Crypto's have an Achilles heel that gold does not have when used as a digital currency. A crypto cannot transact P2P in the face of a fiat asking price. It must always make a hop. This is not the behavior of a currency because it actually relies on currency in order to bridge it into the real economy.
Crypto can be used to buy things but if it cannot transact with debt-free settlement as a popular currency, what true effect can it provide in the macro challenge of supporting the purging of debt based currency ? Debt must be purged, systemically ! True debt-free P2P is vital to this debt purging mission statement.
