Inflation can be good
It's not well known that the drawback of hard money (gold, silver, bitcoins) is that if they are adopted as a nation's sole currency, they inevitably drive the vast majority of the population into serfdom. If they are combined with usury (lending money for interest) this happens so much faster.
In the middle ages the gold all resided in rich men's treasure chests, the silver all resided in merchants safes, the copper resided in freemen's hidey-holes and everyone else was a serf living fifty meals away from death by starvation. It took a war (usually civil war) or a plague to (temporarily) jog the system out of otherwise permanent economic stagnation, depression and deflation.
Eventually the Black Death laid the seeds of a modern economy, by killing half the population, thereby making labour scarce and redistribiting the rich men's coffers (thereby creating inflation). The Spanish then unwittingly kept the ball rolling by plundering all the gold from the natives of what became Latin America ... which imported inflation first to Spain and then, in a more beneficial form, to the rest of Europe. By the time that stimulus dried up, fractional reserve banking and paper money had evolved to a modern form. Which has its own problems, especially when no longer judged against gold bars, but which (so far?) has not proved quite as disastrous as the alternative.
If bitcoins ever become a global store of value as well as a global medium of exchange, we are in big trouble (deflationary collapse). Ditto, if there's ever one world paper currency and one world central bank (corruption, then inflationary collapse). It's competition between multiple currencies that keeps the present system going despite the periodic crises. There's probably a parallel to be drawn with a natural ecosystem.
