All excellent points. But your criticism of Bitcoin is redundant if the dollar collapses. That's the expectation. Our national debt will eventually get so big that the interest payed on it exceeds the revenue of the US government, which will either result in another Venezuela like situation of hyperinflation, defaulting followed by a possible world war 3, or increased taxation to the point rebellion.
Either way, the dollar will collpase and chaos will take its place, eventually. Some, like Jeff Berwick, have estimated that it will be as soon as 2020. This is the purpose of Bitcoin: It's our lifeboat.
And since EOS can handle millions of transactions at no fees, maybe crypto can sustain the entire world. We can only hope, because someday, we may need it's help.
