This. I'm amazed state currencies still have the slightest credibility. In the computer age, the least that can be asked about a currency is that the total amount in circulation should be public. And it's not. The monetary aggregates are only estimated, and we're supposed to trust the economists who do those estimations. And let's not forget about forgery : not later than today I was reading an article about fake euro coins, and there are lots of them. When you think about it, the fact that we still use pieces of non-precious metals and paper notes for money is ridiculous. They are certainly very easy to counterfeit for anyone with enough means and determination. The whole thing is a mess. Cryptocurrencies can not be forged and their ledger is public. That alone makes me trust them more than I trust state currencies.
