Where does the value of Bitcoin come from?

BTC is an open ledger for a cryptocurrency. There is no treasury or real estate to back the currency. BTC is simply a ledger of transactions.

People are willing to engage in cryptocurrency because they trust the ledger.

Pre-war Germany was a in a terrible situation. The fiat currency was devalued. Industry had more faith in the promissory notes than they had in the currency.

The notes were still creating a bubble economy which probably hastened Germany's march to war.

There have been thousands of currency bubbles in history. It is foolish to call any of them miracles.

Most bubble economies suffer a bust after the boom.
