Excellent post regarding some important facts and trends. And I love the term "blockonomics." (Did you coin it?)

I particularly liked your reference to the utter failure of the euro to bring prosperity to the EU, or at least to bring an equitable share of prosperity to many eurozone members.

The most astute observers point out that separate economies require separate currencies in order to interact efficiently with them. In fact, the "natural" currency fluctuations are an essential mechanism of international trade and commerce. Without that mechanism, we get ... well, Europe, circa 2018.

With the sudden increase in the number of cryptocurrencies over the past few years, a similar question arose (as you implied in your phrase "a singular currency to run every market.") And just like many others, I wondered if it's viable to have hundreds of cryptos.

As you further state / imply, it can be beneficial to have numerous cryptos. Many will not necessarily be "competing," but fulfilling their own purpose and answering the needs of those who use them.

May a hundred blockchains bloom, and a thousand cryptos contend.
