David Haye has been one of my favorite YouTube sources on information since I started in crypto also. I think you made a good choice there and thanks for sharing this because I feel others could stand to benefit from his work also.

In terms of your question will Crypto divide humanity, I feel like it already has in many ways. There are those who avidly support it and those that do not, but the biggest constraint is the government crackdowns and the forceful prevention across the world in many countries against cryptocurrency when honestly you should be able to whatever you want with your money short of funding illegal activities or terrorist organizations. Personally I think Blockchain technology will become the future of technology and that the technology built on top of blockchains and will become part of everyday life whether people want it to or not, over time of course. So put me down on the side of humanity that will do whatever they can to continue to promote crypto and push for its continued success.

I will say that I personally believe that crypto has the greatest impacts or benefits of viewed as a commodity for trading purposes and a store of value when it comes to the financial aspects of things. I do not believe crypto would overtake currencies entirely or have any kind of near term prospect for becoming a useable currency in too many regards because the prices are far too volatile. Currencies do not fluctuate the same and have consistent usable values. You could actually be financially harmed by transacting in crypto if you sold something, say a house, and then the next day the price bottomed out.

I think it should be viewed as a form of digital commodity or asset, almost a hybrid between stocks and commodities such as gold and silver.

From a trcnological standpoint as well this is where the greatest impact on society as a whole will lie, not in the daily gains and losses of the market but from the technological advances that we'll see come from Blockchain technology.
