Again, not links to white papers, ".io" startups, articles filled with "it is revolutionary" and such buzzwords, etc. The hype wagon is getting heavy. Where are the results? Where are the "Use of Bitcoin has been skyrocketing in X market" headlines, where X is not "ransomware"?
So Coinbase Commerce [0] enabling thousands of Shopify [1] stores to accept Bitcoin and the like isn't a legitimate use-case?

Sorry, if you go through and read that article, it doesn't look good at all. No, cryptocurrency will not help us go green, just to single out the worst whopper. It was written in 2017 and suggests that payment using cryptocurrency for travel, online publication, etc will be widespread. Four years later, nope.
