This is an interesting thread. Specially seeing yahoo on the list which now exists rather as a brand than organization, so not too inspiring. Other than that, you have made your point.
It's not only yahoo but also other giant like amazon on the top of the list. I am not sure who is bigger - yahoo or amazon but I have always thought that amazon is bigger than yahoo. I may need to do some google search.
Amazon as the largest company in the world it has surpassed microsoft. Basically the world needs the time to adopt such a new technology and this looks interesting amazon has started from nothing and i sure about the future ot crypto. We need a lot of time for that,
