The book doesn't yet have a glossary for a quick reference of definitions. So in the example, Bitcoin wouldn't necessarily be a debt currency, in an abstract use of the term. But it would share the characteristics and consequences of temporal and spatial asymmetry with debt-currencies?
BTC issuance is based on the imaginary model of rare metals : easy to issue in the beginning, more difficult to find with time, and with a fixed quantity.
We know for sure that rare metals currencies lead to crisis, take 1929 for example, while having been extracted and used as currencies since 3000+ years. BTC extraction is reduced to 150 years, no surprise it will go through structural crisis due to issuance model (not even considering the energy consumption).
To me, debt currency is _better_ than fixed monetary mass like BTC or gold : at least, _some_ humans can decide to create more money when the new generation needs it.
The problem is that only _some_ humans can decide it. They decide what are the main values for this generation. With libre currency, _all_ members create the currency at the same rate and can decide what is value and what is not.
Updating the backpage of Mnemosyne's Heretic. It used to have a Monero address for donations, but the new page will have Ğ1 instead. This is how it looks so far. Not sure if I should do more or keep it simple.
