I have always struggled to distinguish many so-called crypto-currency schemes from Ponzi schemes but this seem to support my view: RTE news : Bitcoin heading on "road to irrelevance" - ECB

It's that story about #sardine #trading in California when sardines became scarce. The traders bid them up and the price of sardines soared. One day a buyer decided to treat himself to an expensive meal and opened a can. He became ill and told the seller the sardines were no good. The seller said, “Yes, but these aren't eating sardines, they're trading sardines.”
That's #crypto to me. There are a hundred tokens out there being traded, but I don't see people using them to buy stuff.
