is adopted everywhere.
Maybe for now, it is really hard for most of the country to unite as one that uses cryptocurrency as a material in transactions. Until now, there are many countries who still don't understand how bitcoin works, so the adoption is also hanging and is slowly increasing. We, the people have the power to make it adopted not only by our friends, and families but also our Government, and when that happens, we can now freely use bitcoin in our everyday lives without any hindrance. Most probably the coins will also increase its price and can vary depends on the market where coins will have a large volume of users.
