Good article and pretty pictures. One big difference between the paper and the crypto is that the crypos have been limited in suppy. Scarcity can add value. However with number of different cryptos it falls back to faith.
One other advantage of cryptos is what they call fungable. Sorry if I can't spell it. Trading easilly over borders and through the internet is valuable.
YAHsways
😊 I also agree to a certain extent regarding fungable but the main reason to me that cryptos are better, is that it cant be printed into oblivion.
