Always great to read other perspectives and partially I agree with you. Crypto in its current state is not enough for mass adoption. There are very limited use cases that actually work. The use cases that do work have been those closely related to privacy and currency. I, for instance, still foresee a world in which a currency not controlled by one specific party (like USD, Yuan, EUR) who decides on supply and inflation, will become the default unit of account and world reserve currency. Whether this will be Bitcoin, I don't know.
Next to that, investing into crypto will become more and more like investing in companies. Pure utility token sales will disappear for the most part and investors/speculators will demand rights or equity. Crypto simultaneously will spark the transition from a world in which the great risk/reward deals only being available to the 'accredited investors' to a world in which everybody can join (at their own risk of course).
This is not a next-year reality. It will take at least a decade to see serious shifts. The financial status quo has too much to lose and will do everything in its power to slow down this evolution.
I agree that if their wil be a big impact by crypto currency that it will take at least a decade. And in the coming years some really improved crypto currency need to be launched.
I'm not sure if it will ever become the same as investing in companies. Because it just ain't a share. The crypto coin does not generate any profit, while each company does generate a profit (or loss).
And if crypto should be the same as fiat, then I will also air that it just works differently.
In the end only time can learn us if either one of us will be right. Most likely something totally different will happen 😀
