Thanks for your valuable addings, @denmarkguy. As always I appreciate them much!
Your words remind me of one of my favorite quotes regardings new technologies:
Mass adoption can only happen if we provide accessibility.
With regards to the word "currency" I've learned that it comes from Middle English: curraunt = "in circulation". Even though crypto currencies don't circulate physically they are traded and transferred from one account to another. So I guess the basis idea of a "moving something" applies still :-)
I'd love to buy a Café Latte at Starbucks with a Steem Card!!! 🤑🤑🤑
